In order to drain condensate water continuously, please install the appliance on a
horizontal floor. If this is not possible, please ensure that the drain vent is at the lowest
possible place. It is recommended to place the appliance in a way that the inclination
angle between the appliance and a vertical line is not more than 2°.
9.5. First start up
Before first start up of the appliance, please, check the following
elements:
⋅
Adequate installation of the appliance;
⋅
Adequate connection of water pipes and electric wires;
⋅
The leaking of cooling pipe has been tested;
⋅
Efficient water discharge pipe.
⋅
Full insulation protection;
⋅
Adequate earthing;
⋅
Adequate power source;
⋅
No obstacle to air inlet and air outlet;
⋅
There is no air in the water pipeline and all the valves are in open
position;
⋅
Efficient electric leak protection is operating;
⋅
Water inlet pressure is sufficient(≥0,15MPa)
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
Figure 7.2.-9. Figure 7.2.-10.
