Safety rules
Warning!
Do not use portable outlets. Improper
installation and operation of the electric
water heater can cause accidents or property
damage.
• The power outlet must be securely
grounded. The rated current of the power
outlet must be at least 10 А. Keep the socket
and plug dry at all times to prevent a short
circuit in the electrical system.
• The wall on which the water heater is
installed must be rated for twice the total
weight of the water heater filled with water.
• A safety check valve should be installed at
the cold water inlet (see Fig. 1).
Fig. 1
• When using the water heater for the first
time (or when using it for the first time after
maintenance or cleaning), do not power
up the water heater until it is full. The hot
water tap should be opened while filling the
water heater tank. While filling the tank of
the water heater, open the hot water tap to
bleed air. As soon as the tank is filled with
water and water flows from the tap, the tap
can be closed.
• During water heating, water may
come out of the pressure relief vent of
the safety relief valve. This is normal.
However, in the event of large leaks,
contact a service technician. The
pressure outlet must never be blocked
under any circumstances;
Otherwise it may cause the water heater
to malfunction.
• The pressure vent on the pressure relief
valve (item 3 in Fig. 5) Install a drain tube
and lead it to the sewer in case water
is drained and excessive pressure is
relieved*. The drain tube connected to the
pressure outlet must point downward.
• The water temperature inside the water
heater can reach up to 75 °C. To avoid
scalding, you can adjust the water
temperature using the mixer tap.
Water Drain:
The water heater must be completely
drained if it will not be used for a long time
or if the temperature in the room where it is
installed may drop below 0 °C. Drain can be
carried out with the safety valve and there
may be leakage under the valve stem.
A tee can be provided for the drain with
a valve between the valve and the sleeve
(item 1, fig. 5).
Before draining the water heater, don't
forget:
• Disconnect the power supply from the
device.
• Make sure that the water inside the tank is
at a safe temperature.
• Close the cold water supply to the tank
by closing the stop valve.
• Shut off the hot and cold water supply
water to the apartment.
• Open the hot water supply to the mixer to
relieve the pressure inside the tank.
• Open the shutoff valve on the tee fitting
on the hot water outlet of the water
heater (if a tee fitting has been installed),
Otherwise, dismantle the connection pipe
at the water heater outlet.
• Connect the drain hose (item 3 in Fig. 5)
to the shutoff valve.
• At the tee on the cold water inlet to the
water heater and direct it into the sewer,
or into the place where the water drains.
• Open the stopcock and wait for the water
to drain completely.
ENGLISH
* The water expands when heated, which increases the pressure in the water
heater. Always use a safety valve to prevent damage to the water heater.
