Measure: Notify your dealer and report the malfunction code.

If the system does not properly operate except for the above
mentioned cases and none of the above mentioned malfunctions is
evident, investigate the system according to the following
procedures.

If the system does not operate at all

Check if there is no power failure.
Wait until power is restored. If power failure occurs during
operation, the system automatically restarts immediately after
the power supply is recovered.

Check if no fuse has blown or breaker has worked. Change the
fuse or reset the breaker if necessary.

2

If the system goes into fan only operation, but as soon as it
goes into heating or cooling operation, the system stops

Check if air inlet or outlet of outdoor or indoor unit is not blocked
by obstacles. Remove any obstacle and make it well-ventilated.

Check if the remote controller display shows "

clean the air filter). (Refer to "Maintenance" in the indoor unit
manual.)

The system operates but cooling or heating is insufficient

Check if air inlet or outlet of outdoor or indoor unit is not blocked
by obstacles.

Remove any obstacle and make it well-ventilated.

Check if the air filter is not clogged. (Refer to "Maintenance" in
the indoor unit manual.)

Check the temperature setting.

Check the fan speed setting on your remote controller.

Check for open doors or windows. Shut doors and windows to
prevent wind from coming in.

Check if there are too many occupants in the room during
cooling operation

Check if the heat source of the room is excessive.

Check if direct sunlight enters the room. Use curtains or blinds.

Check if the air flow angle is proper.

If after checking all above items, it is impossible to fix the problem
yourself, contact your dealer and state the symptoms, the complete

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.

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:

1.

Normal use without frequent starting and stopping of the unit.
Depending on the model, we recommend not starting and

TEST

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.

Table

Depending on the content of the maintenance and
inspection contract, inspection and maintenance
cycles may in reality be shorter than listed.
