3. When installing and operating the EWH, it shall be forbidden to:
Connect the power supply if the EWH is not filled with water;
џ
remove the protective cover when the power is on;
џ
use the EWH without grounding or use water pipes as grounding;
џ
plug the EWH in the water supply system with a pressure of more than 0.6 MPa . If the pressure in
џ
the water supply system exceeds 0.6 MPa or is not stable and periodically exceeds 0.6 MPa , it is
necessary to install a suitable reducing valve (not included in the EWH supply package) at the inlet
of cold water in the EWH, in front of the relief valve (in the direction of water flow) in order to reduce
the pressure of cold water until it becomes normal. It shall be forbidden to install a pressure control
valve between the EWH and the relief valve;
connect the EWH to the water supply line without a relief valve;
џ
drain water from the EWH when the power is on;
џ
use spare parts not recommended by the manufacturer;
џ
use water from the EWH for cooking;
џ
use water containing mechanical impurities (sand, small stones) that can lead to the malfunction of
џ
the EWH and relief valve;
switch on and use the EWH with closed input and output valves (branch pipes).
џ
change the design and mounting dimensions of EWH brackets;
џ
4. Freezing of water in the device is unacceptable, as this leads to its failure, which is not a warranty
case.
5. The EWH is not intended for use by persons with reduced physical, tactile, or mental capabilities, or
by persons who cannot use the EWH, except when it is monitored or in accordance with instructions
from persons responsible for EWH safety. Children can use the EWH only under the supervision of
persons who know how to safely operate it. One shall always bear in mind that there is a risk of
scalding with water and electric shock.
6. If the buyer does not comply with Clauses 1 – 4 of this section, the manufacturer's warranty shall be
canceled.
7. It is not recommended to leave the EWH switched on in the power supply network in the absence of
supervision for more than 1 day.
Description and principle of operation
The EWH consists of casing, a heating element, a thermostat, a relief valve, and a protective cover
with control elements.
The EWH casing consists of a steel tank thermally insulated with environmentally friendly polyure-
thane foam and two threaded pipes: cold water inlet pipe (with a blue ring) and hot water outlet pipe
(with a red ring). The inner tank has a special glass-porcelain coating, which reliably protects the inner
surface from chemical corrosion.
The following components are mounted on a removable flange ( 3 ), Fig.1 : tubular heating element
(THE) ( 7 ), a thermostat ( 8 ), and a magnesium anode ( 9 ). The heater is used for heating water, and the
thermostat makes it possible to adjust the heating temperature to +74°C (± 5°C). The magnesium
anode is designed to neutralize the effects of electrochemical corrosion on the inner tank.
The water temperature in the inner tank is adjusted by means of the thermostat handle ( 10 ) located on
the protective cover of the water heater. The thermostat also contains a thermal switch
–
the device
protects the EWH from overheating, which disconnects the heater from the power supply network
when the water temperature exceeds + 93°С (±5°С). EWH may heat up during operation. The
activation of the thermal protection of the water heater is not its malfunction. To return the water heater
to the working state, press the thermoswitch rod located under the protective cover of the EWH
(
Fig. 2 ).
The relief valve functions as a non-return valve by preventing the water from entering the water pipe in
case of pressure drop in the latter and in case of increase in the pressure in the tank with strong water
heating and as a relief valve by relieving the overpressure in the tank when the water is heated up
strongly.
Depending on the EWH model, the protective cover ( 4 ) has one or two control lamps indicating the
instrument operation or power selection keys.
In models with a single control lamp, the lamp indicates the EWH operation mode – it is lit up when the
water is heated and goes out when the set temperature has been reached.
In models with two control lamps, the « Heating » Lamp indicates the EWH operation mode – it is lit up
when the water is heated and goes out when the set temperature has been reached. The « Power »
Lamp is lit up constantly – it indicates the device connection to the power supply network.
For models with power selection keys, the indicator of the EWH operation mode is used for the lamps
intended for highlighting power selection keys
– they are lit up when the water is heated and go out
when the set temperature has been reached.
Placement and Installation
It is advisable to install the EWH as close as possible to the place of use of hot water in order to reduce
heat losses in the pipes.
When selecting the installation site, the total weight of the EWH filled with water shall be taken into
account. The wall and the floor with a weak load-carrying capacity shall be strengthened, respec-
tively. When drilling (making) holes in the wall, it is necessary to take into account the cables,
channels, and pipes passing through it. The EWH is suspended using the casing brackets on the
anchor hooks fixed in the wall.
The manufacturer shall not bear responsibility for the EWH fall due to its incorrect installation.
The installation of hooks in the wall shall prevent the spontaneous movement of the EWH brackets
over them. For the purposes of EWH maintenance, the distance from the protective cover to the
nearest surface in the direction of the removable flange axis shall be at least 0.5 meters.
In order to avoid causing harm to the property of the customer and (or) third parties in case of faulty hot
water supply system, it is necessary to install the EWH in premises that are equipped with waterproof-
ing floors and drainage to the sewage system, and under no circumstances should you place non-
