HINTS FOR ECONOMICAL OPERATION
The following should be noticed to ensure an economical operation. (Refer to corresponding chapter
for details)
Adjust the air flow direction properly to avoid winding toward your body.
Adjust the room temperature properly to get a comfortable situation and to avoid supercooling and
superheat.
In cooling, close the curtains to avoid direct sunlight.
To keep cool or warm air in the room, never open doors or windows more often than necessary.
Set the timer for the desired operating time.
Never put obstructions near the air outlet or the air inlet. Or it will cause lower efficiency, even a
sudden stop.
If you don't plan to use the unit for a long time, please disconnect power and remove the batteries
from the remote controller. When the power switch is connected, some energy will be consumed,
even if the air conditioner isn't in operation. So please disconnect the power to save energy. And
please switch the power on 12 hours before you restart the unit to ensure a smooth operation.
A clogged air filter will reduce cooling or heating efficiency, please clean it once two weeks.
