Operation Tips
The following events may occur during normal operation.
1. The compressor will not restart immediately after being stopped.
• To protect the compressor, it cannot restart for 3-4 minutes after it stops.
2. The indoor unit produces a white mist.
• The unit may generate white mist during cool mode if the room has a high relative humidity and there is
a large temperature difference between the air inlet and air outlet.
• The unit may produce white mist during heat mode after defrosting because of the moisture generated.
3. The air conditioner produces a low noise.
• The air conditioner may produce a low hissing sound when the compressor is running or has just stopped
running. The sound is caused by the refrigerant flowing or coming to a stop.
• The air conditioner may produce a low squeaking noise when the compressor is running or has just
stopped running. The sound is caused by heat expansion and cold contraction of the plastic parts in the
unit when the temperature changes.
• The louver may produce a noise as it returns to its original position when the air conditioner is turned on.
4. The indoor unit blows out dust.
• It is normal for the air conditioner to blow out dust when it has not been used for a long time or during
first use of the unit.
5. The indoor unit produces an unusual smell.
• The indoor unit may give off smells absorbed from building material, furniture or smoke.
6. The air conditioner switches to fan-only mode from cool or heat mode.
• When the indoor temperature reaches the temperature setting on the air conditioner, the compressor will
stop automatically, and the air conditioner will switch to fan-only mode. The compressor will start again
when the indoor temperature rises or falls.
7. Condensation forms on the indoor unit.
• Condensation may form on the indoor unit during cool mode if relative humidity is higher than 80%.
To reduce condensation, adjust the horizontal louver to the maximum air outlet position and select high
fan speed.
8. A power failure during operation stops the unit completely.
• When the power is restored, the auto-restart function restarts the unit with all the previous settings
preserved by the memory function.
9. The unit malfunctions without apparent cause.
• Lightning or a signal from a wireless phone may cause the unit to malfunction. Disconnect the unit from
the power source, then reconnect it. Push the on/off button on the remote controller to restart operation.
