DESCRIPTION AND PRINCIPLE OF WORK
EN
The appliance consists of a body, flange at the bottom
side /for water heaters intended for vertical mounting/
or at the sides /for water heaters intended for horizontal
mounting/, protective plastic panel safety-return valve.
1.
The body consists of a steel reservoir (water tank)
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 ".
2.
The flange is outfitted with: electric heater and
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.
3.
The safety-return valve prevents the appliance's
complete 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.
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! Improper installation and connection of
the appliance may make it hazardous for the health
and life of consumers. It may cause grievous and
permanent consequences, including but not limited to
physical injuries and/or death. Improper installation and
connection of the appliance may also lead to damage to the
consumers' property /damage and/ or destruction/, or to
that of third persons, as a result of, but not limited to
flooding, explosion and/or fire.
Installation, connection to the main water and power supply,
and putting into operation must be carried out by certified
electricians and technical personnel certified in installation of
this category of appliances, who have obtained their license
in the state where the installation and commissioning of the
appliance are carried out, and in compliance with its local
legislation.

Instructions for use and maintenance
1.
Mounting
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.
The appliance is affixed to a wall via the mounting
brackets attached to the unit's body (if the brackets are
not attached to the unit's body, they must be affixed in
place via the provided bolts). 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 310 mm (fig. 1a).
For water heaters intended for horizontal mounting, the
distances between the hooks vary for the different models
and are specified in the table 1 to Fig. 1b.
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.

Water heater connection to the pipe network
Fig. 4: a) - for vertical; b) - for horizontal installation
Where: 1 - Inlet pipe; 2 - Safety valve; 3 - reducing valve (for
water main pressure > 0,6 MPa); 4 - Stop valve; 5 - Funnel
connected to the sewer network; 6 – Hose; 7 - Drain water tap
Upon connecting the water heater to the water mains you
must consider the indicative color markings /rings/ affixed
to the pipes: blue for cold / incoming/ water, red for hot /
outgoing/ water.
The mounting of the safety return-valve supplied with the
water heater is obligatory. The safety return-valve must be
mounted on the cold water supply pipe, in observance of
the direction arrow stamped on its body, indicating the
incoming water's direction. Additional stopcocks must
not be mounted between the safety return-valve and the
water heater.
Exception: If the local regulations (norms) require the
usage of another protection valve or mechanism (in
accordance with EN 1487 or EN 1489), then it must
be bought additionally. For mechanisms operating in
accordance with EN 1487 the announced operational
pressure must be no more than 0.7 MPa. For other
protection valves, the pressure at which they are
calibrated must be 0.1 MPa lower than the one marked on
the appliance's sign. In these cases the safety valve which
the appliance is supplied with should not be used.
