9 Maintenance and Cleaning
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. This oxygen enters the heating system
via the valves, the circulating pumps and/or plastic pipes. It is
therefore essential - in particular with respect to the piping of
underfloor heating systems - that only diffusion-proof materials
are used.
NOTE
º
ºººº
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 heating systems with an
electrophysical anti-corrosion system (e.g. ELYSATOR
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 liquifier in the heat pump, the system
must be cleaned by a heating technician.
According to today’s state of knowledge, we recommend using
a 5 % phosphoric acid solution for cleaning purposes. However,
if cleaning needs to be performed more frequently, a 5 % for-
mic acid solution should be used.
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 flow of the liquifier. It is 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 great care and all relevant regulations
of the employers’ liability insurance associations must be ad-
hered to.
The manufacturer's instructions regarding cleaning agent must
be complied with at all times.
9.3 Cleaning the Heat Source
System
A dirt trap is inserted in the heat source inlet of the heat pump
to protect the evaporator against the ingress of impurities.
When the system is first put into operation, the filter screen of
the dirt trap should be cleaned in relatively short intervals.
These intervals can be prolonged once the amount of impuri-
ties decreases.
9.4 Water Quality Requirements
The ground water should not contain any substances that
could form deposits. The limit values for iron (< 0.2 mg/l) and
manganese (< 0.1 mg/l) must be adhered to prevent iron ochre
sedimentation in the heat pump system.
The use of surface water or water containing salt is not permis-
sible. Your local water utility can provide you with general infor-
mation regarding the possible use of ground water. Water anal-
yses are carried out by specially-equipped laboratories.
It is not necessary to carry out a water analysis with regard to
evaporator corrosion if the annual mean temperature of the
ground water does not exceed
13 °C). In this case, the limit values for iron and manganese
must be adhered to (iron ochre sedimentation).
10 Faults / Trouble-Shooting
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
shown on the heat pump manager display. Simply consult the
Faults and Trouble-Shooting page in the operating instructions
of the heat pump manager.
If you cannot correct the fault yourself, please contact your
after-sales 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.
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 environmentally-relevant re-
quirements regarding the recovery, recycling and disposal of
materials and components in accordance with all applicable
standards. Particular attention should be paid to the proper dis-
posal of refrigerants and refrigeration oils.
