  1. The electric water heater must be installed on a solid wall.
  2. The wall on which the electric water heater is installed must be strong enough to support at least twice the weight of the heater filled with water, and the wall must be free of cracks and other damage. Otherwise, measures must be taken to reinforce the support or install the water heater on a special frame.
  3. If the bathroom is too small, the heater can be installed elsewhere, out of direct sunlight and away from humidity. However, in order to reduce heat loss in the pipes, the heater should be installed as close as possible to where hot water is used.
  4. When determining the site for the water heater, make sure the heater is easily accessible by leaving at least 60 cm between the bottom of the water heater and the floor, and at least 10 cm between the top of the water heater and the ceiling. This will enable easy maintenance and adjustment as required.

The water heater must be installed on a vertical wall in a vertical position. If installed in any other position or misaligned, the water heater will inevitably malfunction, causing an emergency. This will be treated by the manufacturer as a non-warranty case.

Water heater installation


Please use the accessories provided by the manufacturer to install the water heater. The electric water heater must not be mounted on the wall before you make sure that the bracket is securely installed. Any failure to do so may cause the electric water heater to fall off the wall, which may cause damage and even major incidents including bodily injuries. When marking spots for the anchor bolt holes, allow at least 60 cm clearance between the bottom of the water heater and the floor to ensure easy maintenance when required.timberk-T-WSS30-N39D-V-Electric-Storage-Water-Heater-fig-3

Once you have selected the proper site for the water heater, determine the spots for the anchor bolt holes with hooks (according to the specifications of the product you have acquired). Drill two holes of appropriate depth in the wall using a drill bit with the diameter corresponding to the anchor bolts supplied with the water heater. Insert the bolts into the holes and tighten the bolt nuts firmly by turning the bolt hooks clockwise, then hang the water heater on the anchor bolt hooks (see Fig. 3,4).

Connecting to the water main

  1. The water heater must be connected to the water main with a minimum pressure of 0.1 MPa and a maximum pressure of 0.8 MPa.
    • NOTE!
    • The water heater is a product, in which water pressure corresponds to water pressure in the water main. If water pressure in the water main exceeds 0.8 MPa, a pressure-reducing valve must be installed before the heater to ensure that water pressure does not exceed 0.8 MPa.
  2. To connect the water heater to the water main, 12 mm (G1/2) diameter pipes are used.
  3. Use rubber seal gaskets on the threaded ends of the pipes in order to prevent leakage when connecting the pipes.
  4. Screw the safety relief valve on the inlet nozzle, which is marked in blue and has a water flow direction arrow in such a way that that the water flow coincides with the direction of the arrow on the valve body. Put the water drainage tube* (water may appear during heating) on the pressure relief port of the safety relief valve to allow water drainage into the sewer (see Fig. 6) (the tube must be directed downwards and must not be bent).
  5. Connect the heater with the mounted valve to the water main and install the shut-off valve at the water inlet point.
  6. Connect the required number of water consumption points to the outlet nozzle marked in red.
  7. Open the shut-off valve of the water main and one of the outlet valves. When the tank is full, which is prompted by water leaking from the outlet valve, close the outlet valve and make sure that all connectors are tight.
  • not included in the scope of delivery. New hoses must be used, old hoses must not be reused


  • Do not operate the water heater without a safety relief valve installed on the inlet nozzle.


  • The pressure-relief device must be activated on a regular basis to remove the scale and ensure proper operation.


  • A discharge pipe connected to the pressure relief device installed downwards direction and in a frost-free environment.


  • No additional accessories, such as a shut-off valve, must be mounted between the safety relief valve and the inlet nozzle.


  • If water in the installation place has significant content of calcium, manganese or iron salts, it is necessary to install a suitable filter in the water supply system in order to reduce the amount of scale in the tank and on the heating element.
    Connection to the electric main


  • Before connecting the tank water heater, make sure the water heater is properly grounded. Proper grounding is important to minimize electrocution and fire hazard. The power cord is equipped with a plug with a grounding contact. The product must be used with a properly grounded main socket.


  • Using a water heater without grounding is not safe for your life.
  1. The water heater is designed to be connected to a 220-240V~ single-phase electric main. Before connecting, make sure that the power supply at the site of connection complies with the parameters indicated on the plate with the specifications of the product. When installing the heater, comply with the applicable electrical safety precautions.
  2. The main socket must be designed for rated current of at least 10A and electric cable with core cross section of at least 3×1.5 mm2 (for copper).
  3. The plug and socket must be kept dry to avoid electrical leakage.


Install the electric socket in places or on walls that may be splashed with water at a height of at least 1.8 m.
Make sure that the electric plug is tightly connected to the socket on a regular basis. Check it as follows: insert the electric plug into the socket, turn off the water heater after 30 minutes of operation and remove the plug from the socket; check with your hand whether the plug is hot. If the plug is hotter than 50 °C, replace the socket to avoid damage, accidents, or fire due to poor electrical contact. Checks must be conducted by a specialist.

Water heater operation


  • First open one of the hot water outlet taps, after that open the cold water supply tap.
  • The electric water heater will start filling with water.
  • When water flows freely from the hot water tap, it means that the water heater is completely filled with water and the hot water outlet tap can be closed.
  • NOTE!
  • During normal operation, the cold water inlet tap must be in the “open” position.
  • Put the electric plug into the socket.

Setting the water heating temperature

  • The water heating temperature can be set within the range from +35 °C (±5 °C) to +75 °C (±5 °C) (the right-most position of the thermostat knob).
  • Turn the thermostat knob clockwise and set the desired water temperature.
  • Turn the thermostat knob counterclockwise to decrease the water heating temperature.
  • The water heater thermostat automatically maintains the water temperature. When the water temperature inside the water heater reaches the set temperature, heating is automatically turned off, the indicator light on the bottom of the device goes off and water temperature is maintained due to thermal insulation. Whenever water temperature drops below the set temperature, heating is automatically turned on and the indicator light comes on.
  • “ECO” mode, which corresponds to the temperature of ~ 58°C of heating the water in the tank.


  • Water may drip from the drain pipe of the pressure relief device, this pipe must remain unblocked.
  • Water dripping cannot be avoided and must not be prevented as blocking the valve can cause a rupture of the internal tank.
Turn off
  • To turn off the water heater, turn the thermostat knob to the left-most “OFF” position and unplug or disconnect the appliance from the power main.


  1. Check the electric plug and socket as often as possible. Ensure proper electrical contact and proper grounding. The plug and socket should not become excessively hot.
  2. If the water heater is not used for a long time, especially in regions with low air temperatures (below 0 °C), water must be drained from the heater to prevent damage to the product (to prevent water from freezing in the internal tank).
    • WARNING!
    • The manufacturer treats ay damage to the water heater done by water freezing in the internal tank as a non-warranty case.
  3. To ensure long-term reliable operation of the water heater and to maintain the manufacturer’s warranty, the internal tank must be periodically cleaned, and deposits must be removed from the heating element. Furthermore, the condition of the magnesium anode must be checked (degree of breakdown) in order to have it replaced with a new one in case of complete breakdown. Tank cleaning frequency depends on the hardness of water in the area.
    • WARNING!
    • The manufacturer offers an extended warranty on individual components of the water heater, provided that timely and proper maintenance is performed by specialists of the Authorized Service Center (ASC), see the warranty card.
  4. Preventive maintenance must be conducted in strict compliance with the operating manual and safety precautions.
  5. The heater is equipped with a thermal switch, which will disconnect power supply to the heating element if the water in the tank is overheated. If the IM2022
    water heater is plugged in, but the water is not heated and the indicator is not on, the thermal switch has either turned off or not been turned on. To reset the water heater back to operating condition, you must:
    • Disconnect power from the water heater, remove the bottom cover cap;
    • Press the button located in the center of the thermal switch (round shape, near the heating element) until you hear a click, see Fig. 7;
    • If the button cannot be pressed and there is no click, wait until the thermal switch cools to the initial temperature.
    • After resetting the thermal switch back to operating condition, perform the above steps in reverse order.
    • WARNING!
    • In case no positive effect has been achieved or the thermal switch turns off repeatedly within a short period of time, the power supply and water supply to the water heater should be disconnected, and your local ASC should be contacted for advice or product repair.
  6. To drain the internal tank, use the safety relief valve: unscrew the screw of drain knob on the safety relief valve and move the drain knob to the up position — the hot water outlet tap must be open and the cold water inlet tap must be closed (see Fig. 6). Water will start flowing from the pressure relief port of the safety relief valve.
    • WARNING!
    • Never drain water if its temperature is above 50 °C, as this may cause burns.
  7. Remember to check that the safety relief valve is operable every 14 days. Check it as follows:
    • move the drain knob to the up position until you feel the thread and then water should start flowing out of the pressure relief port. After checking the water flow, return the knob to the previous position.
    • WARNING!
    • If water does not flow, the valve is faulty. In this case, stop using the water heater and contact the service center.
  8. Clean the outer surfaces of the water heater with a damp cloth and soap as necessary.
