SPECIAL REMARKS
How it works • Once the room temperature reaches the level that was set, the unit repeats the cycle of turning
on and off automatically.
• In order to prevent the humidity in the room from rising again, the indoor fan also turns off when
the unit stops operating.
• The fan speed is set to ‘‘LO.’’ automatically, and cannot be adjusted.
• ‘‘DRY’’ operation is not possible if the outdoor temperature is 59°F or less.
Heating performance
• Because this appliance heats a room by utilizing 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 heat pump, use another heating appliance in conjunction with this unit.
Defrosting • When the outdoor temperature is low, frost or ice may form on the outdoor heat exchanger coil,
reducing the heating performance. When this happens, a microcomputer-controlled defrosting
system operates. At the same time, the fan on the indoor unit stops (or runs at very low speed in
some cases) and the ‘‘STANDBY’’ indicator appears on the display until defrosting is completed.
Heating operation then restarts after several minutes. (This interval will vary slightly depending
upon the outdoor temperature and the way in which frost forms.)
(standby) on the display • For several minutes after the start of heating operation, the indoor fan will not start running (or it
will run at very low speed in some cases) until the indoor heat exchanger coil has warmed up
sufficiently. This is because a cold draft prevention system is operating. During this period, the
‘‘ ’’ (standby) indicator remains displayed.
•
(standby) remains displayed during defrosting or when the compressor has been turned off
(or when the unit is running at very low speed) by the thermostat when the system is in the
heating mode.
• Upon completion of defrosting and when the compressor is turned on again, ‘‘ ’’ (standby) will
turn off automatically as heating operation resumes.
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 the power is restored) using the same settings before the power was cut off.

CARE AND CLEANING
1. For safety, be sure to turn the air conditioner off and also to disconnect the power
before cleaning.
2. Do not pour water on the indoor unit to clean it. This will damage the internal
components and cause an electric shock hazard.
Air Intake and outlet side
(Indoor Unit)
Clean the air intake and outlet side of the indoor unit with a vacuum cleaner brush, or wipe
them with a clean soft cloth.
If these parts are stained, use a clean cloth moistened with a mild liquid detergent. When
cleaning the air outlet side, be careful not to force the vanes out of place.
1. Never use solvents or harsh chemicals when cleaning the indoor unit. Do not wipe
plastic parts using very hot water.
2. Some metal edges and the fins are sharp and may cause injury if handled
improperly; be especially careful when you clean these parts.
3. The internal coil and other components of the outdoor unit must be cleaned every
year. Consult your dealer or service center.
Air filter
(Field supplied)
The air filter collects dust and other particles from the air and should be cleaned at regular
intervals as indicated in the table below. If the filter gets blocked, the efficiency of the air
conditioner drops greatly.
Ty p e F 2
Period (depending on filter specifications)
* Low Silhouette Ducted (F2) An air filter is not provided with this air conditioner at the time of shipment. To get clean air and
to extend the service life of the air conditioner, an air filter must be installed in the air intake.
For installation and cleaning the air filter, consult your dealer or service center.
The frequency with which the filter should be cleaned depends on the environment in which
the unit is used.
