PUTTING INTO OPERATION

Before connecting the water heater to the power supply system, it should be completely filled up
with water, with one hot water faucet kept open. This faucet should be closed when water outflow is
performed without noises in the pipes, in a regular way. Then the whole hot water pipeline should
be flushed gradually, through opening adequate faucets.
CONNECTION TO THE PIPELINE SYSTEM
Galvanized steel pipe can be used as hot water and cold water pipes.
IT IS AT THE RISK OF DEATH AND THEREFORE IT IS FORBIDDEN TO PUT THE
WATER TANK AND THE TEMPERATURE EXCHANGER UNDER A PRESSURE
LARGER THAN THE PERMITTED OPERATION PRESSURE (6 BAR)!
During connecting the appliance to the pipeline system, it is of utmost importance to keep the
mounting order of the fittings according to figure 1 (for types IDE...F and IND...F) and figure 2
(for types IDE...S and IND...S) as this is indispensable for the correct operation of the appliance.
A safety valve has to be built in the connecting cold water branch (which is a safety valve and a
one-way valve). The maximum opening pressure of the safety valve is 7 bar.
The safety valve is not part of the shipping package.
Adequate pipeline and waste water collection systems should be ensured on the location of the
installation of the appliance. Water leaking through the safety valve has to be channeled. There is no
need to channel leaking water if a sanitary expansion tank of adequate size is built in the system.
IT IS FORBIDDEN TO CLOSE THE WATER OUTLET TUBE OR TO DIVERT WATER
LEAKAGE IN A NON-VISIBLE WAY!
If the water pressure in the system exceeds the value of 0.6 MPa temporarily, a pressure reducing
valve has to be mounted in front of the hot water tank. This pressure reducing valve has to be
purchased and mounted by the customer. The pressure reducing valve has to be mounted in front of
the combined safety valve. An arbitrary number of taps and mixing faucets can be mounted on the
hot water tank.
The flow back of the hot water through the outlet towards the pipeline system is blocked by the one-
way valve (which is not an accessory of the hot water tank). Using the closing valve, the hot water
tank can be disconnected from the pipeline system.
MOUNTING WITH CIRCULATION PUMP
This mounting mode is proposed by the manufacturer. The circulation pump ensures significant
water yield levels in the heat exchanger, therefore it produces definitely good heat exchange
performance. The appliance is controlled by a thermostat, which is mounted on the water heater,
ensuring controlling of the temperature of household hot water. The connection of the appliance to
the central heating unit has to be performed only according to figure 1-2, exclusively. The heat
exchanger connection has 1" external thread. It is recommended to use steel pipes, in order to avoid
risk of corrosion. Before filling up the system, it has to be flushed thoroughly with the help of water
circulation, so that pollution of the water is removed, to reduce the risk of damage to the combined
safety valve.
CONNECTION TO THE ELECTRIC SYSTEM
The hot water tank is equipped with a thermostat of 6 contacts so it can not be simply connected and
operated only from a supply system of AC current. The connection to the electric system is
performed according to figures 3., 4. and 5. IT IS FORBIDDEN TO APPLY ANY WALL
SOCKET. According to conventional way, the diagram contains the elements used in international
technical representation. It is indispensable to provide earthing of the metal parts of the water heater
