TECHNICAL DESCRIPTION
The water heater is intended for use only for domestic purposes in
the household and is used to heat water from common water
supply network, which composition and features comply with the
specified values in water quality legislation, such as its chlorides
composition should be less than 250 mg/l and its electric
conductivity should be more than 100 µS/cm, while its pH within
the limits of 6.5-8 for the water heaters with enameled water tanks,
and electric conductivity less than 200 µS/cm for the water heaters
with chrome-nickel steel water tanks.
W
ater heaters are working with contained therein under pressure
water.
W
ater heaters are equipped with combined return valve,
which prevents runtime water pressure to exceed exposure limits.
W
ater heaters are manufactured with corrosion protection of the
water container - steel with durable enamel coating and an
additional cathodic protection of anodes with special alloy. In
production are as well modifications with the anode status
indicator - anode tester ( "A").
T
he thermal insulation of the water container is of foamed
polyurethane.

T
he parameters of basic water heaters with enameled water tank
are recorded in the table.
INSTALLATION OF THE WATER HEATER ON THE
WALL OF THE PREMISES
T
he water heater can be installed only in normal fire safeguarded
premises and where temperature cannot fall under 0°C. For water
heaters under pressure the availability of a siphon on the
installation for waste waters or another system of the same
purpose is needed, as during normal usage water may leak from
the safety valve aperture. At the same time the siphon will facilitate
the water tank maintenance, prevention and servicing operations
when water needs to be drained out of the water tank.
W
hen choosing a place of installation the dimensions of the
device, its security from dripping water, method of attachment and
connection to water and electricity installations are taken into
account.
WARNING!
The water heater is equipped with a power cord
with plug and can
NOT
be installed in a room for bathing!
I
n the water heater packaging is placed a suspension plate (Fig.
3
)
and 3 pcs. screws and dowels for concrete. With two of the dowels
and screws fasten the hanging plate securely to the wall of the
room. The location of the plate is selected so as to provide
sufficient space for the device and the fittings thereof, and its water
and electrical connections. The wall must be of sound and dense
material (such as concrete). It is unacceptable for hanging the unit
on decorative walls or made of hollow material. Once the plate
suspension is mounted, then the tank is hung on it. For this
purpose on the
device rear side there are provided holes. After the
suspension of the appliance using the third set dowel and screw fix
the unit rigidly to the wall through the opening of the ear of its hull,
located to the side of the cover with the management bodies - see
Figures 1- .

WARNING!
Failure to comply with these requirements may
result in damage to the device, other devices and the room in
which the appliance is installed. In these cases, such damages
are not covered by the warranty obligations of the manufacturer
and the seller.

ith an arrow towards the pipe and blue color is marked the cold
water pipe and with an arrow from the pipe and red color insert - the
hot water pipe.
WARNING!
IT IS MANDATORY in the cold water to the unit to
be mounted the supplied combined return valve and to keep the
arrow on the valve body indicating the direction of flow through
water flow.
IT IS PROHIBITED
to mount any valve between the combined
valve and the water heater! It is absolutely forbidden to block
the side hole of the combined valve!
T
he connection of the water heater under pressure

carried out in accordance with Fig.

.
T
he connection of the water heater under pressure

IT
IS FORBIDDEN
to
install the combined valve in the space
above the unit!
Where the plumbing pipes are copper or of another metal, other
than that of the water tank, or where brass fasteners are used,
it is
obligatory
to install on the water tank inlet and outlet non-metallic
couplings (dielectric fittings).
F
illing the water tank of the unit under pressure is carried out in the
following sequence: open the shut-off valve in the cold water pipe;
open the shut-off valve of the hot water mixing battery; wait until
the water flow is strong and solid; close the tap and hot water; lift
the lever of the combined valve and wait 30-60 seconds of the
lateral opening of the valve to flow thick and strong jet of water;
then relax the valve lever.
WARNING!
If no water is coming out of the opening of the
combined valve or the flow is weak (during normal water
pressure), this should be considered as a malfunction indicating
that impurities from the plumbing or caused by sewage
connections have blocked the safety valve of the combined
valve. IT IS FORBIDDEN to proceed with appliance electric
connection before eliminating the reason for malfunction.
I
f necessary you may make a system for draining dripping water
from the combined valve side hole. The drain pipe must have
constant downward slope and located in anti-freezing
environment with extremities in the atmosphere.
WARNING!
Failure to comply with the requirements for
connection to the water supply system may cause partial filling
up of the water tank and malfunction of the heating element, or
when the combined valve is not installed at all or has been
improperly installed this may even cause destruction of the
water tank. Such consequences are not within the scope of
manufacturer or seller warranty liabilities and shall be at the
expense of the party, which has not observed the present
manual instructions.
