• This may be due to damp smell emitted by the wall,
carpet, furniture or clothing.
• This helps to remove the surrounding odour.
• Extraction of remaining heat from the indoor unit
(maximum 30 seconds).
• The delay is a protection to the unit's compressor.
• Condensation or evaporation occurs on pipes.

achieve the desired temperature on time.
• Changes of temperature caused the expansion/
contraction of the unit.

around the air conditioner frequently).

parts, accelerated when exposed to heat, sun light, UV
light or environmental factor.
