placed support washers! A drilling hole template is
printed on the product packaging.
The installation site must comply with the require-
ments of the electrical installation. During installa-
tion, provide sufficient distance to adjacent walls
and sufficient space under the unit for the water
and photovoltaic connections.
CONNECTION TO THE WATER
SUPPLY
When connecting the device to the water supply,
please observe the indicated arrows and rings
around the cold and hot water pipes (supply and
return pipes). The cold-water pipe features a blue
ring and is marked with an arrow pointing towards
the pipe. The hot water pipe is indicated by an arrow
pointing out of the pipe and a red ring.
The water heater is equipped with a combined check
and pressure relief valve, which is included in the
product packaging and
cold-water pipe. The arrow on the body of the valve,
which indicates the direction of water flow through
the valve, must be followed during this installation.
WARNING! The absence or improper installation
of the combined valve supplied with the product is
grounds for voiding the product warranty.
WARNING! It is FORBIDDEN
shut-off fittings between the combined valve and the
water heater! It is absolutely forbidden to obstruct
the lateral opening of the combined valve and/or
to block its lever!
The pipe connectors have male G½ threads.
The water heater operates by the pressure of the
water pipe. The water pressure of the water supply
system should be higher than 0,1 МРа (1 bar) and
lower than 0,5 МРа (5 bar). If the pressure of the
water pipe exceeds 0,5 MPa, a pressure reducing
valve must be installed.
If additional equipment, which is not included in
the standard delivery, must be used to comply with
local regulations, they must be installed according
to these specifications.
In case the water pipes are made of copper or other
metal which differs from the metal of the water tank,
MUST be installed on the
to install any kind of
as well as if connecting elements made of brass are
used, non-metal fittings must be installed on the
supply and return side of the water heater (dielec-
tric fittings).
WARNING! The installation of any shut-off or non-
return fittings between the pressure relief valve and
the water heater, as well as blocking the side opening
of the pressure relief valve and/or locking its lever
is prohibited!
A drainage system to remove any water that may
drip from the side opening of the pressure re-
lief valve is recommended. The drain line must
be designed with a constant downward slope in
a frost-free environment and must remain open.
After connecting the water heater to the water sup-
ply, fill the tank with water. The sequence of steps
to be performed is:
• Fully open the hot water tap of the most distant
mixing tap.
• Open the shut-off valve. (Table 1, No. 4)
• Wait until the air is released from the system and
a strong jet of water flows from the mixer tap.
Let the water run for about 30 seconds.
• Close the hot water tap of the mixer tap.
• Lift the small lever of the pressure relief valve
(Table 1, No. 5), wait 30-60 seconds until a strong
stream of water flows out of the side opening
of the valve.
• Loosen the valve lever.
WARNING! If no water or only a thin stream of wa-
ter flows out of the valve opening, this indicates a
malfunction. A possible contamination of the water
pipe might be present. The fault must be eliminated
before the unit is put into operation.
IT IS FORBIDDEN
tric connection before eliminating the reason for
malfunction!
WARNING! Failure to comply with the requirements
for connection to the water supply system may cause
partial filling up of the water tank and malfunction of
the heating element, or when the combined valve is
not installed at all or has been improperly installed
this may even cause destruction of the water tank,
the room and/or other damages to tangible and in-
tangible property. Such consequences are not within
the scope of manufacturer or seller warranty liabili-
ties and shall be at the expense of the party, which
