CONNECTION TO THE WATER SUPPLY SYSTEM
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 safety 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 exceeding 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 protective cover off the water heater. In
case the existing plumbing does not enable you to pipe the dripping water from the return safety
valve into the drain, you can avoid the dripping by installing a 3-litre expansion tank on the inlet
water pipe of the boiler.
You should ensure that the return safety valve is functioning properly by checking it on a regular
basis i.e. every 14 days. To check the valve, you should open the outlet of the return safety
valve by turning the handle or unscrewing the nut of the valve (depending on the type of the
valve). The valve is operating properly if the water comes out of the nozzle when the outlet is
open.
Between the water heater and safety valve no closing valve may be built-in because it
would disable the operation of non-return safety valve.
The water heater may be connected to the water supply in the house without reduction valve if
the pressure in the network is lower than 0.5 MPa. If the pressure in the network surpasses 1.0
MPa, two reduction valves must be built-in, one after another.
Prior to the electric connection, the water heater must mandatorily be filled with water. By first
filling the tap for the hot water upon the mixing tap must be opened. When the heater is filled
with water, the water starts to run through the outlet pipe of the mixing tap.
