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 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.
