The Thermex water heater (80 liters), instructions for use of which will be described below, is manufactured using modern technologies, and high quality materials are used in the process. Such devices have shutdown protection, which ensures electrical safety during operation. This equipment can be used to provide hot water to industrial and domestic facilities that have a cold water supply. The system must maintain a pressure level of 0.05 to 0.6 MPa. The device must be used in heated indoor areas. The device cannot be operated in continuous flow mode.

User manual

If you decide to choose a Thermex water heater (80 liters), the instructions for use of which will tell you how to extend the life of the device, you should know that models are offered for sale with mechanical and electronic controls. In the first case, on the external panel there are keys responsible for selecting power. By using both, you will provide a power equal to 2 kilowatts. This will allow you to meet your needs based on the amount of hot water you need to receive.

When using a heater, you can adjust the temperature using the toggle switch located on the control panel. By turning it counterclockwise until it stops, you disconnect the water heater from the network. If you turn the regulator clockwise, you can increase the coolant temperature to 75 degrees.

Types of Termex heaters

It should be noted that under the THERMEX brand you can only find electric water heaters in the retail chain; the company does not produce any other household appliances. Therefore, it is the only one in Europe that has occupied this market segment for the last 65 years and produces only boilers of various designs. Another important feature of the company is that no manual labor is used in the assembly of all Termex products.

At the moment, the manufacturer produces 4 types of electric devices for heating water:

• storage (boilers);
• instantaneous water heaters;
• indirect heating boilers;
• flow-storage.

As for storage-type devices, the most popular on the market, the company produces as many as 11 model ranges of various boilers. This allows you to satisfy any needs of customers and makes it possible to choose a water heater for yourself both in terms of cost and functionality.

The simplest and most affordable Termex boiler can be selected from the CHAMPION and CHAMPION SLIM model ranges. The line of the first row includes 13 products with a capacity from 10 to 300 liters, the second - 7 devices with a capacity of 30-80 liters, all cylindrical in shape. These hot water boilers are equipped with a steel tank coated on the inside with glass porcelain enamel; the general design of the units is classic with a minimal set of automation, as shown in the figure:

The THERMEX SPRINT line of water heaters is also equipped with enameled steel tanks with a capacity of 30 to 100 liters, but of a rectangular shape. In addition, the devices have a high-speed heating mode. The remaining 8 model series are already equipped with stainless steel tanks; general information about them is presented in the table:

It is worth noting that among the types of devices, there are a total of 43 pcs. you can choose both a regular and a horizontal water heater, with a minimum and an expanded number of functions. That is, you can choose to suit every taste and color.

If an apartment or private house requires an instantaneous water heater, then 2 lines of models are sold under the Termex brand: STREAM and SYSTEM. The first includes 6 products with a power from 3.5 to 7 kW, the second also includes 6 devices with 6-10 kW heating power. The shape is rectangular, suspended.

The COMBI series consists of 6 indirect heating boilers with a built-in heating element for heating water in the event of a boiler system shutdown. For obvious reasons, this line does not have a 50 liter water heater; the series starts with a capacity of 80 liters, the largest water heater holds 300 liters. The design of the devices is floor-standing, the shape is cylindrical. The power of the heating element is 1.5–3.5 kW.

3 modifications of flow-storage boilers are drop-shaped and designed for hanging on the wall. The maximum heat output is the same for all - 2.5 kW, the smallest device can hold 10 liters of water, the largest one - 30 liters.

Using an electronically controlled model

The Thermex water heater (80 liters), instructions for use of which are included with the device, can be electronically controlled. In this case, turning it on or off can be done with the left button, which is located on the panel. The heating temperature will appear on the display, and after 2.5 seconds you will be able to see the current temperature of the water in the heater. If you need to change the water heating temperature when there is an electronically controlled model, you can use one of the three touch keys.

The water heats up instantly, passing through a copper circuit in which

heating elements are located (Fig. 2). The required temperature is achieved by adjusting the water flow. The diagram (Fig. 3) shows the dependence of the temperature difference at the inlet and outlet on the amount of water flow.

The temperature of tap water can fluctuate significantly throughout the year: from 5°C to 20°C. This means that at the same outlet water temperature, the water flow in winter will be less than in summer. To obtain an effective water jet when using the shower, use the included shower head.

After supplying water to the EWH and establishing the minimum permissible

flow (1.8 l), the relay will automatically turn on thermoelectric heaters (heating elements). When the water flow at the inlet decreases below the minimum allowable value, the heating elements are automatically turned off, and accordingly, heating will stop.

Means

Different operating modes

The Thermex water heater (80 liters), the instructions for use of which will allow you to install it yourself, can operate in one of several modes. When first turned on or after a power outage, the temperature is set to 75 degrees. If we are talking about models with an electronic panel or a digital sensor, then after a power outage the equipment goes into “Demo” mode, which involves a demonstration mode. The heating elements will not be turned on.

Thermex electric storage water heaters can be taken out of demo mode by simultaneously pressing and holding the keys for 5 seconds, which are located on the control panel and indicate up and down movement. The device can go into standby mode, which is accompanied by the company logo flashing, and the indicator indicates the water temperature level in the heater.

Connection to the water supply system

The Thermex water heater, the connection of which is best left to specialists (only in this case will the equipment warranty apply), must be installed in several stages. Initially, a safety valve is installed at the cold water inlet. In this case, it is important to ensure the tightness of the connection and use an insulating material such as FUM tape. The manufacturer prohibits using a water heater of this brand without a safety valve or operating it in tandem with valves from other companies.

During the use of the described water heater, drops may appear that leak from the drain beak of the valve. This may be due to excessive heating pressure. Users are advised to attach a silicone or rubber tube to the drainage beak to ensure moisture drainage. The diagram of the Thermex water heater is presented in the article; it should help you if you need to connect the equipment to the water supply system. The technician must remember that the cold water supply pipe must be located below the hot water intake pipe. In this process you need to use metal-plastic, copper or plastic pipes. A flexible plumbing line will help with these manipulations.

It is recommended to supply coolant to the water heater after the mud trap, which should be located on the cold water main.

Description and principle of operation of EWH

The external housing of the EWH, depending on the model, is made of various high-quality materials - impact-resistant plastic, low-carbon or special polished stainless steel. The internal tank is made of high-quality stainless steel containing titanium, which ensures high corrosion resistance and, as a result, long service life. The space between the outer casing and the inner tank is filled with polyurethane foam - modern, environmentally friendly thermal insulation with the best heat-saving characteristics. Models RZL-VP, RZL-VS, RSD have two threaded pipes: for cold water inlet (with a blue ring) and hot water outlet (with a red ring), and models RZL-HP, RZL-HS, RZB, RZB-D, RZB-F, RZB-L are equipped with an additional drainage pipe (with a red ring, closed with a metal plug) for draining water and washing the internal tank.

There is a thermometer on the front side of the EWH (model RZL-HS, RZL-VS, 30l -150l). The location of the control panel depends on the model and type of EWH: RZL-VS, RSD - bottom, RZL-HS - right, RZB, RZB-D, RZB-F, RZB-L, RZL-HP, RZL-VP and ROUND PLUS series models - on the front side.

A tubular electric heater (TEH) and thermostat and thermal switch sensors are mounted on a removable flange. The heating element serves to heat water and is controlled by a thermostat, which has smooth temperature control up to +75°C. The thermostat automatically maintains the water temperature at the level set by the user. The temperature control knob is located on the mechanical control panel. Electronically controlled models have a touch control (Fig. 4). The thermal switch serves to protect the EWH from overheating and disconnects the heating element from the network when the water temperature exceeds +95°C (Fig. 2).

The RZB10 model is equipped with an autonomous unregulated thermostat located under the top cover of the device. Models RZB10 and RSD are equipped with a pilot lamp that induces the heating mode of the heater. The thermal switch in models RZB10 and RSD is located under the top cover. The operating mode indicator of the EWH models 30L - 150L is the backlight lamps of the power selection keys: they light up when the water is heated and go out when the water heating temperature set on the thermostat is reached. In models with electronic control, the indication is carried out by the control lamp L1 (Fig. 4) - it lights up when the set temperature is reached.

An RCD is mounted on the electrical cord of the device, which ensures that the EWH is disconnected from the power supply network in the event of a leak or breakdown of the supply voltage to the grounded elements of the device. Silver models in their design contain an electronic device with a silver anode, which ensures disinfection of heated water. This series of water heaters is a “new generation” product that takes care of your health. The safety valve functions as a check valve, preventing water from the water heater from entering the water supply network in cases of pressure drop in the latter and in cases of increasing pressure in the tank when the water is very hot, and also functions as a safety valve, relieving excess pressure in the tank when the water is very hot. When the water heater is operating, water may leak from the safety valve outlet pipe to relieve excess pressure for the safety of the water heater. This outlet pipe must remain open to the atmosphere and be installed permanently downward and in a frost-free environment.

It is necessary to ensure that water is drained from the outlet pipe of the safety valve into the sewer system by providing appropriate drainage when installing the EWH.

It is necessary to regularly (at least once a month) drain a small amount of water through the outlet pipe of the safety valve into the sewer system to remove limescale deposits and to check the functionality of the valve. To open the valve, it is equipped with a handle. It is necessary to ensure that during operation of the water heater this handle is in the position that closes the drain of water from the tank.

Safety instructions for working with the Termex water heater

The electrical safety of the EWH is guaranteed only if there is effective grounding, carried out in accordance with the current rules for installing electrical installations. Plumbing connections and shut-off valves must comply with the parameters of the water supply network and have the necessary quality certificates.

During installation and operation of EWH it is not allowed:

• connect the power supply if the EWH is not filled with water;
• remove the protective cover while the power is on;
• use EWH without grounding;
• include EWH in the water supply network with a pressure greater than 0.6 MPa;
• connect the EWH to the water supply without a safety valve;
• drain water from the EWH when the power supply is on;
• use spare parts not recommended by the Manufacturer;
• use water from the EWH for cooking;
• use water containing mechanical impurities (sand, small stones), which can lead to disruption of the operation of the EWH and the safety valve;
• change the design and installation dimensions of the EWH brackets.

Installation and connection

ATTENTION! All plumbing and electrical installation work must be carried out by qualified personnel with a mandatory entry in the “Connection Mark” section (see the “Manufacturer’s Warranties” section).

Placement and installation of the device

The installation of the EWH is carried out in accordance with the markings indicated on the housing and the following table:

It is recommended to install the EWH as close as possible to the place where hot water is used to reduce heat loss in the pipes. The EWH is suspended from the housing brackets on anchor hooks fixed in the wall. Installation of hooks in the wall must prevent spontaneous movement of the EWH brackets along them.

To service the EWH, the distance from the protective cover to the nearest surface in the direction of the axis of the removable flange must be at least: 30 centimeters - for models 5-80 liters; 50 centimeters - for models 100-150 liters. ATTENTION! In order to avoid causing harm to the property of the consumer and (or) third parties in the event of malfunctions of the hot water supply system, it is necessary to install the EWH in rooms with waterproofing of floors and drainage into the sewer, and in no case place objects exposed to water under the EWH. When placing the EWH in unprotected premises, it is necessary to install a protective tray under the EWH with drainage into the sewer. If the EWH is located in places that are difficult to access for technical and warranty service (mezzanines, niches, ceiling spaces, etc.), the dismantling and installation of the EWH is carried out by the consumer independently or at his expense. Note : the protective tray is not included in the EWH package.

Connecting a Termex electric water heater to the water supply

Install the safety valve at the cold water inlet, marked with a blue ring, tightening it 3.5 - 4 turns, ensuring the tightness of the connection with any waterproofing material (linen, FUM tape, etc.). It is prohibited to operate the EWH without a safety valve or use valves from other manufacturers.

Rice. 1. Connection diagram of the EWH to the water supply system

During operation of the EWH, you can observe the appearance of drops from the drainage beak of the safety valve (relieving excess pressure when heating the water). It is recommended to attach a rubber or silicone tube of the appropriate diameter to the drainage beak to remove moisture. Connection to the water supply system is made in accordance with Fig. 1 only using copper, metal-plastic or plastic pipes, as well as a special flexible plumbing connection. It is recommended to supply water to the EWH through a mud filter installed on the cold water main (not included in the delivery package). After connecting, open the cold water supply valve to the EWH and the hot water tap on the mixer to ensure the outflow of air from the water heater. When the EWH is finally filled, cold water will flow from the mixer tap in a continuous stream.

When connecting the EWH in places not supplied with running water, it is allowed to supply water to the EWH from an auxiliary tank located at a height of at least 5 meters from the top point of the EWH, or using a pumping station.

Note : to facilitate maintenance of the EWH during operation, it is recommended to install a drain valve in accordance with Fig. 1 (for models not equipped with a drain pipe (not included in delivery)). If the pressure in the water supply system exceeds 0.6 MPa, then a reducer (not included in the delivery package) must be installed at the inlet in front of the EWH to reduce the water pressure to normal.

Connecting the device to the mains

ATTENTION! Before turning on the power, make sure that the EWH is filled with water.

The EWH is equipped with a standard power cord with a plug and an RCD. The socket must have a grounding terminal and be located in a place protected from moisture. The socket and the electrical wiring connected to it must be designed for a rated power of at least 2000 W. Insert the plug into the socket and press the button located on the RCD.

Additional connection recommendations

As soon as the Thermex electric storage water heaters are connected, the cold water supply valve can be opened, this also applies to the hot water tap on the mixer. This way you can ensure air flow out of the device. When cold water flows in a continuous stream from the mixer tap, this will indicate that filling the water heater has already been completed. If the device is installed in a place where there is no water supply, cold water can be supplied from an auxiliary container. However, it must be placed at a height of 5 meters from the top point of the device. If this is not possible, then it is additionally permissible to use a pumping station.

Maintenance (MOT) Termex

During maintenance, the presence of scale on the heating element is checked. At the same time, sediment that may form in the lower part of the EWH is removed. If scale has formed on the heating element, it can be removed using special cleaning agents or mechanically. It is recommended that a year from the moment the EWH is connected, the first maintenance is carried out by employees of a specialized organization and the timing of subsequent maintenance is determined based on the intensity of scale and sediment formation. This action will maximize the life of the EWH. In Silver models, it is necessary to replace the silver anode once a year by a specialized organization.

Attention : the accumulation of scale on the heating element can cause damage to it. Note : Damage to the heating element due to scale formation is not covered by the warranty. Regular maintenance is not covered by the manufacturer's or seller's warranty.

To carry out maintenance, you must do the following:

1. turn off the power supply to the EWH;
2. let the hot water cool or use it through a mixer;
3. shut off the flow of cold water to the EWH;
4. unscrew the safety valve or open the drain valve;
5. put a rubber hose on the cold water supply pipe or drain valve, directing its other end into the sewer;
6. open the hot water tap on the mixer and drain the water from the EWH through the hose into the sewer;
7. remove the protective cover, disconnect the wires, unscrew and remove the support flange from the housing;
8. If necessary, clean the heating element from scale and remove sediment from the tank;
9. assemble, fill the EWH with water and turn on the power.

In models with a drainage pipe, it is enough to shut off the flow of cold water into the EWH, unscrew the plug on the drainage pipe and open the hot water tap. After the water has drained, you can open the cold water supply to the EWH for a while to further flush the tank. When carrying out maintenance of the EWH by a specialized organization, a corresponding note must be made in the service coupon. Subject to compliance with the rules for installation, operation, and maintenance of the EWH and the quality of the water used meets current standards, the manufacturer sets the service life of the EWH to be 7 years.

Note

Today, electric storage water heaters are very popular. Thermex reviews are positive. These devices can also be operated according to an easier principle. To do this, it is recommended to install a drain valve. This applies to those models that do not have a drain pipe included. If it is necessary to install a water heater in a system where the pressure is greater than the above, it is necessary to place a reducer at the inlet in front of the equipment, which will have to be purchased additionally. With its help, you can reduce the water pressure to the nominal level.

Water heater Termex 50 liters

Distinctive features

high-tech material glass porcelain

Between the walls of the housing and the internal tank there is a thermal insulating material - polyurethane foam. It is necessary to contain the cooling of the water, because with it the loss of temperature is a maximum of one or two degrees per hour.

Water heating heating elements are susceptible to the harmful effects of scale. To avoid their formation, a magnesium anode is built in, which is recommended to be changed once a year. Step-by-step instructions are included in the kit.

Popular models of 50 l boilers

The most popular devices are ID, IS, IF models.

• Thermex ID. This vertical water heater is as reliable and economical as possible. According to the developers, the design of the boiler prevents problems from occurring. It has a safety system during operation that prevents the formation of corrosion. The inner tank is coated with stainless steel. This model is equipped with a super-flat body with a depth of 23.5 cm, made of structural plastic, two internal tanks connected together. The boiler design saves space and can withstand high pressure. The front panel has buttons for controlling the thermostat and power modes.
• Termex IS is equipped with a self-diagnosis function, which allows you to independently make decisions regarding operation in case of problems. Water heating occurs automatically. The advantages of the model include compact dimensions, ease of power adjustment, and ease of installation. The water temperature heats up to 70 degrees. The device is controlled using an electronic menu. The model has a vertical design, is equipped with a valve for draining liquid, a thermostat located on the front panel and a capillary safety thermostat.
• Termex IF is equipped with an external thermostat for comfortable control. Vertical model coated with fine enamel. The built-in magnesium anode has an increased mass, which protects against corrosion more effectively than other models. The heating element is coated with a composition to prevent the formation of salt deposits.

Checking the water heating unit

A boiler, like any other device, requires periodic maintenance. So, before turning it on for the first time, it will be necessary to check the serviceability and functionality of all its systems. It is worth doing this even after the water heater has been turned off for a long time, or after severe frosts.

In summer, in most apartments with centralized water supply, hot water is turned off. During this period, utility services carry out repair and maintenance work. As an alternative, the vast majority of people choose to buy tankless or storage water heaters, depending on their needs and budget.

It’s not enough to just buy a device; you need to figure out how to turn on the water heater. Although the process is quite simple, some still have doubts.

The range of equipment includes storage and instantaneous water heaters, and connecting each of them requires a certain sequence of actions, most of them approximately the same.

Boiler characteristics

The boiler is installed as an alternative or main water heating system

All water heaters can be divided into two groups according to the method of heating water: instantaneous and storage.

Storage models are equipped with a tank in which water is heated using a heating element. Thanks to the insulation of the tank, the water maintains its temperature for a long time. The tank volume can exceed 300 liters. Large-sized products are used in large country houses. Storage units with a capacity of about 10 liters can be installed in apartments.

Flow-through models are suitable for domestic use in apartments. Their operating principle is to heat the liquid when the tap is turned on. These are compact devices that are installed next to the water tap.

By type of fuel there are:

• Gas appliances. They are quite expensive, but pay for themselves within two years of constant use.
• Electrical. The models themselves are low in cost, but will require significant electricity costs.

Based on the listed characteristics, the owner of a house or apartment selects which boiler suits him best.

What is it needed for

Installing a safety valve prevents the pressure inside the device from increasing above the standard value. What causes blood pressure to rise? As you know, when heated, water expands, increasing in volume. Since the boiler is a sealed device, there is nowhere for the excess to go - the taps are closed, and there is usually a check valve at the supply. Therefore, heating the water leads to an increase in pressure. It may well happen that it exceeds the tensile strength of the device. Then the tank will explode. To prevent this from happening, they install a safety valve for the water heater.

This is what an installed pressure relief valve looks like in a water heater

Maybe there is no need to install a safety valve, but simply remove the non-return valve? At a sufficiently high and stable pressure in the water supply, such a system will work for some time. But the solution is fundamentally wrong, and here’s why: the pressure in the water supply is rarely stable. There are often situations when water barely flows from the tap. Then the hot water from the boiler is forced out into the water supply system. In this case, the heating elements will be exposed. They will heat the air for some time and then burn out.

But burnt-out heating elements are not the worst thing. It’s much worse if they get hot, and at this time the pressure in the water supply rises sharply. The water that gets on the hot heaters evaporates, a sharp increase in pressure occurs - with a jerk - which leads to a guaranteed rupture of the boiler flask. At the same time, a decent volume of scalding water and steam escapes into the room under high pressure. What this could mean is clear.

Peculiarities

The body of the Thermex water heater is made of materials such as impact-resistant plastic, low-carbon and stainless steel with anti-corrosion coating. The internal container is made of titanium alloy, which increases the material's resistance to corrosion. The body and the internal tank are separated by polyurethane foam, which acts as a heat insulator. The control unit is installed depending on the model. Removable flange connections have thermostat sensors, a switch and a tubular heating element. Boilers with a volume of 50 liters, electronically controlled, are equipped with touch controls.

The water heater is connected only after the pipelines have been installed. It is also necessary to increase the pressure in the pipes to 0.6 mPa at a voltage of 220 V and a frequency of 50 Hz. The process of heating water in a boiler depends on its volume. So, for a water heater with a volume of 50 liters, the duration is 1–1.5 hours.

The main distinguishing features of Thermex products are the following:

• flat shape 250 mm thick;
• power, which lies in the range of 0.7–2 kW;
• the ability to supply several water intake points in one room;
• saving electrical energy;
• special design of the internal tank;
• resistance to corrosive wear and aggressive environmental factors;
• reliability and stability of the tank, which is ensured by G5 technology to temperature stresses and pressure drops in the system;
• water drainage and descaling system;
• availability of economical modes.

Like any other household equipment, the Thermex water heater has advantages and disadvantages. The advantages include the following:

• modern and stylish flat body;
• thermal insulation provided by high-density polyurethane foam, which allows you to maintain the temperature of hot water for a long time;
• saving electrical energy.

If we talk about the disadvantages, it is worth highlighting the following:

• high noise during prolonged use of equipment;
• small thermometer errors.

Thermex water heaters with a capacity of 50 liters are available in a wide range.

• Flow-through boilers are small-sized boilers that are installed in places where there is not enough space to install large water heaters. They have the undeniable advantage of quickly heating water. The disadvantage of instantaneous water heaters is that they cannot be used in rooms with several water intake points. They are used for small consumption of hot water, for example, for washing dishes.
• Storage heaters are protected from corrosion and scale, which increases the service life of the device. This is ensured by a special material - glass porcelain, from which the internal surfaces of water heating devices are made. To maintain the temperature of hot water, polyurethane foam is used, which prevents the water from cooling by more than two degrees per hour.

The device has magnetic anodes to protect against the aggressive effects of scale, which increases the service life of the equipment.

It is recommended to change storage heaters every 6 or 12 months. The main difference between storage equipment and flow-through equipment is that in the inner part of the tank there is a heating element, which is necessary to heat the incoming liquid to the required temperature. During the entire period of use, the water will be at the same temperature.

The advantage of storage types of heating devices is the ability to use equipment for several water intake points in one room.

To select the optimal 50-liter boiler, you need to study the characteristics of the product lines.

• Flat Plus has a flat white shape and is equipped with an ergonomic electronic unit, which includes a display with the heating temperature value.

It has the following characteristics:

• power – 2 kW;
• internal tank – stainless steel;
• body – plastic;
• automatic cleaning and draining of water;
• water heating time – 80 minutes.

• Champion ER is available in white, the body is made of metal and equipped with mounts for vertical installation on a surface. The advantages include small dimensions, simple and quick installation due to the lower piping. The internal surfaces of the model are protected by glass porcelain film, which prevents moisture and aggressive media from entering the equipment. The polyurethane foam liner ensures a stable temperature for a long time. Thanks to the high power, the liquid supply rate increases to 2 liters per minute. The presence of a check valve allows you to protect the tubular heating element.

• Diamond Touch is a horizontal heating equipment that is manufactured in a minimalist style with geometric shapes. There are two tanks inside the water heater, providing a flat storage design. The seams of the tanks are welded, which helps protect the tanks from depressurization. The electrical system is equipped with the ability to self-diagnosis, as well as adjust the liquid supply mode and heating level. If a fault occurs, all information about the fault is displayed on the screen.
• Praktik is small in size, which allows it to be installed in small apartments. It has a round shape made of stainless steel. By welding the seams, the seams are sealed and resistant to corrosion. The internal surfaces of the water heater are covered with a heat-insulating layer, due to which water heating and the efficiency of the equipment are stabilized. The power of the device is 2.5 kW.

Why are Thermex water heaters popular?

A distinctive feature of the concern's activities is its narrow specialization. Since its creation in 1949, the Italian company Thermex has been producing exclusively water heating equipment. Products are constantly improved due to the professionalism of the developers. The concern not only has its own production, it includes:

• scientific laboratory;
• own design bureau;
• production of components;
• a plant providing electrical appliances of its own production;
• enterprise for assembling Termex water heaters.

If the product is purchased in 160 countries, product assembly plants are located in different countries, including St. Petersburg, product consumption increases every year - is this not a guarantee of a worthy choice of a Termes water heater from a wide range of similar products.

Before installing the boiler, you need to decide on the place where heated water is most often needed, and you should also take into account the wiring to the water intake point. Any model is designed for installation either horizontally or vertically, which is noted in the equipment passport. It is best to entrust professionals with attaching the device to the surface, regulating operating modes and connecting to the electrical network. To connect the water heater, you must strictly follow the rules for connecting equipment.

To do this, you need to arm yourself with the following:

• Thermex heater;
• anchor fasteners;
• pipelines for distribution;
• flange connections, pipes and fasteners.

The heating elements are attached to the surface according to the diagram. It is necessary to know that the supports of water heating devices are measured with the center of gravity, and not vertically or horizontally. As a result, holes for anchors are drilled in accordance with the heels of the tank. After fastening to the surface, they proceed to piping. It is necessary to pay attention to the state of the electrical network. The heater must have a separate line, and the outlet must be located in close proximity to the equipment.

It is recommended to keep the plug of the device in a package until the heater is filled with water to avoid accidental switching on. Only after the container is completely filled and the seams are checked for tightness can the equipment be turned on to the network. The tank is considered full if the liquid comes out of the drain under pressure. The heater is supplied with a cord and a plug that provides grounding for the equipment. The device body also has a grounding point.

The temperature is adjusted according to the instructions after connecting the equipment.
