Faults / troubleshooting

This heat pump is a quality product and is designed for trouble-
free operation. Should a fault occur, however, it will be indicated
on the heat pump manager display. In this case, consult the
"Faults and troubleshooting" page in the operating instructions of
the heat pump manager. If you cannot correct the fault yourself,
please contact your after-sales service technician.
ATTENTION!
Work on the heat pump must only be performed by authorised and
qualified after-sales service technicians!
NOTE
The repair instructions must be observed.
The following steps must be adhered to before starting the work:
1) Before starting the work, ensure that the power supply to the
device is disconnected externally.
2) It is prohibited to remain in the direct vicinity of the device
during storms (risk of lightning)!
3) Work outdoors on electrical equipment or live components
may only be carried out in dry weather conditions. In wet
conditions (rain, snow etc.), the device must be closed cor-
rectly.
4) The refrigeration circuit must not be damaged.
5) The device contains combustible refrigerant. Avoid ignition
sources in the danger area!
6) Before opening the device, check the work environment with
a suitable gas detector. Position the gas detector switched
on in the device during all subsequent work.
Carry out a leakage tightness test before switching on the exter-
nal power supply.
A mobile switch-off device must be mounted before connecting
the external power supply (see attachment Chap. 3.2 on P. A-
VII). If there is a risk of refrigerant escaping during repair work, a
mobile ventilation (ex-proof fan) can be used as a supporting or
even essential measure.
All repair work must only be carried out by a technician who is
trained in handling flammable refrigerants, has the necessary ex-
perience and fulfils the legal requirements in the relevant country
where the refrigerating system is operated.
Before starting the repair work on the relevant component, the
paint protector must be checked to ensure it is in the original
state. Paint protectors that have to be removed for the repair
work must be mounted again once the work is complete.
Before starting the repair, the system log book must be observed
with respect to repairs and modifications already carried out.

10 Decommissioning /
disposal
Before removing the heat pump, disconnect the machine exter-
nally from the power source and shut it off hydraulically. The heat
pump must be dismantled by trained personnel. Environmen-
tally-relevant requirements with regard to recovery, reuse and
disposal of materials and components in accordance with the
valid standards must be complied with. Particular attention
should be paid to the proper disposal of the flammable refrigerant
and refrigerant oil. Anyone carrying out work on the refrigeration
circuit must be certified to safely handle inflammable refrigerants
or be supervised by a person having such certification.
ATTENTION!
Work on the heat pump must only be performed by authorised and
qualified after-sales service technicians!
ATTENTION!
It is prohibited to remain in the direct vicinity of the device during storms
(risk of lightning)!
ATTENTION!
Work outdoors on electrical equipment or live components may only be
carried out in dry weather conditions. In wet conditions (rain, snow etc.),
the device must be closed correctly.
