OPERATION TIPS
Thefollowing eventsmay occur during normal operation.
1. Protection of theair conditioner.
Compressorprotection
Thecompressorcan'trestart for3minutes afteritstops.
Anti-cold air(Cooling andheating models only)
The unit is designed not to blow cold air in “HEAT” mode, when the indoor heat exchanger is in
one of thefollowing threesituations and theset temperature has not been reached.
A) When heating has juststarted.
B) Defrosting is occurring.
C) Low temperature heating is occurring.
The indoor and/or outdoor fan stop running when defrosting (Cooling and heating models only).
Defrosting (Cooling andheating models only)
Frostmay be generated on the outdoor unit during heat cycle when outdoor temperatureislow
and humidityishigh resulting in lower heating efficiencyofthe air conditioner.
During this condition the air conditioner will stop heating function and start defrosting automatically.
Thetimetodefrost mayvaryfrom4to 10 minutes according to the outdoor temperature and
theamount of frost buildup on the outdoor unit.
2. Awhitemistcoming out from the indoor unit
3. Low noiseofthe airconditioner
A low hissing sound may be heard when the compressor is running or has just stopped running.
This sound is thesound of therefrigerant flowing or coming toastop.
A low "squeak" sound may be heard when the compressor is running or has just stopped running.
This is caused by heat expansion and cold contraction of the plastic parts in the unit when thetemper-
atureischanging.
Anoisemay be heard due to louver restoring to itsoriginal position when power is first turned on.
OperationTips
18
A white mist may be generated due to a large temperature difference between air inlet and air outlet in
“COOL” mode in an indoor environment that has a high relative humidity.
A white mist may be generated due to moisture generated from defrosting process when the air
conditioner restarts in “HEAT” mode operation after defrosting.
Reconnect power supply and reinstall batteries in remote control.

11
4. Dust is blown out from the indoor unit.
This is a normal condition when the air conditioner has not been used for a long time or during first
use of the unit.
5. Apeculiar smellcomes out from the indoor unit.
This is caused by the indoor unit giving offsmells permeated from building material, from furniture,
or smoke.
6. The air conditioner turns to “FAN” only mode from “COOL” or “HEAT” (For cooling and heating
models only) mode.
When indoor temperature reaches the temperature setting on air conditioner, the compressor will stop
automatically, and the air conditioner turns to “FAN”only mode. The compressor will start again when the
indoor temperature rises on “COOL” mode or falls on “HEAT”mode (For cooling and heating models only)
to the set temperature.
OPERATION TIPS
7. Dripping watermay accumulate on the surface of the indoor unit when cooling in a high relative humidity
(relative humidityhigher than 80%). Adjust the horizontal louver to themaximum air outlet position and
select HIGH fanspeed.
8. Heating mode (For cooling andheating models only)
Theair conditioner drawsinheat from the outdoor unit and releases it viathe indoor unit during heating
operation. When the outdoor temperaturefalls, heat drawninbythe airconditioner decreases accordingly.
At thesametime, heat loading of theair conditioner increases due to larger difference between indoor and
outdoor temperature. If acomfortabletemperaturecan'tbeachievedbythe unit we suggest
using a supplemental heating device.
9. Auto-restartfunction
Powerfailure during operation will stop the unitcompletely.
Forthe unit without Auto-restartfeature, when the power restores,the “OPERATION”indicator on the indoor
unitstartsflashing. To restartthe operation, pushthe “ON/OFF” button on the remote control. For the unit
withAuto-restartfeature, when the power restores,the unitrestarts automatically withall theprevious settings
preservedbythe memory function.
10. Lightning or awirelesstelephone operating nearby maycausethe unittomalfunction.
Disconnectthe unit with power and then re-connectthe unit with power again. Push the “ON/OFF” button on
theremotecontroltorestart operation.
