Cause
• The unit is in defrost mode, and the melted frost is
drained from the outdoor unit.
• The timer setting repeats daily once set.
• The delay is a protection to the unit's compressor.
• To avoid unintended cooling effect.
• This helps to remove the surrounding odour.
• Extraction of remaining heat from the indoor unit
(maximum 30 seconds).
• This may be due to damp smell emitted by the wall,
carpet, furniture or clothing.
• Changes of temperature caused the expansion/
contraction of the unit.
• Refrigerant flow inside the unit.
• Condensation effect due to cooling process.
• Condensation or evaporation occurs on pipes.
• Discoloration is subject to material types used in plastic
parts, accelerated when exposed to heat, sun light, UV
light or environmental factor.
