Troubleshooting

Symptom Cause
POWER indicator blinks before the unit is switched on. • This is the

preliminary step to prepare for the TIMER operation after it has been set.

• When Timer is set ON, the unit may start earlier (up to 15 minutes) before the actual set time to achieve the desired temperature on time.

TIMER indicator is always ON.| • When Timer has been set, the Timer setting repeats daily.
Operation is delayed a few minutes after restarting.| • The delay is a protection to the unit’s compressor.
Indoor fan stops occasionally during automatic fan speed setting.| • This is to help remove the surrounding odour.
The room has a peculiar odour.| • This may be due to damp smell emitted by the wall, carpet, furniture or clothing.
Cracking sound during operation.| • Changes in temperature caused the unit to expand and contract.
Water flowing sound during operation.| • Refrigerant flow inside the unit.
Mist emerges from indoor unit.| • During cooling operation, the discharged cold air may condense to water vapour.
Outdoor unit emits water or steam.| • During cooling operation, condensation occurs on

cold pipes and the condensed water may drip from the outdoor unit.

Discoloration of some plastic parts.| • Discoloration is subjected to the types of materials used in plastic parts. It is accelerated when exposed to heat, sun light, UV light or environmental factors.

When

  • The remote control is missing or a malfunction has occurred
  1. Raise the front panel.
  2. Press AUTO OFF/ON once to use in AUTO mode.
  3. Press AUTO OFF/ON until you hear 1 beep, then release to use in forced COOL mode.
  4. Press AUTO OFF/ON again to turn off the unit.

The indicators are too bright

  • To dim or restore the indicators’ brightness on the unit, press on the remote for 5 seconds.

Check the batteries

  • Check that there is no obstruction around the air inlets and outlet vents.
  • Use AUTO OFF/ON on the unit to select COOL mode. For details, refer “The remote control is missing or a malfunction has occurred” above. After 15 minutes of operation, it is normal to have the following temperature difference between the air inlet and outlet vents: COOL: ≥ 8 °C / 14.4 °F

The units will not be used for an extended period

  • Turn off the power supply and unplug the unit.
  • Remove the batteries from the remote control.

NON SERVICEABLE CRITERIAS
TURN OFF THE POWER SUPPLY AND UNPLUG THE UNIT. Then consult an authorised dealer in the following conditions:
