NOTICE
In Europe, the greenhouse gas emissions of the total
refrigerant charge in the system (expressed as tonnes
CO -equivalent) is used to determine the maintenance
2
intervals. Follow the applicable legislation.
Formula to calculate the greenhouse gas emissions:
GWP value of the refrigerant × Total refrigerant charge [in
kg] / 1000
Please contact your installer for more information.
WARNING
The refrigerant in the system is safe and normally does not
leak. If the refrigerant leaks in the room, contact with a fire
of a burner, a heater or a cooker may result in a harmful
gas.
Turn off any combustible heating devices, ventilate the
room and contact the dealer where you purchased the unit.
Do not use the system until a service person confirms that
the portion where the refrigerant leaks is repaired.
19.4 After-sales service and warranty
19.4.1 Warranty period
▪ This product includes a warranty card that was filled in by the
dealer at the time of installation. The completed card has to be
checked by the customer and stored carefully.
▪ If repairs to the product are necessary within the warranty period,
contact your dealer and keep the warranty card at hand.
19.4.2 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 electric 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 non-combustible, 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.

The table assumes the following conditions of use:
▪ Normal use without frequent starting and stopping of the unit.
Depending on the model, we recommend not starting and
stopping the machine more than 6 times/hour.
▪ Operation of the unit is assumed to be 10 hours/day and
2,500 hours/year.
NOTICE
▪ The table indicates main components. Refer to your
maintenance and inspection contract for more details.
▪ The table indicates
maintenance cycles. However, in order to keep the unit
operational as long as possible, maintenance work may
be required sooner. Recommended intervals can be
used for appropriate maintenance design in terms of
budgeting maintenance
Depending on the content of the maintenance and
inspection contract, inspection and maintenance cycles
may in reality be shorter than listed.
19.4.4 Shortened maintenance and replacement
cycles
Shortening of "maintenance cycle" and "replacement cycle" needs to
be considered in following situations:
The unit is used in locations where:
▪ Heat and humidity fluctuate out of the ordinary.
▪ Power fluctuation is high (voltage, frequency, wave distortion, etc.)
(the unit cannot be used if power fluctuation is outside the
allowable range).
▪ Bumps and vibrations are frequent.
▪ Dust, salt, harmful gas or oil mist such as sulphurous acid and
hydrogen sulfide may be present in the air.
▪ The machine is started and stopped frequently or operation time is
long (sites with 24 hour air-conditioning).
