1. The electrostatic air purifying and deodorizing filter
should be replaced once every 6 months or when the
filter changes color to brownish, whichever is sooner.
2. Used dusty filters should be disposed and shouldn't be
reused, even if it has been cleaned and washed.
• Disconnect from the main power supply before servicing the air conditioner unit.
• DO NOT pull out the power cord when the power is ON. This may cause serious electrical shocks which may result
in fire hazards.
If there is a power cut when the unit is operating, it will automatically resume the same operating mode when the power is
restored. (Applicable only to units with this feature.)
Before turning off the power supply, set the remote controller's ON/OFF switch to the "OFF" position to prevent the
nuisance tripping of the unit.
If this is not done, the unit's fans will start turning automatically when power resumes, posing a hazard to service
personnel or the user.
The unit with 3 phase Compressor can only rotate in one direction. For this reason, a protective device (phase protector) is
fitted to prevent incorrect wiring of the electrical phases. When the three phases are not connected correctly, the phase protector
operates, and the unit will not start. This devise is located in the control box of the outdoor unit.
The following table shows the LED indicator light for phase protector under normal operation and fault conditions.

3. The filter is a consumable part which you can purchase
from your air conditioner dealer.
4. Use the new filter immediately once it has been taken
out from its sealed packing. Do not unpack the new
filter too early before it is actually used as this may
decrease its deodorizing effect.
