9 Maintenance
9.1 Service
For maintenance work, disconnect the
power supply to the indoor unit and
the outdoor unit of your heat pump.
NOTE
Ensure that the refrigerant circuit of
your heat pump is tested for leaks once
a year (in acc. with Regulation (EU) no.
517/2014).
- Ensure year-round access to
soldered joints in the refrigerant
circuit.
-
Document the results of the leakage
test in the system test report.
We recommend arranging for an inspection and if
necessary a service on the heat pump to be
conducted once a year. We draw your attention to
the fact that statutory regulations require regular
testing of heating systems by the system user.
The refrigerants used in OCHSNER heat pumps are
non-flammable, non-toxic and ozone neutral.
However, heat pumps are refrigeration equipment
and are subject to the provisions of the F-gas
Regulations (Regulation (EU) no. 517/2014).
OCHSNER Customer Service will be pleased to help
in carrying out maintenance and testing, in
particular as required by the F-gas Regulations.

more information, see

We recommend testing the heating water system
pressure and correcting it if necessary (pressure
too high/low).
We recommend adjusting the pre-charge pressure
in the diaphragm expansion vessel (DEV) on the
system accordingly (system height).
We recommend monitoring the flow rate of the
heat sink system (WNA) and if necessary the heat
source system (WQA) using the flow meters
specified by OCHSNER.
We recommend that when non-routine work
takes place requiring refilling (e.g. system
alteration or pipe breakage), a current water
assessment be prepared and the heat sink system
be refilled on the basis of this.
9.2 Cleaning and care
Indoor unit
Clean the indoor unit with conventional
household cleaning agents (water, mild soapy
solution). Do not use corrosive cleaning agents!
Outdoor unit
As indoor unit. Do not use coarse tools to remove
dirt from between the evaporator fins in the
outdoor unit. Use compressed air (max. 8 bar)
against the normal airflow direction to clean the
evaporator fins.
In case of heavy contamination,
we recommend notifying customer service or
your system partner.
Ensure that no ice is formed, especially around
walking surfaces and entrances around the
outdoor unit.
