DESCRIPTION AND PRINCIPLE OF WORK
IV.
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
(serpentine tube). The heat exchenger's entrance and exit are located at the
sides and represent pipes with thread G ¾ ''.
The flange is outfitted with: electric heater and thermostat. The water
2.
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 emptying
3.
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
V.
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.
Notice: The installation of the unit is at the buyer's expense.
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.
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 2 to Fig. 1c. For water heaters intended
for floor installation - table 2 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.

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.

Instructions for use and maintenance
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.
The presence of other /old/ safety return-valves may lead to a
breakdown of your appliance and they must be removed.
Other type of stopping armature is not allowed between the protection
return valve (the protective device) and the appliance.
The attaching of the safety return-valve to threads longer than 10 mm is not
allowed, otherwise this may damage the valve and poses danger for your
appliance.
With appliances for vertical assembly, the safety valve has to be
connected to the ingoing pipe with the safety plastic panel of the
appliance being taken off.
The safety valve and the pipe between the valve and the water heater
must be protected from freezing. During hose draining - its free end must
be always open to the atmosphere (not to be immersed). Make sure that the hose
is also protected from freezing.
Opening the cold-water stopcock of the water supply piping network and
opening the hot-water stopcock of the water-mixing faucet carries out the
filling of the water heater with water. After the filling is complete, a constant
stream of water must begin to flow from the water-mixing faucet. Now you
can close the hot water stopcock.
In the event you must empty the water heater, first you must cut off its power
supply. The inflow of water from the water mains must first be terminated and
the hot water tap of the mixing-faucet must be opened. The water tap 7 (fig
3a and 3b) must be opened to drain the water from water tank. If there is no
such tap build in the pipe line, than the water can be drain as follow:
•
Models equipped with safety valve with lever - You can drain the water
from the water heater by lifting the safety return-valve's lever. Water will drain
from the safety return-valve's drainage opening
•
Models equipped with safety valve without lever - water can be drain
directly from inlet pipe of water tank after when you disconnect it from water
main
In the event of removing the flange, the discharge of several liters of water,
which remain in the water tank, is normal.
Measures must be undertaken to prevent damage from discharging
water during draining
In case that the pressure in the water mains is over the value pointed out
in the above paragraph I, then it is necessary to assemble a pressure
reduce valve, otherwise the water heater would not function properly.
The Manufacturer does not assume any liability for problems arising out
of the appliance's improper use.
Water heater connection to the electrical network
3.
Make sure the appliance is full of water prior to switching on the
electrical mains power.
Models with power cord with a plug are connected by inserting the
3.1.
plug into a contact. They are switched off the power supply by drawing
the plug out of the contact.
The wall-plug must be properly connected to a separate electrical
circle that is provided with a protector. It must be earthed.
3.2.
The appliance has to be connected to a separate electricity circuit of
the stationary electrical wiring. The connecting has to be constant- with
no plug contacts. The circuit has to be supplied with a safety fuse (16A)
and with inbuilt device to ensure disconnection of all pole pieces in the
conditions of over-voltage from category III.
The connecting of the conductors of the supply cord of the appliance has
to be carried out as follows:
•
conductor with brown insulation – to the phase conductor of the electrical
wiring (L)
•
conductor with blue insulation- to the neutral conductor of the wiring (N)
•
conductor with yellow-green insulation – to the safety conductor of the
wiring (
)
3.3.
Models without power cord
The appliance has to be connected to a separate electricity circuit of the
stationary electrical wiring. The circuit has to be supplied with a safety fuse
16A (20A for power > 3700W). Copper single core (rigid – non stranded)
