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 thermostat.
2.
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.
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.
V. MOUNTING AND SWITCHING ON
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.
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. 1c. For water heaters intended for floor installation - 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.

Where: 1 - Inlet pipe; 2 - Safety valve; 3 - reducing valve (for water main
English
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 boilers 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 4a and 4 b) 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.
