13. Appliance maintenance
WARNING: Electrocution
For maintenance work, cut off the power supply to
the indoor unit of your heat pump.
i Information
Ensure that the refrigerant circuit of your heat pump
is tested for leaks once a year (in acc. with Regu-
lation (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 neces-
sary a service on the heat pump to be carried out 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. Heat pumps
are refrigeration equipment and are subject to the pro-
visions 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. You can find more
information at www.ochsner.com.
We recommend testing the heating water system pressure
and correcting it if necessary (pressure too high/low).
We recommend adjusting the charge pressure in the dia-
phragm 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.
13.1 Testing safety valves
i Information
The indoor unit has internal safety valves for the
heat sink system (DHW, heating) and the heat
source system (brine circuit).
»
Observe the national and regional regulations
regarding the prescribed regular operational
tests.
»
Remove the left-hand appliance casing panel to gain
access to the internal safety valves. (see page 20,
Disassembling the appliance casing)
»
To test, turn the red knob on the safety valve until wa-
ter emerges from the safety valve drain.
»
Ensure that the safety valve is closed again after the
test.
