Is the Timer correctly used?

Is Temp. setting suitable?
●
Were inlet and outlet vents obstructed?

●
Condensing water over flowed.
●
The connection position of indoor unit drainage
●
pipe is loosed.
When the unit is running in COOL mode, the
●
pipe and connection of pipe would be
condensed due to the water cooled down.
During heating or defrosting operation, the
●
melted water will blow out.
The water adhered on the heat exchanger
●
will drop during heating operation.
The sound of fan or compressor relay is
●
switching on or off.
When the defrosting is started or stop running,
●
it will sound. That is due to the refrigerant
flowed to the reversed direction.
