8.3 Procedure

NOTE
Only software that is authorised and approved by the
manufacturer can be installed on the machine's control
system.
The heat pump is commissioned via the heat pump manager
(controller -N1). Settings should be made in compliance with
the heat pump manager's instructions.
At heating water temperatures under 7°C, commissioning is not
possible. The water in the buffer tank must be heated with the
2nd heat generator to at least 22°C.
To ensure problem-free commissioning, the following proce-
dure is to be implemented:
1) Close all consumer circuits.
2) Ensure that the heat pump has the correct water flow.
3) Use the manager to select the automatic operating mode.
4) In the special functions menu, start the "Commissioning"
program.
5) Wait until a return temperature of at least 29°C has been
reached.
6) Now slowly reopen the heating circuit valves in succession
so that the heating water flow rate is constantly raised by
slightly opening the respective heating circuit. The heat-
ing water temperature in the buffer tank must not be al-
lowed to drop below 24°C during this process. This en-
sures that the heat pump can be defrosted at any time.
7) When all heating circuits are fully open and a return tem-
perature of at least 22°C is maintained, the commissioning
is complete.
CAUTION!
Operating the heat pump at low system temperatures may
cause the heat pump to break down completely.
CAUTION!
Due to the solubility of propane in water, propane may enter
the hydraulic circuit in the event of leakage at the plate heat
exchanger despite the safety valve and the bubble separator.
CAUTION!
Commissioning, maintenance and repair only by personnel
who have verifiably been trained in dealing with the
refrigerant propane.

Maintenance work

9.1 General

NOTE
The maintenance instructions must be observed.
Work on the heat pump must only be performed by authorised
and qualified after-sales service technicians!
The device contains combustible refrigerant. Avoid ignition
sources in the safety zone!
Before starting the maintenance, the system log book must be
observed with respect to repairs and modifications already car-
ried out.
Periodic inspections required by law, e.g. German industrial
safety regulations (BetrSichV), etc., must also be observed.
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 commercially availa-
ble domestic cleaner.
NOTE
Never use cleaning agents containing sand, soda, acid or
chloride, as these can damage the surfaces.
NOTE
Only software that is authorised and approved by the
manufacturer can be installed on the machine's control
system.
NOTE
Only original spare parts may be used
CAUTION!
Maintenance and operating instructions for the machine and
the switch box must be taken into account
CAUTION!
The leakage tightness of the refrigerant circuit must be tested
after all assembly work is complete and the external power
supply (load and control voltage) has been connected.
