CONDITIONER TROUBLES

Symptom 1: The system does not operate

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 , 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.

Symptom 2: Change into the fan mode during

cooling mode

In order to prevent the indoor evaporator frosting, the system will change into fan mode automatically, restore to the cooling

Mini MVD V4+

Symptom 4.2: Indoor unit, outdoor unit

A continuous low hissing sound is heard when the system is in operation.

This is the sound of refrigerant gas flowing through both indoor and outdoor units.

A hissing sound which is heard at the start or immediately after stopping operation or defrost operation.

This is the noise of refrigerant caused by flow stop or flow change.

Symptom 4.3: Outdoor unit

When the tone of operating noise changes.

This noise is caused by the change of frequency.

Symptom 5: Dust comes out of the unit

When the unit is used for the first time in a long time.

This is because dust has gotten into the unit.

Symptom 6: The units can give off odours

The unit can absorb the smell of rooms, furniture, cigarettes, etc., and then emit it again.

Symptom 7: The outdoor unit fan does not

spin.

During operation. The speed of the fan is controlled in order to optimize product operation.

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 3.1: Indoor unit

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 erson

Symptom 3.2: Indoor unit, outdoor unit

When the system is changed over to heating operation after defrost operation Moisture generated by defrost becomes steam and is exhausted.

Sptom 4: Noise of air conditionerscooling

Symptom 4.1: Indoor unit

A continuous low "shah" sound is heard when the system is in cooling operation or at a stop.

When the drain pump (optional accessories) is in operation,this noise is heard.
