Cleaning / maintenance

8.1 Maintenance
To protect the paintwork, avoid leaning anything against the
device or putting objects on the device. External heat pump
parts can be wiped with a damp cloth and domestic cleaner.
NOTE
Never use cleaning agents containing sand, soda, acid or
chloride as these can damage the surfaces.
To prevent faults due to sediment in the heat exchanger of the
heat pump, ensure that the heat exchanger in the heating sys-
tem cannot be contaminated. In the event that operating mal-
functions due to contamination still occur, the system should
be cleaned as described below.

8.2 Cleaning the heating system

ATTENTION!
The integrated dirt trap must be cleaned at regular intervals.
The maintenance intervals should be defined according to the
degree of soiling in the system. The filter insert should also be
cleaned.
For cleaning, the heating circuit must be made pressureless in
the vicinity of the dirt trap, the filter compartment unscrewed,
and the filter insert removed and cleaned. Assembly carried out
in reverse order requires attention to correct assembly of the
screen inserts and tightness of the screw joints.
The ingress of oxygen into the heating water circuit may result
in the formation of oxidation products (rust), particularly if steel
components are used. They enter the heating system via the
valves, the circulating pumps and/or plastic pipes. It is there-
fore essential - in particular with respect to the entire pipework
- that only diffusion-resistant materials are used.
NOTE
We recommend the installation of a suitable corrosion
protection system to prevent the formation of deposits (e.g.
rust) in the condenser of the heat pump. We recommend
equipping
diffusion-open
electrophysical
anti-corrosion
system).
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.
In case of doubt, consult the manufacturer of the cleaning
agents!

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. Do this by opening the heat pump as described
in Chapter 6.1.
ATTENTION!
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 areas in individual cases. 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.

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. In this case, con-
sult the "Faults and troubleshooting" page in the operating in-
structions of the heat pump manager. If you cannot correct the
fault yourself, please contact your after-sales service techni-
cian.
ATTENTION!
Any work on the heat pump may only be performed by
an
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.
