This water heater has been manufactured in compliance with the relevant standards
and tested by the relevant authorities as indicated by the Safety Certificate and the
Electromagnetic Compatibility Certificate. The technical characteristics of the product are
listed on the label affixed between the inlet and outlet pipes. The installation must be carried
out by qualified staff. All repairs and maintenance work within the water heater, e.g. lime
removal or inspection/replacement of the protective anticorrosion anode , must be carried out
by the authorised maintenance service provider.
BUILDING-IN
The water heater shall be built-in as close as possible to the outlets. When installing the
water heater in a room with bathtub or shower, take into account requirements defined in IEC
Standard 60364-7-701 (VDE 0100, Part 701 ). It has to be fitted to the wall using appropriate
rag bolts with minimum diameter of 8 mm. The wall with feeble charging ability must be on
the spot where the water heater shall be hanged suitably reinforced. The water heater may
be fixed upon the wall onlyvertically.

The water heater connections forthe in-flowing and out-flowing water are colour-coded. The
connection for the supply ofcold water is coloured blue, while the hotwater outletis coloured
red.
The water heater may be connected to the water supply in two ways. The closed-circuit
pressure system enablesseveral points of use, while the open-circuitgravity system enables
a single point of use only. The mixer taps must also be purchased in accordance with the
selected installation mode.
The open-circuit gravity system requires the installation of a non-return valve in order to
prevent the water from draining out
of the tank in the event of the water supply running dry
or being shut down. This installation mode requires the use of an instantaneous mixer tap.
As
the heating ofwater expands its volume, this causes the tap to drip. The dripping cannot
be stopped
by tightening it further; on the contrary, the tightening can only damage the tap.
The closed-circuit pressure system requires the use of pressure mixer taps. For safety
reasons the supply pipe must be fitted with a return safety valve
or alternatively, a valve of
the safety class that prevents the pressure in the tank from exceeding the nominal pressure
by more than
0.1 MPa. The outletopening on the reliefvalve must be equipped with an outlet
for atmospheric pressure.
The heating of water in the heater causes the pressure in the tank to increase to the level set
by the safetyvalve.
As the water cannot return to the water supply system, this can result in
the dripping from the outlet of the safetyvalve. The drip can be piped to thedrain by installing
a catching unit just below the safety valve. The drain installed below the safety valve outlet
must be piped down vertically and located in the environment that is free from the onset of
freezing conditions.
In case the existing plumbing does not enable you to pipe the dripping water from the return
safety valve into the drain, you can avoid the dripping by installing a 3-litre expansion
tank
on the inlet water pipe of the boiler.
In order to provide correct operation of
the relief valve, periodical inspections of the relief
valve must be carried
out by the user. To checkthe valve, you should open the outlet of the
return safety valve by turning the handle
or unscrewing the nut of the valve (depending on
the type of the valve). The valve is operating properly if the water comes out of the nozzle
when the outlet is open.

Between the water heater and return safety valve no closing valve may be built-in
because with it the function of return safety valve wou Id be impeded.
The water heater may be connected to the water network in the house without reduction
valve if the pressure in the network is lower than 0.5 MPa (5 bar). If the pressure exceeds
0.5 MPa (5 bar), a reduction valve must be installed. Prior to the electric connection the
water heater must obligatorily be filled with water. By first filling thetap forthe hotwater upon
the mixing tap must be opened. When the heater is filled with water, the water starts
to run
through the outlet pipe ofthe mixing tap.
CONNECTION OF THE WATER HEATER TO THE ELECTRIC NETWORK
Before connecting to power supply network, install a power supply cord in the water heater,
with a min. diameter of 1,5 mm2 (H05VV-F 3G 1,5 mm2
). For it the protection plate must be
removed from the water heater.
The connection of water heater
to the electric network must be performed according to
standards for electric installation. Install a disconnect switch (separating all poles from the
power supply network) between the water heater and the permanent power connection,
in
compliance with the national regulations.

OPERATION AND MAINTENANCE
After connecting to water and power supply, the heater is prepared for use.
The water heater features
an that enables of watertemperature of in water heater tank. The
electronic regulator allows manual adjustment of temperature in range from 35°C to 75°C,
settings to cost saving operation mode and temperature adjustment to preventfreezing.
Electronic regulator display shows the current temperature of water in water heater.
OPERATION CONTROL:
The heater is switched ON and OFF by pressing the ~ key for 2s.
Continue pressing the @ key and select the three operating modes:
-
~protection against freezing (factory water temperature set to 7°C)
ecost saving operation (factory set to 55°C)
- ~optional manual setting oftemperature in the range from 35°C to 75°C (increments of

VVhen the water heater is not in use for longer periods of time, it should be protected from
freezing by setting thetemperature to"*". Do not disconnectthe power. Thus thetemperature
of water is maintained at about 10°C. Should you choose to disconnect the power, the
water heater should be thoroughly drained before the onset of freezing conditions. Water is
discharged from heater via the inlet pipe. To this purpose, a special fitting (T-fitting) must be
mounted between
the relief valve and the heater inlet pipe, or a discharge tap. The heater
can be discharged directly through the relief valve, by rotating the handle or the rotating
valve cap to same position as for checking the operation. Before discharge, make sure
the heater is disconnected from the power supply , open the hot water on the connected
mixer tap. After discharging through the inlet pipe,
there is still some water left in the water
heater. The remaining water will be discharged after removing the heating flange, through
the heating flange opening.
The external parts of the water heater may be cleaned with a mild detergent solution. Do not
use solvents and abrasives.
Regular preventive maintenance inspections ensure faultless performance and long
life
of your heater. The first of these inspections should be carried out by the authorised
maintenance service provider
about two years from installation in order to inspect the
wear of the protective anticorrosion anode and remove the lime coating and sediment as
required. The lime coating and sediment on the walls of the tank and on the heating element
is a product of quality, puantity and temperature of water flowing through the water heater.
The maintenance service provider shall also issue a condition report and recommend the
approximate date
of the next inspection.
Never try to repair any possible faults of the water heater by yourself, but inform
about it the nearest authorised service workshop.
