7. FOLLOWING SYMPTOMS ARE NOT AIR
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.
Symptom 3: White mist comes out of a unit
Symptom 4: Noise of air conditioners cooling
When humidity is high during cooling operation If the interior of
an indoor unit is extremely contaminated,the temperature
distribution inside a room becomes uneven. It is necessary to
clean the interior of the indoor unit.Ask your dealer for details on
cleaning the unit.This operation requires a qualified service
person.
When the system is changed over to heating operation after
defrost operation Moisture generated by defrost becomes
steam and is exhausted.

cooling operation or at a stop.
When the drain pump (optional accessories) is in operation,this
noise is heard.
A "pishi-pishi" squeaking sound is heard when the system stops
after heating operation.
Expansion and contraction of plastic parts caused by
temperature change make this noise.
Symptom 5: Dust comes out of the unit
Symptom 6: The units can give off odours
When the unit is used for the first time in a long time.
This is because dust has gotten into the unit.
When the tone of operating noise changes.
