mini-maxi tolerance limits of the safety valve. If it exceeds this value, pressure reduction
device should be connected in front of the safety valve.
The safety valve is not an accessory of the appliance.
IT IS FORBIDDEN TO BUILD WATER PIPELINE FITTING BETWEEN THE
VALVE AND THE APPLIANCE.
Before mounting the valve, the cold water pipeline must be flushed thoroughly, in order to
avoid any damage caused by any possible pollution. The combined safety valve contains a
one-way valve. Therefore, it is not needed to mount a separate one-way valve. During the
heating, the expanding water has to leak through the drainage pipe branch of the combined
safety valve. During installation of the valve, one should pay attention to ensure that this
leaking remains visible.
IT IS FORBIDDEN TO CLOSE THE DRAINAGE PIPE BRANCH OR TO
DIVERT WATER LEAKING IN A NON-VISIBLE WAY.
If the pipeline system pressure exceeds the value of 0.6 MPa – only in a temporary way -, a
pressure reduction valve has to be mounted in front of the hot water tank, at the location of
item No. 3 as described in Figure 3. In case of lacking pressure reduction valve, the safety
valve will leak besides heating under this pressure. It is the task of the user to purchase and
mount the pressure reduction valve. If the combined safety valve is connected to the hot
water tank without the reducing device, in order to discharge the hot water tank, a
discharge faucet or valve should be mounted to the cold water pipe of the appliance,
adding a standard T-shaped fitting. It is the task of the user to purchase the valve (faucet).
An arbitrary number of taps and mixing faucets can be mounted on the hot water tank. It is
rational to block the flow back of the hot water through the outlet towards the cold water
pipeline system by mounting a one-way valve in the cold water pipe in front of the taps. A
closing valve needs to be mounted in the cold water pipeline leading to the tank in front of
the fittings (combined safety valve, one-way valve, etc.) With the help of this closing
valve, both the hot water tank and the water pipeline fittings can be disconnected from the
water pipelines system (in case of failure or other maintenance work).
EARTHING WIRE CONNECTION
To perform electric connection, take out the screws of the cover of the fitting house and
remove the cover. The stripped wire end of the green and yellow wire has to be placed
under the earthing washer on the earthing screw and it has to be mounted with screw nut.
EARTHING HAS TO BE PERFORMED FOR APPLIANCE LAYOUTS THAT DO
NOT CONTAIN ELECTRIC HEATING, AS WELL.
The protective earthing has to comply with the instructions of the Hungarian Standard
MSZ 2364.
PUTTING INTO OPERATION
After connection into the water pipeline system, the hot water tank can be put into
operation. Please turn to a professional technician to control correct operation at the first
operation.
The tank must be filled up with water before switching on the heating. During filling
the tank up with water, open the hot water valve of the closest tap while keeping all the
other valves closed. Then open the closing valve mounted in the cold water pipe (Figure 3,
item No. 1). The tank is filled up when water appears on the tap. For flushing purposes, the
water must be flown for some minutes, then you can close the valve of the hot water.
TURN TO A PROFESSIONAL TECHNICIAN TO CHECK THE FIRST HEATING.
