The manufacturer reserves the right to change the design and characteristics of the water heater
without prior notice.
Information on the place of application and the method of determining the date of
manufacture:
The release date of the product is encoded in a unique serial number located on the nameplate (label)
at the bottom of the product case. The serial number of the product consists of thirteen digits. The third
and fourth digit of the serial number is the year of manufacture, the fifth, sixth is the month of
manufacture, the seventh, and eighth is the day of the manufacture of the EWH.
Safety precautions
1. All installation, plumbing and electrical work must be carried out by qualified personnel
only!
2. Electrical safety and anti-corrosion protection of the EWH are guaranteed only if there is an
effective grounding performed in accordance with the current Electrical Installation Code (EIC).
3. When installing and operating the EWH, the following is prohibited:
to connect the power supply if the EWH is not filled with water;
џ
to remove the cover when the power is on;
џ
to use the EWH without grounding or use water pipes for grounding;
џ
to connect the EWH to water supply system with a pressure of more than 0. 7 MPa . If the pressure in
џ
the water main exceeds 0. 7 MPa , or is not stable and periodically exceeds 0. 7 MPa , then at the inlet

of cold water to the EWH, upstream the safety valve (in the direction of water flow) it is necessary to
install a suitable pressure relief valve (not supplied with the EWH) to reduce the pressure of cold
water to normal. Installation of a pressure relief valve between the EWH and the safety valve is
prohibited;
to connect the EWH to the water supply without a safety valve;
џ
to drain the water from the EWH when the power is on;
џ
to use spare parts not recommended by the manufacturer;
џ
to use water from the EWH for cooking;
џ
to use water containing mechanical impurities (sand, small stones), which can lead to malfunction
џ
of the EWH and safety valve;
to switch on and operate the EWH with closed inlet and outlet valves (nipples).
џ
to change the design and mounting dimensions of the EWH brackets;
џ
4. Freezing of water in the device is unacceptable, as this leads to its malfunction, which is not a
warranty case.
5. The EWH is not intended for use by physically or mentally challenged persons, or by persons who
are unable to use the EWH, except when it is monitored or instructed by persons responsible for the
safety of the EWH. Children can use the EWH only under the supervision of persons who know how to
safely operate it. It is necessary to remember that there is a risk of scalding and electric shock.
6. If the purchaser does not comply with clauses 1–4 of this section, the manufacturer's warranty will
be voided.
7. Violation of the rules of the fire prevention regime in the Russian Federation, approved by
Government Resolution No. 390 of April 25, 2012, may lead to harm to life and health of a person, as
well as property.
8. During the operation of the EWH, it is necessary to regularly inspect the device for correct
operation (no smudges, smell of burning, sparking wires, etc.). In the event of long breaks in the
operation of the water heater, failures in the operation of water supply or electricity supply systems, it
is necessary to disconnect the EWH from the mains and close the cold water supply valve
.
Description and functioning
The inner tank is made of high quality stainless steel, which provides high corrosion resistance and,
consequently, long service life. The space between the outer case and the inner tank is filled with
polyurethane foam – a modern, ecologically clean thermal insulation, which has the best heat-saving
characteristics. The EWH has two threaded nipples: for cold water inlet (
Fig. 1, item 3 ) with the blue
ring and hot water outlet ( Fig. 1, item 2 ) with the red ring.
The control panel is located on the protective cover ( Fig. 1, item 16 ).
A tubular electric heater, thermostat, and temperature switch sensors are mounted on the removable
flange. The tubular heater is used for heating water and is controlled by the thermostat, which has a
smooth temperature control of up to +74 °C (±5 °C). The thermostat automatically maintains the water
temperature at the level set by the user. The temperature control knob is located on the protective
cover (
Fig. 1, item 17 ).
The temperature switch serves to protect the EWH from overheating and disconnects the tubular
heater from the mains when the water temperature e93 °C (+15/–5 °C).
An indicator lamp ( Fig.1, item 18 ), which is an indicator of the heating of water in the EWH, is located
on the front side of the EWH. If the indicator lamp is on, the water is heating up, and the lamp is off
when the temperature set by the customer is reached.
