3. When installing and operating the EWH, it shall be forbidden to:
EN
џ
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
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;
џ
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
the EWH and relief valve;
џ
switch on and use the EWH with closed input and output valves (branch pipes).
џ
change the design and mounting dimensions of EWH brackets;
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.
