• Temperature ranges suitable for unit operation are as follows.
• When the unit operates above or below these conditions for a long time, system diagnostics may detect a
malfunction and the unit will not operate properly.
• If the unit operates for a long time under abnormal situation of extremely high humidity, condensed water may
drip from the unit.
Time Delay
• If the operating mode changes from COOL and DRY to HEAT,
there will be 3 minutes time delay for 53G100HF,HP/53G150HF,HP/53G225HF-1 or 5 minutes time delay for
53G250HF-1,HP-1, between compressor turning off and turning on including starting the heat operation.
• If the operating mode changes from Heat to Cool and Dry, there will be 3 minutes time delay for
53G100HF,HP/53G150HF,HP/53G225HF-1/53G250HF-1,HP-1.
• When heating operation starts, hot air delivery might be delayed due to a warm up period.
Minimum Operation Time
• In normal operation, there is a minimum operation time of 3 minutes between compressor turning on and turning
off.
Heating Features
• When the unit starts in the heating mode, there will be a preheating period before the unit is ready to deliver
warm air.
• When the outdoor temperature is low, the heating capacity will be reduced. If the room air is not warm enough
during severe winter conditions, use additional heating devices.
Defrost Operation
• In the heating mode, when the outdoor coil is frosted, the indoor fan and outdoor fan will turn off while the
compressor will turn on to remove the frost on the outdoor coil.
• The defrost mode stops after 10 minutes or when the outdoor coil temperature is greater than 18
°
c.
• When the power is off, the defrost operation is automatically conducted depending on frost
accumulation on the outdoor coil.
Auto Recovery
• When the electricity fails while the unit is operating, the unit memorizes the operating condition, and it will
start operation automatically when the electricity is restored.
• When you leave home during an electricity failure, please unplug the power cord, or the unit will automatically
restart in your absence.
