10. Operating Guide
The cleaning and replacement of the filter is only permitted to be done by the professionals. Before
open the grille to clean the filter, please cut off the power supply and wait unit the fan motor stops.
1. The temperature should not be set lower than what you need, otherwise it would result in increased
energy cost.
2. To distribute cool air throughout the room, adjust the air flow direction as shown by the arrows (see
the picture).
3. Clean the air filter every week for higher efficiency.
4. Close the window and door while operating the unit to prevent leakage of cooled air to save energy.
5. Draw close the curtains or close glass windows when cooling to prevent heat load from sun light
which may cause more electricity cost.
6. In case of ineffective ventilation, open the window to ventilate the room air once in a while but not
too long since cooled air will be uselessly drained out.
