Cause Cause
• Condensation effect due to cooling process.
• Refrigerant fl ow inside the unit.
• This may be due to damp smell emitted by the wall, carpet, furniture or
clothing.
• This helps to remove the surrounding odours.
• The delay is a protection to the unit's compressor.
• Condensation or evaporation occurs on pipes.
• The timer setting repeats daily once set.
• To avoid unintended cooling effect.
• Changes of temperature cause the expansion/contraction of the unit.
• This happens when the room temperature reaches the set temperature,
operation switches to FAN mode and the humidity increase.
• This is due to changes infl ow of refrigerant gas when operation stops
and starts.
• Discharging heat is in process. Operation will stops automatically after
approximately 60 seconds.
• The unit is in defrosting mode, and the melted frost is drained from the
outdoor unit.
• The unit is warming up to provide warm air.
