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 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. 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 (water tanks) 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 technical specifications – in Tables 1, 1a, 2 and 2a. All figures
and tables are located at the beginning of this booklet.
The water heater models are marked with letters and digits as follow:
џThe first two letters and the following five digits indicate the device
base model.
џ„W“/„S“ – the devices are designed for premise wall mounting.
џ„V“ – the water heater can be installed only in a vertical position.
џ„H“ – the water heater can be installed only in a horizontal position.
џ„U“ – the water heater is with a universal mounting - can be installed in
a vertical or in a horizontal position.
џxxx – the first three digits after the letters „V“, „H“ or „U“, are code for
the water tank capacity range of the water heater.
џyy – the next two digits are code of the device diameter.
џ„А“ – in the enameled water tank is built-in an anode tester indicating
the level of corrosion protection and anode wear, Fig. 1а, pos. 6
џ„I“ – the water tank of the appliance is made of chrome-nickel steel
alloy.
џ„S“, „S2“, „S21“ and „Т“ – in the water heater are 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 „Т“. Water heaters with a
heat exchanger designed for horizontal installation, are shown in
Fig.7.
џ„L“ – the outlets of the heat exchanger and/or pipes for cold and hot
water of some vertical and horizontal water heaters are located on the
left side of the wall-mounted unit.
џ„R“ – the outlets of the heat exchanger and/or pipes for cold and hot
water of some vertical and horizontal water heaters are located on the
right side of the wall-mounted unit.
џ„B“ – the outlets of cold/hot water pipes of horizontal water heaters are
located below of the wall-mounted unit.
џ„D“, „C“ – within the water heaters are built-in up to two electric heaters
located in special tubes on the water tank flange. It improves the
appliance safety of the device while increasing corrosion resistance.
"D" - with tubular metal heating element, to 1,6 kW for units with a
capacity up to 50 l (volume groups 30 and 50), up to 2 kW for units with
a capacity of up to 100 l (vol. groups 80 and 100) and up to 2,2 kW for
all others. "C" - with ceramic heating element, 1,5 kW for units in
volume group 50, and up to 2,2 kW for the remaining.
џ„Е“, „Еxy“ – the water heater is equipped with electronic control unit for
the heater or for water heaters with heat exchangers - for the heater
and the devices for coolant flow control, Fig. 1b. These appliances are
accompanied by additional instructions describing how to use the
digital control unit.
џThe units with model numbers 722xxW(WN;WG;WNG;
WD;WND)/SVxxxyy have a reshaped design of the lower cover and
control, Fig. 1+1c/1+1d.
The hot and cold water pipes are marked with colored pointers, respectively
red and blue.
The water heater power (excluding those with letters "D" and "C") is 1,5 kW
for the units in volume group 30, up to 2 kW for the units in group 50 and 3 kW
for the rest.
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 Fig. 4-6.
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 Fig. 3 Fig. 7
Water heaters for universal installation. These models water heaters are
designed for optional vertical (Fig. 1), or horizontal installation (Fig. 2).
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. 2. 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 heat-transfer liquid can be used water with
composition and index values within the levels laid down in the regulations
related to water or a dedicated aqueous solution which is not aggressive to
heat exchanger material. 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 order not to allow thermal cut-out of the electrical
heating element during normal operation. The pressure of the heat-transfer
liquid in the heat exchangers must not exceed the stated working pressure
of the heater.
WATER HEATER INSTALLATION ON THE WALL
OF THE PREMISE
The water heater can be installed only in normal fire safeguarded premises
and where temperature cannot fall under 0 °C. The availability of a siphon
on the installation for waste waters as during normal usage of the water
heater, 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.
