After being connected to the water pipeline system and the electric power
system, the hot water tank has to be filled up with water from the household water
supply system. The tank must be filled up with water before switching on the
heating. During filling the tank up with water, open the hot water valve of the closet
tap while keep all the other valves closed. Then open the closing valve mounted in
the cold water pipe (Figure 7.3-1., item No. 1. ). The tank is filled up when water
appears on the tap. For flushing purposes, the water must be flown for some
minutes, then you can close the valve of the hot water.
PLEASE TURN TO A TECHNICIAN TO CHECK THE FIRST HEATING.
Perform an eye check to decide whether connections of edges and pipe
fittings are leaking or not – and tighten them carefully, if necessary. The appliance
can be connected to the electric power system only after this check. In order to
switch the heat pump of the water heater in a mode, press the ON/OFF key located
on the control panel. Before setting the clock and other parameters or programs,
please follow the instructions of chapter 4.
