OPERATION TIPS
The following eventsmay occur during normal operation.
1. Protection ofthe air conditioner.
Compressor protection
The compressor can'trestart for 3minutes after itstops.
Anti-cold air (Cooling and heating models only)
The unit isdesigned not toblow cold airon HEATmode, when theindoor heat
exchanger is inone of the following three situations and the settemperature has not
been reached.
A) Whenheating has just starting.
B) Defrosting.
C) Low temperatureheating.
The indoor oroutdoor fan stoprunning when defrosting(Cooling and heating models
only).
Defrosting (Cooling and heatingmodels only)
Frost may begenerated on the outdoor unit during heat cycle whenoutdoor temperature
is low andhumidity is high resulting in lower heating efficiency ofthe air conditioner.
During this conditionair conditioner will stop heating operation and start defrosting
automatically.
The time todefrost may varyfrom 4 to10 minutes according to the outdoor temperature
and the amountof frost build up on the outdoor unit.
2. Awhite mist coming out from theindoor unit
Awhite mist may generate due to a large temperaturedifference between airinlet and
air outlet onCOOL mode in an indoor environment that has a high relativehumidity.
Awhite mist may generate due to moisture generated fromdefrosting process when
the air conditionerrestarts in HEAT mode operationafter defrosting.
3. Low noiseof the air conditioner
Youmay hear a low hissing sound when the compressoris running or has just stopped
running. This soundis the soundof the refrigerantflowing or coming to a stop.
Youcan also hear a low "squeak" sound when thecompressor is running or has just
stopped running. Thisis caused byheat expansion andcold contraction of the plastic
parts in theunit when the temperature is changing.
Anoise may be heard due to louver restoring toits original position when power is first
turned on.
4. Dust isblown out from the indoor unit.
This is anormal condition whenthe air conditionerhas not been used for a long time or
during first useof the unit.
5. Apeculiar smell comes out from theindoor unit.
This is causedby the indoorunit giving offsmells permeated frombuilding material, from
furniture, or smoke.
6. The airconditioner turns toFAN onlymode from COOLor HEAT(For cooling and
heating models only)mode.
When indoor temperaturereaches the temperaturesetting on air conditioner, the
compressor will stopautomatically, andthe air conditionerturns to FAN only mode. The
compressor will startagain when the indoor temperature rises on COOL mode or fallson
HEAT mode (For coolingand heating models only) to the set point.
