Malfunctioning Cause What must be done?
The unit does not cool or heat the
room well, while air escapes from
the conditioner.
Incorrect temperature setting. Set the temperature correctly.
The air lter is clogged. Clean the air lter.
The doors or windows are open. Close the doors or windows.
The air inlet or outlet vents of the indoor
or outdoor units are blocked.
First, remove the obstructions and then
re-start the unit.
Temperature setting may be higher than
the ambient room temperature.
Lower the temperature setting.
Excessive heat generated by the
sunlight.
Close your windows or curtains.
Low cooling caused by leakage or
prolonged use.
Check for possible leakage, contact
the assistance service if that occurs.
The outdoor temperature is lower than
7°C.
Check for possible leakage, contact
the assistance service if that occurs.
Low refrigerant due to leak or long-
term use.
Check for possible leakage, contact
the assistance service if that occurs.
The unit starts and stops
frequently
There’s too much or too little refrigerant
in the system.
Check for possible leakage, contact
the assistance service if that occurs.
There is air, incompressible gas or
foreign material in the refrigeration
system.
Contact the assistance service.
System circuit is blocked. Contact the assistance service.
The compressor is broken. Contact the assistance service.
The voltage is too high or too low. Install a manostat to regulate the volt-
age; contact the assistance service.
5.3 - FUNCTIONAL ASPECTS NOT TO BE MISTAKEN FOR ANOMALIES
The following events may occur during normal operation:
1. PROTECTION OF THE AIR CONDITIONER.
a. The compressor will not re-start for 3 minutes after it has been switched off.
- The unit is designed not to blow cold air in HEATING mode, when the internal heat exchanger is in one
of the following conditions and the temperature set has not been reached.
- When heating has just been started.
- Defrosting.
- Low temperature heating.
b. The indoor or outdoor fans stop running during defrosting.
- Frost may form on the outdoor unit during the heating cycle, when the outdoor temperature is low and
humidity is high, which may cause lower heating efciency or air conditioning.
- If this occurs, the air conditioner will stop heating mode and will automatically activate the defrosting
function.
- The time required to perform defrosting can vary from 4 to 10 minutes, depending on the outdoor
temperature and the amount of frost that has formed on the outdoor unit.
2. WHITE MIST ESCAPES FROM THE INDOOR UNIT
- White mist may be generated due to the large temperature difference between the inlet air and the outlet
air in COOLING mode in indoor environments with high relative humidity.
- The white mist may be generated by the humidity produced by the defrosting process when the air
conditioner re-starts in COOLING mode after defrosting.
