CONDITIONER TROUBLES
Symptom 1: The system does not operate
Symptom 2: Change into the fan mode during cooling
mode
The air conditioner does not start immediately after the ON/OFF
button on the romote 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
wind" protection because of its overlow outlet temperature.
In order to prevent the indoor evaporator frosting, the system
will change into fan mode automatically, restore to the cooling
mode after soon.
When the room temperature drops to the set temperature, the
compressor goes off and the indoor unit changes to fan mode;
when the temperature rises up, the compressor starts again. It
is same in the heating mode.
