INSTALLATION

The installation and set-up of the water heater must be carried out by a competent person in conformity with the applicable norms and sanitary standards in force and with any provisions outlined in this manual.

Wall-mounting

Water heater mounting is made on the main wall using brackets and fastening hooks (not included in the supply). Fastening hooks with a diameter of at least 12 mm are recommended.

• Depending on the model, you will need 2 or 4 of the fastening hooks.
• The fastening must support a weight that is three times higher than the weight of the water heater filled with water.
• It is not allowed to mount the vertical models horizontally, and horizontal models – vertically.
• The appliance should be installed as close as possible to the point of use to limit heat dispersion.
• Allow for a clearance of at least 50 cm around and from the ceiling – 10 cm for maintenance activities.
• The fastening of hooks to the wall must prevent inadvertent movement of the bracket of the water heater over them. After installation, be sure to check the security of the attachment.
• To prevent the property of the customer and/or third party from damage caused by failures of the hot water supply system it is recommended to mount the boiler in the premises provided with a waterproof floor and drainage system. Also, never put objects sensitive to water under the boiler.

Hydraulic connection

• Installation of the safety valve included in the package is necessary.
• Do not install any cut-off valve between the safety valve and the inlet of the tank and do not block the drain hole of the safety valve.
• Demountable connectors should be used for the water heater connection to the water supply system.

Standard connection (Fig. 1)

• With a standard connection, the heater is operated under the pressure defined by the pressure level in the main supply line. The safety valve supplied (A in Fig. 1) must be installed on the cold water inlet of the water heater (the inlet tube is marked with the blue-collar). It is recommended to turn the safety valve no more than 3-4 turns, providing sealing with fluoroplastic tape, flax, or other water-proof sealing material.
• Connect the inlet of the safety valve to the cold water line with a flexible hose. If necessary, mount a cut-off valve.
• Connect a pipe or a hose for hot water removal to the draw-off point to the hot water outlet of the water heater (the outlet tube is marked with the red collar).
• For easy maintenance, it is recommended to install a “T” piece union (B in Fig. 1) between the inlet and safety valve of the water heater. This “T” piece union will help to drain water from the water heater without turning the safety valve.
• To facilitate the access of air into the tank when draining water, it is recommended to install an additional “T” piece union equipped with a cut-off valve (D in Fig. 1).
• In the heating mode, the drain hole of the safety valve may drip water. To drain this water, a drain hose is used which must be laid with a downslope. The temperature in the area where the drain hose is laying must not drop below 0˚C. If the water pressure in the water line is close to the actuation pressure of the safety valve, a reducer must be installed upstream of the safety valve. To avoid clogging of water fittings or shower heads, debris, and dirt must be removed from the pipes.
• For some models due to their design, installation of hydraulic connections, including installation of the safety valve, may be done only with the removed plastic cover of the water heater. After installation of the hydraulic connections, this cover should be put back in place and fixed with its screws.
• Connect the water heater inlet and outlet only with pipes or fittings that can withstand temperatures over 80˚С at a pressure exceeding that of the working pressure. Therefore, we advise against the use of any materials which cannot resist such high temperatures.
• In addition, it is recommended to connect the hose for the water drain (C in Fig. 1). This hose allows directing drained water from the water heater into the sewer or other place of your choice.
• Connection to open tank (Fig. 2)

Water is supplied to the heater from the tank by gravity. For this purpose, the tank water outlet “T” piece union supplying water to the heater and other places must be installed higher than the water heater top. The safety valve is not necessary in this type of connection.

Electrical connection

• Electrical wiring should be done by a competent person, ensuring it complies with safety norms. The manufacturer will not be held responsible for any damage caused by the incorrect earthling of the system or for fault defaults of the electricity supply.
• After the tank of the water heater is filled with water and the system is checked for leaks, plug in the moisture-proof electrical plug of the water heater.
• If the water heater is supplied without a power supply cable, use a cable featuring the same characteristics (type H05VV-F 3×1.5 mm², Ø 8.5 mm in diameter) for connection. The power supply cable should be threaded through the relevant hole on the cover of the appliance and fixed to the terminal board. Then every wire should be fixed in place by the corresponding screw.
• The water heater must be earthed. The earth cable (of yellow-green colour and longer than that of the phases) should be fixed to the terminal marked by the symbol. Block the power supply cable using the wire clamps.
• Make sure that the power supply voltage conforms to the value indicated on the data plate of the water heater. Use cables of the appropriate section.
• To disconnect the unit from the electrical supply use a bipolar switch conforming to CEI-EN standards with contact opening at least 3 mm. It is recommended to install fuses in the electricity supply circuit.
• “T” piece unions, extension cords, and adapters are not allowed. Do not connect the earthling cable of the appliance to water and gas pipes.

STARTING AND OPERATION

Commissioning

• Before connecting the appliance to the electricity source, fill the tank up with mains water. To do this, turn on the domestic mains tap and the hot water tap.
• Once the water heater is full, the water will flow from the domestic mains tap. Visually check for water leaks from the flange and slightly tighten it, if necessary.
• Power the appliance at the switch.

Temperature control

• In models equipped with external control, the water temperature can be controlled by a handle connected to the thermostat in accordance with marks.
• If an appliance model does not have an external temperature controller, the temperature can be set by turning the adjusting screw of the thermostat in the range marked by the signs “+” and “-”. To do this, disconnect the water heater from the power supply and remove the plastic cover of the appliance. It is recommended to install the controller in a position corresponding to approximately 75% of the maximal value. In this case, the appliance is operated in economy mode, significantly reducing the rate of scale formation.

MAINTENANCE AND REPAIR WORKS

• All maintenance and repair works should be carried out by a competent person only in conformity with the safety norms and with any provisions outlined in this manual.

Water Drain

If there is a chance that the ambient temperature drops below 0°C in the room where the appliance is installed, drain water from the water heater.

• To do this, the following steps should be done:
  • Disconnect the appliance from the electrical supply;
  • Make sure that the water in the appliance is of safe temperature;
  • Turn off the tap of the cold water supply to the water heater;
  • Turn on the hot water domestic mains tap for discharge of pressure inside the tank;
  • Turn on the tap (D in Fig. 1) to allow air into the tank. If it is absent, remove the supply tube to the hot water pipe of the water heater (marked with the red collar);
  • Connect the drain hose directed into the sewer to the drain cock (B in Fig. 1) and open it. If there is no a “T” piece union with the drain cock, remove the supply pipe to the cold water inlet of the water heater (marked with the blue-collar), connect the drain hose directed to the sewer to the cold water inlet;
  • After draining, make sure there is no water inside the water heater.
• Freezing of water inside the water heater leads to irreversible changes and defects.
• It invalidates all warranty liability on the part of the manufacturer.

Replacing internal parts

• Disconnect the heater from the power supply. Remove the cover. To work with the thermostat, pull it straight out and disconnect from the power supply.
• To work on the heating element and the anode, the appliance must first be emptied. For models with an autoclave flange, remove the nut (D in Fig. 3), remove the flange holder (S in Fig. 3), and open the flange (F in Fig. 3) by pressing it inside. Remove the flange by turning it on its axis.
• For other models, remove 5 nuts (C in Fig. 4) and remove the flange (F in Fig. 4). The heating element and anode are attached to the flange. When assembling the appliance, be sure to put the heating element, flange seal, and thermostat into their initial position. We recommend the flange gasket is replaced every time it is removed.

• Use the original spare parts of the manufacturer only.

Periodical maintenance

Magnesium anode

The magnesium anode is an integral part of the protection system of the water tank against corrosion. Given that aggressive properties of water cause faster wear of the magnesium anode, conditions of the magnesium anode should be checked ANNUALLY. In case of severe wear, the magnesium anode must be replaced. The warranty for a water-containing tank with the worn magnesium anode (residual volume is less than 30%) is not valid. To replace the anode, disassemble the heating element and unscrew from the support bracket.

• The magnesium anode should be replaced at least 1 in 24 months (excluding the water heater with the inner tank of stainless steel).
• The magnesium anode is a consumable item that cannot be replaced under warranty.
• Following the rules of scheduled maintenance will allow you to ensure the long life of the water heater.

Safety valve

• The safety valve (pressure safety device) must be inspected regularly to check that it is not clogged. Remove the limescale deposits if necessary. If the safety valve is equipped with a lever, a regular valve correct operation check procedure can be performed with its help.
• The drainage pipe of the safety valve may generate water droplets. It is not a defect; it is due to the relief work function of the valve – pressure relief that occurs when water is heated in the enclosed space of the inner tank.

RCD (Residual Current Device )

If the appliance comes with a residual current device (RCD) located on the power cord, and then after the tank of the water heater is filled with water and the system is checked for leaks, put in the moisture-proof electrical plug of the water heater and do the following:

• Press “RESET” on the RCD housing, and the LED will be lit, indicating the electricity supply.
• Then press “TEST”, power will be off, as well as the LED. Press “RESET” again. If the power LED lights up, it means that the appliance is safe to use.
• If you press the “RESET” knob, but LED does not light up, contact the Technical Assistance Centre for advice by a competent person.

Please note:

• When you first start the water heater, as well as on each start after disconnecting make sure that the water heater was filled with water, and only then make its connection to the mains.
• When the power cord is damaged it must be replaced by a special cord. This cord can be purchased at the Technical Assistance Centre.
• Hot water whose temperature exceeds 50°C at the user taps may immediately cause severe burns or even death. Children, the medically fragile, and the elderly are more exposed to the risk of burns.
• Water may drip from the water heater, so do not leave valuable items and equipment under the appliance.
• If there is a chance that the temperature drops below 0°C in the room where the appliance is installed, drain the water from the water heater.
• Outlets must be properly earthed.
• While in operation, periodically clean the inner tank of the water heater. Particulate contaminants that are present in tap water may accumulate there.

When there is strong scaling in the heating elements or heavy settlings, drain water, remove the heating elements, and clean. When assembling them back follow these actions: tightening bolts should be done evenly, with no significant force applied, and the fixing support should not be tilted. Electricity supply connection can be made only after filling the water heater. 4.4.9. When the water heater is not used for a long time, shut off the cold water supply valve and disconnect the water heater from the mains. If necessary, drain the water.

• When water pressure exceeds 5 bar, drops of water may appear in the drainage hole of the safety valve, or it may cause a leak.
  • A rare drip at the drain hole of the safety valve indicates normal operation of the heater.
  • Frequent drip at the drain hole of the safety valve means that the water pressure is higher than normal. In this case, the pressure reducer must be installed in the cold water supply pipe to reduce pressure at the maximum distance from the heater.
  • To remove appearing water drops, a discharge tube can be used, the end of which should be directed down to the drain, and it should not be blocked.
• In case of water overheating, a thermal fuse conforming to European safety standards CEI-EN breaks the electric circuit at both leads to the heating element.
• Traces of the thermal insulation on the top of the outer shell are the technological features of the production process and are not defects.
• Before making a call to the service center, make sure that the problem is not related to water or power outages.
