supply, it is necessary to install the appliance in
premises fitted with floor hydro-insulation and(or)
draining to the sewerage .Do not ever place water
non-resistant objects under the appliance. When
installing the appliance in rooms without
hydro-insulation on the floor, it is necessary to place
protective vat underneath with an option for
draining to the sewerage.
Note: the protective vat is not included in the set and is
selected by the consumer.

Connection of the water heater to the water supply
system (fig.2)
The appliance has to be connected to the water system for
supply of cold water with a pressure not lower than 1.5 bar
(0.15 MPa) and not higher than 6 bar (0.6 MPa).
If the pressure in the water supply system is over 0.6MPa
(6 bars), PRESSURE REDUCING VALVE has to be installed in
the water supply system before the appliance. The pressure
reducing valve is not included in the set of the appliance!
It is not allowed to use the appliance in systems
with preliminarily heated water. The highest
allowed temperature at the inlet of the appliance
is 20°С.
The resistance of water cannot be lower than the value
given on the nameplate of the appliance.
2.1.
Models for the kitchen
– fig. 1
It is not allowed to use connecting fittings that are
not from the manufacturer or have not been agreed
upon with them.
The thread at the inlet of the mixing tap (included in the
set) is ½”. The tap is directly connected to the water supply
system and the appliance is installed to it- see item 1.1
above.
After connecting the appliance and before switching on
the power, open the hot water tap until a constant water

Models for the bathroom
– fig. 2
The incoming and the leading-out pipes of the appliance
have R1/2” fastening thread.The inlet and the outlet are
indicated by arrows on the back lid of the appliance (or on
the tubes themselves). The arrows show the direction of
the water flow.
The cock for running, control and stopping of the water
flow is connected to the inlet of the appliance. It can be
installed directly on the incoming pipe of the water heater
or at a distance via a flexible hose (not included in the set)
when necessary.
The flexible hose of the shower head is directly connected
to the outlet of the appliance.
IMPORTANT! These models are open type (with
nominal pressure of 0 Pa). It is not allowed to shut the
hot water outlet via a stop cock or other types of isolating
fittings! It has to always be open to the atmosphere (these
models contact the atmosphere via the shower head and the
flexible hose)!
After connecting the appliance and before turning on the
electric supply, open the tap until steady jet of water starts
running from the shower head!
2.3.
IN LINE models
– fig. 5
The incoming and the leading-out pipes of the appliance
have R1/2” fastening thread.The inlet and the outlet are
indicated by arrows on the back lid of the appliance (or on
the tubes themselves). The arrows show the direction of
the water flow.
These models are designed as a closed type(pressurized).
The cock for running, control and stopping of the water
flow is installed after the appliance.
It is not allowed to install any back valves and closed
isolating fittings in the water system before the appliance.
The appliance can be connected to more than one hot
water point of use.
The water heater cannot supply enough hot water in
cases of simultaneous consumption from two points
of use!
After connecting the appliance and before switching the
power on, open the hot water tap until a steady water jet
starts running!
3.
Connection to the electricity grid
The appliance has to be earthed!
Do not switch on the power of the appliance before
making sure that it is full of water!
3.1.
Water heater fitted with supply cord and a plug
•
the plug has to be plugged in to a properly connected
and earthed socket.
•
the socket has to be connected to a separate electrical
circuit supplied with a safety fuse. The section of the
supply conductors and the nominal power of the
safety fuse have to conform with the data given in
Table 1
•
The verification of the fulfillment of the
abovementioned requirements shall be carried out by
a qualified technician (see item IV)
•
The appliance shall be placed in a position allowing
access to the socket of the supply cord.
