NEVER inspect or service the unit by yourself. Ask a
qualified service person to perform this work.
NOTICE

gases into the atmosphere.
Refrigerant type: R32
Global warming potential (GWP) value: 675
Periodical inspections for refrigerant leaks may be required

equivalent
tonnes: GWP value of the refrigerant × total refrigerant
charge [in kg]/1000
Contact your installer for more information.
WARNING
Safety shut-off valves shall not be reset until the room has
been ventilated. Resetting may result in additional
flammable refrigerant to be released into the room.
7.3 After-sales service
7.3.1 Recommended maintenance and
inspection
Since dust collects when using the unit for several years,
performance of the unit will deteriorate to some extent. As taking
apart and cleaning interiors of units requires technical expertise and
in order to ensure the best possible maintenance of your units, we
recommend to enter into a maintenance and inspection contract on
top of normal maintenance activities. Our network of dealers has
access to a permanent stock of essential components in order to
keep your unit in operation as long as possible. Contact your dealer
for more information.
When asking your dealer for an intervention, always state:
▪ The complete model name of the unit.
▪ The manufacturing number (stated on the nameplate of the unit).
▪ The installation date.
▪ The symptoms or malfunction, and details of the defect.
WARNING
▪ Do NOT modify, disassemble, remove, reinstall or
repair the unit yourself as incorrect dismantling or
installation may cause an electrical shock or fire.
Contact your dealer.
▪ In case of accidental refrigerant leaks, make sure there
are no naked flames. The refrigerant itself is entirely
safe, non-toxic and mildly flammable, but it will
generate toxic gas when it accidentally leaks into a
room where combustible air from fan heaters, gas
cookers, etc. is present. Always have qualified service
personnel confirm that the point of leakage has been
repaired or corrected before resuming operation.
