Typical Operational Occurrences
Thefollowingeventsmayoccurduringnormaloperation.
1. Protection of the air conditioner.
Compressor protection
•Iftheunitisstoppedandthenimmediatelyrestartedagain,thecompressorwillnotoperateforabout
3 minutes in order to protect the compressor.
Anti-cold air (heat pump models only)
•TheunitisdesignednottoblowcoldairinHEATmode,whentheindoorheatexchangerisinoneof
thefollowingthreesituationsandthesettemperaturehasnotbeenreached.

B)Defrostingisoccurring
C)Lowtemperatureheatingisoccurring
Defrosting (Cooling and heating models only)
•Theindoororoutdoorfanstoprunningwhendefrosting(heatpumpmodelsonly).
•Frostmayaccumulateontheoutdoorunitduringheatcyclewhenoutdoortemperatureislowandhu-

•Defrosttimemayvaryfrom4to10minutesaccordingtotheoutdoortemperatureandtheamountof
frostbuildupontheoutdoorunit.
2. Mist or steam are being emitted
•Awhitemistmayemitfromtheindoorunitduetoalargetemperaturedifferencebetweenairinletand
