CONNECTION TO THE WATER SUPPLY
The water heater is constructed for cross-flow (non-pressure) system of installation. This
system enables supply of water only at one outlet point. The connection must be performed
correspondingly to the diagram of the water supply.
For cross-flow system of installation an adequate mixing tap must be purchased. For the
execution above sink is needed a mixing tap above sink, and for execution under the sink
the mixing tap under the sink. Inlet of cold water is marked with blue colour and the outlet
of hot water is marked with red colour. Upon the inlet pipe before the mixing tap it is
mandatory to built-in a non-return valve preventing the running of water of the tank if the
water in the network runs short. If the pressure in water supply network surpasses 5 bar,
before the mixing tap also a reduction valve must be built in.
By choice of the cross-flow mixing tap, particular attention must be paid to the data of sup-
plier about reduction of pressure by the resistance appearing by flow of water through the
mixing tap. By entirely open outlet valve this must not surpass 0,2 bar. To the outlet pipe
of mixing tap no device driven by water or spray nozzle may be connected, which could
cause the increase of pressure in the tank of the water heater. If these instructions shall
not be respected during the operation, a damage of the heater may occur.
