the connection point correspond to the
parameters indicated on the heater rating
plate.
When mounting the water heater, the
current electrical safety regulations have
to be observed.
When mounting the water heater in a
bathroom or a lavatory, the restrictions of
prohibited and protective areas should be
complied with.
Prohibited area is a space bounded by
tangential and vertical surfaces in relation
to the outer edges of the bathtub, toilet or
shower unit and a surface located above
them or above the floor, if the plumbing is
mounted on the floor, at a height of 2.25
m.
Protective volume is a space bounded
by horizontal surfaces coinciding with
the prohibited area surfaces, and the
vertical surfaces are 1 m apart from the
corresponding surfaces of the prohibited
area.

Operation

Water filling
Once the water heater is mounted, close
the hot water inlet to the apartment, open
the cold water supply valve. Open the
hot water tap on the mixer. As soon as
the water heater is full, water will flow
out, close the hot water tap on the mixer
and make sure there are no leaks. If you
are not sure if there is water in the water
heater, do not connect it to the power
supply network.

Precautionary measures

1. The power supply socket has to be reliably
grounded. The rated current of the socket
has to be at least 10 A. The socket and
plug have to be always dry to prevent
short circuits in the electrical network.

Check periodically that the plug is firmly
inserted into the outlet. The test method is
as follows: insert the power plug into the
socket outlet, in half an hour, turn the water
heater off and remove the plug from the
socket outlet. Check if the plug is warm to
the touch. If you feel with your hand that
it is warm (at temperatures above 50 °С),
please replace the socket with another
one where the plug fits firmly. This will
help prevent fire, plug damage or other
accidents due to poor contact.
2. The wall with the water heater mounted
has to be designed for a load twice the
total weight of the water heater filled with
water. Otherwise, additional measures
should be taken to support the product.
3. The safety valve should be mounted at the
water inlet (see figure 9).

4. When using the water heater for the first
time (or when using it for the first time after
maintenance or cleaning), do not switch
on the power of the water heater until it is
completely filled with water. While filling the
water heater tank, open the hot water tap
to release the air. As soon as the tank is
filled with water and water flows from the
tap, the tap can be closed.
5. When the water is heating, water may
come out of the pressure relief of the
safety valve. This is considered normal.
However, in the event of significant leaks,
contact the service technician. Under no
circumstances, the pressure relief should
be blocked; otherwise, it may damage the
water heater.
6. A drainage pipe has to be mounted on
the pressure relief hole in the safety valve
and led down to the drain in case of water
drain. The drainage pipe connected to the
pressure relief hole has to point downward.
