SPECIAL REMARKS

‘‘DRY’’ ( ) Operation

How it works?

• Once the room temperature reaches the level that was set, the unit’s operation frequency is changed automatically.

• During DRY operation, the fan speed automatically runs at lower speed for providing a comfortable breeze.

• ‘‘DRY’’ operation is not possible if the indoor temperature is 59 °F or less.

Heating ( ) Operation

Heating performance

• When High power operation , Fan speed Automatic operation

, HIGH or MEDIUM has been changed to Fan speed

LOW , Quiet operation or Night Setback , the fan speed may not be reduced to the desired setting immediately but rather it may be reduced slowly in steps due to the operating status of the air conditioner. (A maximum of 5 minutes are required for the change to be completed.)

• Because this air conditioner heats a room by drawing in the heat of the outside air (heat pump system), the heating efficiency will fall off when the outdoor temperature is very low. If sufficient heat cannot be obtained with this air conditioner, use another heating appliance together with it.

Defrosting

• When the outdoor temperature is low, frost or ice may form on the heat exchanger coil, reducing heating performance. When this happens, a microcomputer defrosting system operates. At the same time, the fan on the indoor unit stops and the OPERATION lamp lights red and orange alternately until defrosting is completed.

Heating operation restarts after several minutes. (This interval will vary slightly depending upon the outdoor temperature and the way in which frost forms.)

Cold draft prevention

• For several minutes after the start of heating operation, the indoor fan runs at a lower speed until the indoor heat exchanger coil has warmed up sufficiently. However, the fan may remain stopped when the room temperature is low. This is because the COLD DRAFT

PREVENTION SYSTEM is in operation.

Cooling ( ) operation

• Sometimes the indoor unit may not get to the set fan speed such as

LOW under cool operation at very low outdoor temperatures due to the indoor unit being protected from ice or frost.

Power failure during operation

• In the event of power failure, the unit will stop. When the power is resumed, the unit will restart automatically in approximately

5 minutes by the remote controller.

If the remote controller is on and left in a location where the unit can receive a signal, then the unit will automatically restart in approximately 5 minutes of power being restored.

Clicking Sound

Clicking sound is heard from the air conditioner

• 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. This is normal, and the sound will soon disappear.

Remote Controller

• The remote controller sends the setting condition to the air conditioner regularly at five minute intervals.

TIPS FOR ENERGY SAVING

Avoid

• Do not block neither the air intake nor the air outlet. It may cause less performance, and may leads to malfunctions.

• 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.

ADJUSTING THE AIRFLOW

DIRECTION

1. Horizontal

The horizontal airflow can be adjusted by moving the vertical vanes with your hands to the left or right.

CAUTION

• Use the FLAP button on the remote controller to adjust the position of the flap. If you move the flap by hand, the flap position according to the remote controller and the actual flap position may no longer match. If this should happen, shut off the unit, wait for the flap to close, and then turn on the unit again; the flap position will now be normal again.

• Do not have the flap pointed down during cooling operation.

Condensation may begin to form around the air vent and drip down.

OPERATION WITHOUT THE

REMOTE CONTROLLER

CAUTION

When the humidity is high, the vertical vanes should be in the front position during the cooling or dehumidifying operation. If the vertical vanes are positioned all of the way to the right or left, condensation may begin to form around the air vent and drip down.

2. Vertical

The vertical airflow can be adjusted by moving the flap with the remote controller. Do not move the flap with your hands. Confirm that the remote controller has been turned on. Use the FLAP button to set either the sweep function or one of the six airflow direction settings.
