ADDITIONAL NOTES ON

OPERATION

OPERATING TEMPERATURE RANGE

		INDOOR TEMP.	OUTDOOR TEMP.
HEATING	upper limit	27˚C	24˚C
HEATING	lower limit	–	–20˚C
	lower limit	–	–20˚C
COOLING	upper limit	32˚C	43˚C
COOLING	lower limit	21˚C	–10˚C
	lower limit	21˚C	–10˚C

•The built-in protective device may prevent the unit from operating when used out of this range.

•Condensation may form on the air outlet if the unit operates continuously in the COOL or DRY mode when humidity is over 80 percent.

WHEN POWER FAILURE OCCURS

This unit has a memory function to store settings when a power failure occurs.

After power recovery, the unit will automatically re- start in the same settings which were active before the power failure, except for timer settings.

If the timers were set before a power failure, they will need to be re-set after power recovery.

PREHEATING FUNCTION

In the HEAT operation, the indoor fan may not start for two to ﬁve minutes after the unit is turned on to prevent cold air from blowing out of the unit.

DE-ICING FUNCTION

•When ice forms on the heat exchanger in the outdoor unit during the HEAT operation, an automatic de-icer provides heat for about 5 to 10 minutes to remove the ice. During de-icing, the inside and outside fans stop operating.

•After de-icing is completed, the unit automatically resumes operation in the HEAT mode.

HEATING EFFICIENCY

•The unit employs a heat pump that draws heat from the outside air and releases it into the room. The outside air temperature therefore greatly affects the heating efﬁciency.

•If the heating efﬁciency is reduced due to low outside temperatures, use an additional heater.

•It takes time to warm up and heat the entire room because of the forced air circulation system.
