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, blind
or curtain.
DO:
●
Always try to keep the filters clean. A clogged filter will
impair the performance of the unit.
●
To prevent conditioned air from escaping, keep windows,
doors and any other openings closed.

Poor cooling or heating performance.

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).
Remedy:
1. Clean air filter to improve airflow.
2. Eliminate heat source if possible.
3. Shut them to keep the heat or cold out.
4. Remove it to ensure good airflow.
5. Set the temperature lower (or higher).
Trouble:
Clicking sound is heard from the air conditioner.

1. In heating or cooling operation, any plastic parts may expand
or shrink due to a sudden temperature change. In this event,
a clicking sound may occur.

1. This is normal, and the sound will disappear when an even
temperature is settled.
If the air conditioner does not operate in the set mode,
check that the set mode of the indoor unit is the same
of the system.
