11. After-sales service and warranty
11.1. 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 air conditioner are necessary within the warranty
period, contact your dealer and keep the warranty card at hand.
11.2. After-sales service
11.2.1. Recommendations for 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 air conditioner 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 air conditioner.
The manufacturing number (stated on the nameplate of the unit).
The installation date.
The symptoms or malfunction, and details of the defect.
11.2.2. Recommended inspection and maintenance cycles
Be aware that the mentioned maintenance and replacement cycles
do not relate to the warranty period of the components.
Table 1: "Inspection Cycle" and "Maintenance Cycle" list
Table 1 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.
Table 1
11.3. 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).
Recommended replacement cycle of wear parts
Table 2: "Replacement Cycle" list
Moving and discarding the unit
Contact your dealer for removing and reinstalling the total unit.
Moving units requires technical expertise.
This unit uses hydrofluorocarbon. Contact your dealer when
discarding this unit. It is required by law to collect, transport and
discard the refrigerant in accordance with the
"hydrofluorocarbon collection and destruction" regulations.
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.
