times when the heat pump should switch to a quieter oper-
ating mode.
14. Appliance shutdown
!
Material losses
Never interrupt the heat pump power supply, even out-
side of the heating season. Otherwise, system frost pro-
tection is not guaranteed.
The heat pump manager automatically switches the heat
pump to summer or winter mode.
14.1 Standby mode
To shut the system down, simply set the heat pump manager to
"Standby mode". This way, the safety functions that protect the
system remain enabled, e.g. frost protection.
14.2 Power interruption
If the system is to be isolated from the power supply permanently,
please observe the following:
!
Material losses
If the heat pump is completely switched off and there is a
risk of frost, drain the system on the water side.
15. Maintenance
WARNING Electrocution
 Prior to commencing any service or cleaning work,
isolate the appliance across all poles from the
power supply.
Following disconnection from the power supply, parts of
the appliance may remain energised for 2minutes until
the inverter capacitors have discharged.
We recommend a regular inspection (to establish the current con-
dition of the system), and maintenance if required (to return the
system to its original condition).
Check the condensate drain (visual inspection). Remove any con-
taminants and blockages immediately.

16. Troubleshooting
WARNING Electrocution
 Before working on the appliance, isolate it from the
power supply at the control panel.
Following disconnection from the power supply, parts of
the appliance may remain energised for 2minutes until
the inverter capacitors have discharged.
Note
Please observe the instructions for the heat pump man-
ager.
If the fault cannot be located during a service using the heat pump
manager, open the control panel in emergencies and check the
IWS settings.
