Safety rules

Warning!
Do not use portable outlets. Improper instal-
lation and operation of the electric water
heater can cause accidents or property
damage.
• The power outlet must be securely ground-
ed. 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 cir-
cuit 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).
• 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,

Fig. 1
in the event of large leaks, contact a
service technician. The pressure out-
let 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 tem-
perature 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.
* 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.
