Residue from lubricants and sealants may also contaminate the
heating water.
In the case of severe contamination leading to a reduction in
the performance of the liquefier in the heat pump, the system
must be cleaned by a heating technician.
Based on current knowledge, we recommend carrying out the
cleaning with a 5 % phosphor acid or, if more frequent cleaning
is required, with a 5 % formic acid.
In either case, the cleaning fluid should be at room tempera-
ture. We recommend flushing the heat exchanger in the direc-
tion opposite to the normal flow direction.
To prevent acidic cleaning agents from entering the heating
system circuit, we recommend connecting the flushing device
directly to the flow and return of the liquefier of the heat pump.
It is then important that the system be thoroughly flushed using
appropriate neutralising agents to prevent any damage from
being caused by cleaning agent residue remaining in the sys-
tem.
Acids must be used with care and the regulations of the em-
ployers' liability insurance associations must be adhered to.
The manufacturer's instructions regarding cleaning agent must
be complied with at all times.
8.3 Cleaning the air system
The evaporator, ventilator and condensate outflow should be
cleaned of contamination (leaves, twigs, etc.) before each new
heating period.
CAUTION!
Before opening the device, ensure that all circuits are
powered down.
To prevent the evaporator and the condensate tray from being
damaged, do not use hard or sharp objects when cleaning.
Under extreme weather conditions (e.g. snow drifts), ice may
form on the air intake and air outlet grids. If this happens, the ice
must be removed in the vicinity of the air intake and air outlet
grids to ensure that the minimum air flow is maintained.
To ensure proper drainage from the condensate tray, it must be
regularly inspected and cleaned, if necessary.
All panelling can be removed to allow accessing the inside of
the device.
The two sash fasteners must be opened for this purpose. The
cover must then be slightly tilted forward and lifted off toward
the top.

Faults / troubleshooting
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
indicated on the heat pump manager display. Simply consult
the Faults and Trouble-shooting page in the operating instruc-
tions of
the heat pump manager. If you cannot correct the fault your-
self, please contact your aftersales service technician.
CAUTION!
Before opening the device, ensure that all circuits are
disconnected from the power supply!
After disconnecting the power supply, always wait for at least 5
minutes to allow stored electric charges to dissipate.
CAUTION!
Any work on the heat pump may only be performed by
authorised and qualified after-sales service technicians.
10 Decommissioning / disposal
Before removing the heat pump, disconnect it from the power
source and close all valves. The deinstallation of the heat pump
must be performed by technical personnel. Observe all environ-
mentally-relevant requirements regarding the recovery, recy-
cling and disposal of materials and components in accordance
with all applicable standards. Particular attention should be
paid to the proper disposal of refrigerants and refrigerant oils.
