9.3 Cleaning the Heat Source
System
A dirt trap is inserted in the heat source inlet of the heat pump to
protect the evaporator against the ingress of impurities. When
the system is first put into operation, the filter screen of the dirt
trap should be cleaned in relatively short intervals. These inter-
vals can be prolonged once the amount of impurities decreases.

9.4 Water Quality Requirements

The ground water should not contain any substances that could
form deposits. The limit values for iron (< 0.2 mg/l) and manga-
nese (< 0.1 mg/l) must be adhered to prevent iron ochre sedi-
mentation in the heat pump system.
The use of surface water or water containing salt is not permissi-
ble. Your local water utility can provide you with general informa-
tion regarding the possible use of ground water. Water analyses
are carried out by specially-equipped laboratories.
It is not necessary to carry out a water analysis with regard to
evaporator corrosion if the annual mean temperature of the
ground water does not exceed
13 °C). In this case, the limit values for iron and manganese must
be adhered to (iron ochre sedimentation).

10 Faults / Trouble-
Shooting
This heat pump is a quality product and is designed for trouble-
free operation. In the event that a fault should occur, it will be
shown on the heat pump manager display. Simply consult the
Faults and Trouble-Shooting page in the operating instructions of
the heat pump manager.
If you cannot correct the fault yourself, please contact your after-

qualified after-sales service technicians.
ATTENTION!
Disconnect all electrical circuits from the power source prior to opening
the device.
11 Decommissioning /
Disposal
Before removing the heat pump, disconnect it from the power
source and close all valves. The heat pump must be installed by
trained personnel. Observe all environmentally-relevant require-
ments regarding the recovery, recycling and disposal of materi-
als and components in accordance with all applicable standards.
Particular attention should be paid to the proper disposal of re-
frigerants and refrigeration oils.
