Air filter
The air filter collects dust and other particles from the air and should
be cleaned once every 6 months.
If the filter gets blocked, the efficiency of the air conditioner drops
greatly.
NOTE
The frequency with which the filter should be cleaned depends on
the environment in which the unit is used.
How to remove the filter
1.
Slide the two latches of the air intake grille with your thumbs in the
direction of the arrow to open the grille.

CAUTION
Care: After a prolonged idle period
Check the indoor and outdoor unit air intakes and outlets for
blockage; if there is a blockage, remove it.
Care: Before a prolonged idle period
• Operate the fan for half a day to dry out the inside.
• Disconnect the power supply and also turn off the circuit breaker.
• Clean the air filter and replace it in its original position.
• Outdoor unit internal components must be checked and cleaned
periodically.
Contact your local dealer for this service.
Safety cord
• When cleaning the air filter, never
remove the safety cord. If it is
necessary to remove it for servicing
and maintenance inside, be sure to
reinstall the safety cord securely (hook
on the grille side) after the work.
• When the air intake grille has been
opened, rotating parts (such as the
fan), electrically charged areas, etc. will
be exposed in the unit's opening. Bear
in mind the dangers that these parts
and areas pose, and proceed with the
work carefully.
• Periodically check the outdoor unit to
see if the air outlet or air intake is
clogged with dirt or soot.
