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, 1b,
1c). For water heaters intended for horizontal mounting, the distances
6
Instructions for use and maintenance
between the hooks vary for the different models and are specified
in the tabl. 6 and 7 to Fig. 1d, 1e. For water heaters intended for floor
installation - tabl.6,7 2 to Fig. 1h, 1g.
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. 3:
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 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 (fig3)
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 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.
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.
