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.
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.
English
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.
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.
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.
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)
