SPECIAL REMARKS
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.
