CONNECTION TO THE WATER SUPPLY
Inlet and outlet of water are on the water heater pipes marked with colour. The
supply of cold water is marked with blue, the outlet of warm water is marked with red.
The water heater can be connected to the water supply in two manners. Closed
pressure system of connection enables the outlet of water on several outlet spots,
non-pressure system enables only one outlet point. With regard to the system of
connection chosen, also the suitable mixing taps must be purchased.
By open non-pressure system it must before the water heater a non-return valve be
built-in preventing the running of water of the tank if in the network the water runs short.
By this system of connection, the cross-flow mixing tap must be used. In the water
heater, due to the heating the volume of water is increasing, which causes the dropping
of water of the mixing tap pipe. By strong squeezing of knob of the mixing tap the
dropping of water can not be prevented, but the mixing tap can only be damaged. By
closed pressure system of connection on the outlet spots the pressure mixing tap must
be used. For safety reasons the supply pipe must be fitted with a return safety valve or
alternatively, a valve of the safety class that prevents the pressure in the tank from exceed-
ing the nominal pressure by more than 0.1 MPa.
By heating of water in the water heater the pressure of water in the tank is increasing to
the limit which is adjusted in the safety valve. Because the return of water back to the
water supply is prevented, dropping of water from outlet opening of the safety valve can
occur. The dropping water may be let to the outlet over an intercepting accessory which
is placed under the safety valve. In order to do this you should first unscrew the protec-
tive cover off the water heater.
