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.
In order to provide correct operation of the relief valve, periodical inspections of the relief
valve must be carried out by the user. 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 return safety valve no closing valve may be built-in
because with it the function of return safety valve would be impeded.
The water heater may be connected to the water network in the house without reduction
valve if the pressure in the network is lower than 0.5 MPa (5 bar). If the pressure exceeds
0.5 MPa (5 bar), a reduction valve must be installed. Prior to the electric connection the
water heater must obligatorily 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.
CONNECTION OF THE WATER HEATER TO THE ELECTRIC NETWORK
Before connecting to power supply network, install a power supply cord in the water heater,
with a min. diameter of 1,5 mm
2
(H05VV-F 3G 1,5 mm
2
). For it the protection plate must be
removed from the water heater.
The connection of water heater to the electric network must be performed according to
standards for electric installation. Install a disconnect switch (separating all poles from the
power supply network) between the water heater and the permanent power connection, in
compliance with the national regulations.
