Care and Cleaning
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 15 °C 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.
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 water. 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
periodically. Consult your dealer or service center.
