Care

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.
To prevent faults due to sediment in the heat exchanger of the
heat pump, ensure that the heat exchanger in the heating sys-
tem cannot be contaminated. Should operating malfunctions
due to contamination still occur, however, the system should
be cleaned as described below.

10 Maintenance work

10.1 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.
EN-16
CAUTION!
The long-term leakage tightness of the entire hydraulic circuit
must be ensured (for example through repeated inspection).
The device is a permanently technically sealed system. In rare
cases, however, leakages may occur on the plate heat ex-
changer due to freezing. The risk is increased in particular in the
event of tampering on the dirt traps, if the requirements for fill-
ing the hydraulic circuit are not complied with, or if the mini-
mum flows are not observed.
CAUTION!
Commissioning, maintenance and repair only by personnel
who have verifiably been trained in dealing with the
refrigerant propane.

10.4 Maintenance intervals

Maintenance cycle
The standard maintenance interval is 6 months. If operated for
less than 3,000 hours per year and in conjunction with a corre-
sponding remote monitoring system, the maintenance interval
may be extended to 12 months.
