Tips for Energy Saving
Do not
•
Block the air intake and outlet of the unit. If they are obstructed,
the unit will not work well, and may be damaged.
•
Let direct sunlight into the room. Use sunshades, blinds or curtains.
If the walls and ceiling of the room are warmed by the sun, it will
take longer to cool the room.
Do
•
Always try to keep the air filter clean. (Refer to ‘‘Care and Cleaning’’.)
A clogged filter will impair the performance of the unit.
•
To prevent conditioned air from escaping, keep windows, doors and
any other openings closed.
