III. DESCRIPTION AND PRINCIPLE OF WORK
The appliance is designed to operate in regions where the water hardness is not more than
10°dH. In case that it is installed in a region where the water is harder it is possible that
limestone precipitation accumulate very fast. This can cause a specific noise during heating,
as well as fast damaging of the electrical part. For regions with harder water yearly cleaning
of the limestone precipitation in the appliance is recommended, as well as usage of not more
than 2 kW of heating power.
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 '' .
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.
IV. 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.
Notice: The installation of the unit is at the buyer's expense.
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 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.

2. Water heater connection to the pipe network.
Fig. 4:
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.
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 ppliances 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.
After it has been assembled it should be in position as shown on Fig. 2.
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.4) 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 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 II, 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.
3. Water heater connection to the electrical network
Make sure the appliance is full of water prior to switching on the
electrical mains power.
3.1. Models with power cord with a plug are connected by inserting the 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) conductor shall be used
for the connection – cable 3 x 2.5 mm² (cable 3 x 2.5 mm² for power > 3700W).
The electrical circuit supplying the appliance must have an in-built device ensuring
the splitting of all terminal poles under conditions of super-voltage of category III.
