Cause
• Condensation effect due to cooling process.
• Refrigerant flow inside the unit.
• This may be due to damp smell emitted by the wall,
carpet, furniture or clothing.
• This helps to remove the surrounding odour.
• The delay is a protection to the unit's compressor.
• Condensation or evaporation occurs on pipes.
• The timer setting repeats daily once set.
• This is a preliminary step in preparation for the
operation when the ON timer has been set.
• Changes of temperature caused the expansion/
contraction of the unit.
• Discoloration is subject to material types used in plastic
parts, accelerated when exposed to heat, sun light,
UV light, or environmental factor.
Check
• Set the temperature correctly.
• Close all doors and windows.
• Clean or replace the filters.
• Clear any obstruction at the air inlet and air outlet vents.
