Cracking noise:
• This is the sound of friction caused by expansion and/
or contraction of panel or other parts due to the change
of temperature.
The unit can not be started up:
• Is the power cut off?
• Is the power plug loose? (If applicable )
• Is the circuit protection device tripped off?

replace them if necessary.
• Check if the remote controller is damaged.
• The humidity is high.
Water leakage of FCU.
• Condensate overflows.
• Drain hose is loose.
Noise from FCU.
The noise emitted when the fan is switching on or off.
• In HEAT mode, when the temperature of FCU heat
exchanger is very low, air flow is stopped in order to
prevent cold air.
FCU can not blow air:
• In COOL mode, when the temperature of FCU heat
exchanger is very high, air flow is stopped in order to
prevent hot air.
