Tips for Energy Saving

Avoid
Do
NOTE
Should the power fail while the unit is running
If the power supply for this unit is temporarily interrupted the unit will automatically
resume operation (once the power is restored) with the same settings that were in
effect before the power was interrupted.
Possible Cause
1. Power failure
2. Leakage circuit breaker has tripped.
3. Line voltage is too low.
4. Operation button is turned off.
5. The remote control unit or heat pump is
malfunctioning. (ERROR and characters
such as El, PI, FI, etc., appear on the
display.)
1. Obstruction in front of condenser coil
1. Dirty or clogged air filter
2. Heat source or many people in room
3. Doors and/or windows are open.
4. Obstacle near air intake or air discharge
port
5. Thermostat is set too high for cooling (or
too low for heating).
6. (Outdoor temperature is too low.)
7. (Defrosting system does not work.)
1. Trouble in the system
Do not block the air intake and outlet of the unit. If either is obstructed, the unit will not work
well, and may become damaged.
Do not 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.
Always try to keep the air fi lter clean. A clogged fi lter will impair the performance of the unit.
To prevent conditioned air from escaping, keep windows, doors and any other openings closed.
