CONDITIONER TROUBLES
Symptom 1: The system does not operate
The air conditioner does not start immediately after the ON/OFF
button on the remote controller is pressed.
If the operation lamp lights, the system is in normal condition.
To prevent overloading of the compressor motor, the air
conditioner starts 3 minutes after it is turned ON.
If the operation lamp and the "PRE-DEF indicator(cooling and
heating type) or fan only indicator(cooling only type)" light, it
means you choose the heating model, When just starting, if the
compressor has not started, the indoor unit appears "anti-cold
