4. DESCRIPTION AND PRINCIPLE OF OPERATION
The outside casing of the EWH is made of impact-resistant plastic. The inner tank is
made of high-quality austenitic stainless steel, which provides high corrosion resistance
and long operating life. The space between the outside casing and the inner tank is filled
with polyurethane foam - a modern, ecologically clean thermal insulation, which has
the best heat-saving characteristics. IF PRO Wi-Fi models have two screwed nozzles:
for inlet of cold water (Figure 1, p. 3) with a blue ring and for outlet of hot water (Figure
1, p. 2) —with a red ring, and equipped with an additional drain connection (closed
with metal plug button) for draining the water and flushing the inner tank (Figure 1, p.
17). The control panel, in all models, is on the front side of the EWH. (Figure 1, p. 16).
Tubular heating element (THE), thermostat and thermal switch sensors are mounted
on the removable flange. THE is used to heat water and thermostat provides with pos-
sibility of heating temperature regulation up to +65°С. All models have electronic
control with sensor adjustment. Electronics maintain automatically water temperature
at the level set by the user. The thermostat is used for protecting against EWH over-
heating, which disconnects THE from power supply when water temperature exceeds
95°С. (Fig. 3).
Safety valve (Fig. 1, p. 5) operates as the check valve, ensuring protection of the water
ingress from the water heater into the sewage system in case of pressure drop in the
sewage system and in case of pressure rise in the tank at high water heating, as well as
the functions of the safety valve, releasing overpressure in the tank at high water heat-
ing. During water heater operation water may leak out of the exhaust outlet pipe of the
safety valve to relieve excessive pressure, which is made for the purpose of water
heater safety. This outlet pipe shall remain open to the atmosphere and be installed
constantly down.
Drainage of water from the safety valve exhaust pipe into the drain shall be pro-
vided with installation of the corresponding EWH drainage.
It is required regularly (at least once a month) to discharge a small amount of water
through the exhaust pipe of the safety valve into the drain to remove lime deposits and

to test the operating functionality of the valve. Handle (Fig. 1, p. 15) is intended to open
the valve. It is necessary to control when operating water heater this handle to be in
position closing water draining from the tank.
5. SPECIFYING SECURITY MEASURES
Electrical safety and corrosion protection of EWH are guaranteed only if there is an
effective grounding in accordance with applicable electric installation rules and regula-
tions.
Plumbing pipes and fittings shall conform to parameters of water main and have
the required certificates of quality.
When installing and operating EWH the following is not allowed:
•To power EWH if EWH is not filled with water.
•To remove the protective cover when the power is on.
•Use EWH without grounding or use water pipes as grounding.
•To connect EWH to water supply with pressure exceeding 0.7 MPa.
•To connect EWH to the water supply without safety valve.
•To drain water from EWH with power switched on.
•To use spare parts not recommended by the manufacturer.
•To use water from the EWH for cooking.
•To use water containing impurities (sand, small stones), which might lead to
EWH and safety valve breakdown.
•To modify design and installation dimensions of EWH brackets.
Ambient temperature shall be within the range of 3ºС to 40ºС. Water in freezing
EWH at negative temperatures results in malfunction, which is not a warranty case.
Attention should be paid to children so that they do not play with EWH.
EWH is not intended for use by persons (including children) with limited
physical, sensory or mental capabilities, or by persons who do not know
how to use the EWH, except for cases when this happens under the
supervision or instructions by persons responsible for safety of the EWH.
During EWH operation, it shall be inspected regularly for proper health (absence
of dripping, burning smell, wiring sparks, etc.). In the case of long interruptions in water
heater operation, water supply failures, EWH shall be disabled and cold water inlet
valve shall be shut off.

6. INSTALLATION AND CONNECTION
All installation, plumbing and electrical works shall be performed by qualified person-
nel.
7. ARRANGEMENT AND INSTALLATION
All installation, plumbing and electrical works shall be performed by qualified per-
sonnel.
EWH installation shall be performed in accordance with marking on the housing.
It is recommended to install EWH as close as possible to the place of hot water
using to reduce heat loss in the pipes.
When choosing the place of installation it should be taken into account the total
weight of EWH filled with water. Walls and floor with low carrying capacity should be
strengthened accordingly. When drilling (making) holes in the wall consider cables,
ducts and pipes in the wall.
EWH is suspended by brackets on hook anchors fixed in the wall. Hooks mounting
on the wall shall exclude spontaneous movement of EWH brackets along them.
The manufacturer bears no liability for EWH falling associated with improper in-
stallation of anchors and their selection.
For EWH maintenance the distance from the protective cover to the nearest surface
in the direction of the removable flange axis shall be at least 30 cm for all models.
In order to avoid damage of the user’s and/or third parties’ property in
the event of a faulty hot water system, it is required to install EWH in
spaces with waterproofing and drainage to the sewers, and in no case to
place under items exposed to the water under EWH. When placed in un-
protected areas a protective plate (not supplied) with drainage into sewers
shall be installed under the EWH.
In case of placing EWH in hard-to-reach places in order to perform maintenance
and warranty service (mezzanine floors, niches, ceiling voids, etc.), installation and dis-
mantling of EWH is carried out by the user on his own or for his own account.
Note: safety tray is not included into the scope of EWH supply.
8. CONNECTION TO WATER MAINS
Cold water shall be supplied to EWH using pre-filter with water treatment level not
less than 200 µm.

Install pressure relief valve (fig. 1, p.5) at the cold water inlet (fig. 1, p. 3) tube
with the blue ring, by 3.5-4 turnings, ensuring junction tightness with any sealing ma-
terial (flax, FUM tape, etc.).
During EWH operation you can observe water leak out of the outlet pipe of the
safety valve for excessive pressure release to ensure safety of the water heater. It is
recommended to connect to a drainage hole a rubber or silicone pipe of the relevant
diameter for moisture removal.
Connection to the water supply line shall be carried out in accordance with Fig. 1
using copper, plastic pipes or special flexible sanitary wiring. Do not use any used flex-
ible wiring. It is recommended to supply water to EWH through filter installed on the
cold water main (not included in the scope of supply).
Do not use used flexible feed pipes. Do not operate the EWH without
safety valve or with valve made by other manufacturers.
