Cleaning / maintenance

9.1 Maintenance
To prevent faults due to sediment in the heat exchangers, care
must be taken to ensure that no impurities can enter either the
heat source system or the heating system. In the event that op-
erating malfunctions due to contamination occur nevertheless,
the system should be cleaned as described below.

9.2 Cleaning the heating system

The ingress of oxygen into the heating water circuit may result
in the formation of oxidation products (rust), particularly if steel
components are used. These 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 piping of under-
floor heating systems - that only diffusion-proof 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
(e.g. ELYSATOR system).
Residue from lubricants and sealants may also contaminate the
heating water.
In the event 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 both cases, 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 liquifier. It is then important
that the system be thoroughly flushed using appropriate neu-
tralising agents to prevent any damage from being caused by
cleaning agent residue remaining in the system.
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.

9.3 Cleaning the heat source
system
ATTENTION!
The supplied dirt trap must be inserted in the heat source inlet
of the heat pump to protect the evaporator against the ingress
of impurities.
The filter sieve of the dirt trap should be cleaned one day after
start-up. Further checks must be set according to the level of
dirt. If no more signs of contamination are evident, the filter can
be removed to reduce pressure drops.

10 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 technician.
an
ATTENTION!
Work on the heat pump must only be performed by
authorised and 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 environmental requirements re-
garding the recovery, recycling and disposal of materials and
components in accordance with all applicable standards. Par-
ticular attention should be paid to the proper disposal of refrig-
erants and refrigerant oils.
