IT IS AT THE RISK OF DEATH AND THEREFORE IT IS FORBIDDEN TO PUT THE
WATER TANK AND THE HEAT EXCHANGERS UNDER A PRESSURE LARGER
THAN THE PERMITTED OPERATION PRESSURE (0.7 MPa) !
During connection to the water pipeline system, it is compulsory to keep the
building order of the fittings according Figure 7.3. -1., as proper operation of the
appliance highly depends on that.
HV - Cold water
MV - Hot water
AN - Magnesium Anode
E - Electric heating
HB - Heating agent inlet from heat
exchanger or external heat
exchanger (in case of type HB200C)
HK - Heating agent outlet from heat
exchanger or external heat
exchanger (in case of type HB200C)
KK - Condensation outlet
The combined safety valve must be connected to the cold water branch
considering the flow direction indicated by the arrow. The maximum distance between
the appliance and the valve is 2 m, and two bends (arc, knee) are permitted. . The
appliance has to be equipped with safety valve controlled for an operation pressure of
max. 7 bar. The safety valve has to be mounted directly before the tank onto the cold
water pipe branch, in a frost-free environment. The drainage pipe has to be connected
to the safety valve in a way that it is always directed downwards and located in a frost-
free environment. The feeding pressure of incoming cold water must not exceed 5.25
bar pressure in case of valve with operation pressure of 7 bar. In case of valve with
lower pressure values, maximal feeding pressure has to be defined concerning mini-
Figure 7.3.-1.
