1. Remove obstruction.
Poor cooling (or heating)
performance.
1. Dirty or clogged air filter.
1. Clean air filter to improve the
airflow.
2. Heat source or many people in
room.
2. Eliminate heat source if possible.
3. Doors and/or windows are open.
3. Shut them to keep the heat (or
cold) out.
4. Obstacle near air intake or air
discharge port.
4. Remove it to ensure good airflow.
5. Thermostat is set too high for
cooling (or too low for heating).
5. Set the temperature lower (or
higher).
6. (Defrosting system does not work.)

Avoid
•
Do not block the air intake and outlet of the unit. If either is
obstructed, the unit will not work well, and may be 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.
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.
Should the power fail while the unit is running
If the power supply for this unit is temporarily cut off, the unit will automatically
resume operation once power is restored using the same settings before the
power was cut off.
