Hints for Economical Operation
The following should be noticed to ensure optimal economical operation.
(Refer to corresponding chapter for more details)
• Adjust the air flow direction properly to avoid winding toward your body.
• Adjust the room temperature properly to maintain a comfortable temperature and to avoid supercooling or
superheating.
• While cooling, close the curtains to avoid direct sunlight.
• To keep cool or warm air in the room, refrain from opening and closing doors or windows more often than
necessary. Set the timer for the desired operating time.
• Clear any obstructions from the vicinity of the air outlet or the air inlet. Obstructions will cause lower efficiency,
or sudden stop in operation.
• If you do not plan to use the unit for a long time, disconnect the power and remove the batteries from the
remote control. When the power switch is connected, some energy will be consumed, even if the air
conditioner isn't in operation. Once you plan to use the unit again, switch the power on 12 hours before you
restart the unit to ensure a smooth operation.
• Clean the air filter bi-weekly. A clogged air filter will reduce cooling or heating efficiency.
