DESCRIPTION AND PRINCIPLE OF WORK
The appliance consists of a boiler shell, a flange at its lower
end /with vertically-installed boilers/ or lateral flange/with
horizontally-installed boilers/, protective plastic panel and
non-return safety valve.
The body consists of a steel reservoir (water tank)
1.
and housing (outer shell) with thermal insulation placed
in-between made of ecologically clean high density
polyurethane foam, and two pipes with thread G ½ '' for cold
water supply (marked by a blue ring) and hot water outlet
pipe (marked by a red ring).
The inner tank may be of two types depending on the model:
•
Made of steel protected form corrosion by a special glass-
ceramics coating
•
Made of stainless steel
The vertical water heaters may be outfitted with a built in
heat exchange unit (boiler tube). The boiler tube's entrance
and exit are located at the sides and represent pipes with
thread G ¾ ".
The flange is outfitted with: electric heater and
2.
thermostat. The water heaters with glass-ceramics coating are
outfitted with a magnesium protector.
The electric heater is used for heating the water in the tank
and is managed by the thermostat, which automatically
maintains the set temperature.
The thermostat has a built in overheating safety device, which
switches of power to the heater when the water temperature
reaches excessive values.
The safety-return valve prevents the appliance's complete
3.
emptying in the event the cold water supply is interrupted.
The valve protects the appliance from pressure increases
higher than the allowed value during heating (! pressure
increases upon an increase of temperature), via release of
excess pressure during the drainage opening
Attention! The safety-return valve cannot protect the
appliance in the event of water mains pressure in
excess of the acceptable pressure stated for the
appliance.

MOUNTING AND SWITCHING ON
Attention! Qualified technicians must perform all
technical and electrical assembly works. A qualified
technician is a person who has the competence
according the regulations of the country in question.
Mounting
1.
We recommend the mounting of the device at close
proximity to locations where hot water is used, in order to
reduce heat losses during transportation. In the event the
device is mounted in a bathroom, the selected location
must exclude the possibility of water spray contact from
the showerhead or portable showerhead attachment. Two
methods of installation are possible:
•
Vertical installation (fig. 1a) – When installing the appliance
onto a wall – the boiler should be hanged through the upper
carrying plank which is fixed to the boiler shell.
Two hooks are used for suspending the appliance (min. Ø
10 mm) set firmly in the wall (not included in the mounting
set). The mounting bracket's construction designed for water
heaters intended for vertical mounting is universal and allows
a distance between the hooks of 220 to 300 mm.
•
Horizontal installation GCHV and GCH models (fig.2а and
fig.2b) – At horizontal installation the distances between the
carrying hooks are different with the different capacities and
these values are indicated in table 2 to fig. 2a and fig. 2b.
Warning! The appliance must be installed in such a
way, so as the protective plastic panel and the inlet/
outlet pipes to remain on the left side of the boiler
(frontal view). The cold water supply pipe (with a blue
ring) must be beneath the hot water discharge pipe
(with a red ring).
Attention! In order to prevent injury to user and third
persons in the event of faults in the system for
providing hot water, the appliance must be mounted in
premises outfitted with floor hydro insulation and
plumbing drainage. Don't place objects, which are not
waterproof under the appliance under any
circumstances. In the event of mounting the appliance
in premises not outfitted with floor hydro insulation, a
protective tub with a plumbing drainage must be
placed under the appliance.
Notice: the set does not include a protective tub and the
user must select the same.
