TECHNICAL DESCRIPTION

The water heater is intended for domestic purposes in households,
and can provide hot water from the common water main system
simultaneously for a few consumers – kitchen, bathroom and etc.
The heated water should be correspond to the normative
documents for domestic water and, in particular: its composition of
chlorides should be less than 250 mg/l; the electrical conductivity
should be more than 100 µS/cm and pH=6,5-8 for the water
heaters with enameled water tanks; the electrical conductivity
should be less than 200 µS/cm for the water heaters with chrome-
nickel steel water tanks. The water pressure in the water supply
system should be higher than 0.1 MPa and lower than 0.5 MPa. If
the water pressure is higher than 0.5 MPa – please refer to the
instructions in the section for connection to the water supply
network. Special water heater models are in production (for
regions where local regulations require) with design to work in
plumbing pressure up to 1 MPa.
The appliances water containers of the appliances are properly
protected against corrosion by using high quality enameled
coating, or are made of high-range alloy chrome-nickel (corrosion
resistant) steel. Water tanks with enameled coating are equipped
with built-in anodes made of special alloy providing additional
protection.
The outer casing of the appliances is made of epoxy-polymer
coverage and the heat insulation is made of CFC-free
polyurethane foam.
Schematic views of the basic models with their modifications are
shown in Fig. 1-7, and their engineering characteristics – in Tables
1 and 1a. Please refer to all figures and tables in the manual.
The water heater models and their modifications are marked with a
number with additional letter and digit as follow:
The base model is marked only with a number – a water
Ÿ
heater with an enameled water container for vertical
installation, Fig. 1 and 1a.
"А" – in the enameled water tank is built-in an anode tester
Ÿ
indicating the level of corrosion protection and anode wear,
Fig. 1b.
"Н" - the water container of the appliance is made of chrome-
Ÿ
nickel steel alloy.
"Х" – the water heater may be installed only horizontally.
Ÿ
"UN" - water heater for universal installation, in vertical or
Ÿ
horizontal position.
"B" - the water heater for horizontal installation comes with a
Ÿ
set of brackets for mounting.
"S," "S2," "S21," and "T" - the water container is equipped
Ÿ
with built-in one or two heat exchangers for water heating
from an alternative heat source (local water heating, solar
collector and any other similar sources), Fig. 4 for "S" and
"S2," Fig. 5 for "S21" and Fig. 6 for "T". Water heaters with
heat exchanger designed for horizontal installation are
marked with additional combinations of letters, the main ones
being "XS," Fig. 7.
"R"–theoutletsoftheheatexchangerand/orthecold/hotwater
Ÿ
pipes on some modifications vertical and horizontal water
heaters are located on the right side of the mounted on the wall
appliance.
"L" – the cold/hot water pipes on some modifications of
Ÿ
horizontal water heaters are located on the left side of the
mounted on the wall appliance.
"D", "DC" – within the water heaters are built-in up to two
Ÿ
18
electric heaters located in special tubes on the tank flange. It
improves the appliance safety of the device while increasing
corrosion resistance. "D" – metal tube heating element, up to
1,6 kW for 30 and 50 l., up to 2 kW for 80 and 100 l. and up to
2,4 kW for the remaining. "DC" – ceramic heating element,
1,5 kW for 50 l. and up to 2.2 kW for the remaining.
"E" and "Ek" – water heater with heater digital control unit
Ÿ
("E") or in modification with heat exchanger - on both heater
and devices for coolant flow control ("Ek"), Fig. 1c. These
appliances are accompanied by additional instructions
describing how to use the digital control unit.
"G" (Fig. d) 1 , "GN" (Fig. h)
Ÿ
built-in switch, but has a signaling lamp.
"Q" (Fig. 1e) - the device operates with illuminated switch.
Ÿ
"W", "WG", and "WDG", "WNDG" – the water heater is with
Ÿ
new design of the shell. "W" - The appliance is equipped with
rocker switch (for turn on/ off of the heating element) and with
additional LED indication for operation of the heating
element. "WG" - the appliance is equipped only with LED
indication for the operation of the heating element. General
view of these modifications is shown in Fig 1f.
The electric power of water heaters (excluding those with letters
"D" and "DC") is 1,5 kW for 30 l, up to 2 kW for 50 l and up to 3 kW
for all others.
The exact and complete model number, nominal operating
parameters and serial number of purchased water heater are
marked on manufacturer plate affixed on its body.
Water heaters for vertical installation. These models of heaters
are designed for mounting only in a vertical position with cold and
hot water pipes downward, Fig. 1-1g.
Water heaters for horizontal installation. These models of
heaters are designed for mounting only in a horizontal position in
accordance with the schema designed for each model number,
Fig. 2, 3 and 10.
Water heaters for universal installation. These models water
heaters are designed for optional vertical (Fig. 1), or horizontal
installation (Fig. 3).
WARNING! When the water heater with universal installation is
mounted in a horizontal position IT IS MANDATORY that the
pipes for hot and cold water, and its electric control be on its left
side, see Fig. 3. Failure to do so will make the unit dangerous
and the manufacturer and / or the trader shall not assume any
responsibility for occurrence of any adverse effects and
damages!
Water heaters with heat exchanger. The water heaters of these
models secure an energy efficient operation thanks to their built-in
heat exchangers. The heat exchanger(s) outlets locations and
their basic installation distances are shown on Fig. 4, 5, 6, 7 and
Tables 2 and 2a. By using a heat exchanger bigger quantities of
water inside the water container can be heated through an
additional alternative energy source, i.e. local or central heating
system, solar collectors and other similar sources. For more
efficient heat exchanger use it is recommended to move the heat-
transfer liquid with a circulation pump. For
be used as well water with composition and parameters with
deviations within the permissible norms as defined in the
regulations concerning the water legislation. The heat-transfer
liquid must be with temperature not higher than 85 °С and in its
circuit must be installed a control device set at this temperature in
