Air Filter
The air filter behind the inlet grille should be checked and
cleaned at least once every 2 weeks (or as necessary) to
maintain optimal performance of the air conditioner. If
symbol "E1" displays in the LED window, switch off and
disconnect the air conditioner from the power supply
and clean the filter.

How to remove the air filter

1.The grille may be opened from the top or bottom for
easy maintenance after installation.
2. Open the inlet grille by pulling off the exposed door on
the bottom or top of the unit (based on installation).
3. Pull the tab slightly to release the filter. Pull the filter in
the same direction as the opening.
4. Clean the filter with warm, soapy water. The water
should be below 40 C to prevent distortion of the filter.
5. Rinse off and gently shake off excess water from the
filter. Allow the filter to dry before replacing it. To prevent
distortion of the filter, do not dry in direct sunlight.
Drainage
To meet different requirement of different type of air
conditioner, there are two kinds of methods for your
choice to treat the condensed water.
For Cooling Only Models:
You can choose back drainage or non-drainage. See
the following procedures to perform back drainage:
1. Fit the seal onto the drain joint (which provided with
your air conditioner accessory).
2. Remove the rubber plug from the back of the unit.
3. Attach the drain joint to the back of the cabinet
where you remove the plug and rotate 90 to securely
assemble them.
4. Connect the drain joint with a extension drain hose
(Locally purchased)
To adjust vertical air flow direction, adjust any one of the
horizontal louvre blades. When adjusting the horizontal louver
blades up or down, always keep the top or bottom blades
horizontal. This can effectively prevent water droplets condensing
on the front panel of the unit.
