EN
I. Intended use
The appliance is intended to supply hot wa-
ter to household sites equipped with a pip-
ing system working at pressure below 7
atm. (0,7 Mpa).
The appliance is intended for work in
closed, heated premises and is not intend-
ed to work in a constant flow through
regime.
II. Technical parameters
1. Nominal volume V, liters - see the ap-
pliance's rating plate
2. Nominal voltage - see the appliance's
rating plate
3. Nominal power consumption - see the
appliance's rating plate
4. Nominal pressure - see the appliance's
rating plate
5. Water heater type - closed type accu-
mulating water heater, with thermal
insulation
6. Inner coating - for models: GC-glass-
ceramics; SS-stainless steel; EV -
email
7. Water temperature after turning off of
the thermostat: from 60°С to 75°С.
Important: For models with a regulated thermo-
stat, the specified temperature range refers to
the cases when the thermostat is set at maximum
water heating temperature (see below).
III. Description and principle
of work
The appliance consists of a body, flange
at the bottom side /for water heaters in-
tended for vertical mounting/ or at the
sides /for water heaters intended for
horizontal mounting/, protective plastic
panel safety-return valve.
1.1 The body consists of a steel reservoir
(water tank) and housing (outer shell)
with thermal insulation placed in-be-
tween made of ecologically clean high
density polyurethane foam, and two
Εlectric water heater | 13
pipes with thread G ½ '' for cold water
supply (marked by a blue ring) and hot
water outlet pipe (marked by a red ring).
The inner tank may be of two types de-
pending on the model:
Made of steel protected form corrosion
by a special glass-ceramics coating
Made of stainless steel
The vertical water heaters may be outfit-
ted with a built in heat exchange unit
(boiler tube). The boiler tube's entrance
and exit are located at the sides and rep-
resent pipes with thread G ¾ ''.
1.2 The flange is outfitted with: electric
heater and thermostat. The water heat-
ers with glass-ceramics coating are out-
fitted with a magnesium protector.
The electric heater is used for heating
the water in the tank and is managed by
the thermostat, which automatically
maintains the set temperature.
The thermostat has a built in overheating
safety device, which switches of power
to the heater when the water tempera-
ture reaches excessive values. In the
event this device is tripped, please con-
sult a service station.
1.3 The safety-return valve prevents the
appliance's complete emptying in the
event the cold water supply is interrupt-
ed. The valve protects the appliance
from pressure increases higher than the
allowed value during heating (! pressure
increases upon an increase of tempera-
ture), via release of excess pressure dur-
ing the drainage opening.
ATTENTION! The safety-return valve
cannot protect the appliance in the
event of water mains pressure in ex-
cess of the acceptable pressure stat-
ed for the appliance.
