•Is the refrigerant level too high?
• Is the heat exchanger dirty or clogged?
(1) The compressor’s speed drops when all the following conditions are met (151~251). In the case of the 301~601, expansion valve control is performed.
1Outdoor heat exchanger temperature: A˚C or higher
2Outdoor air temperature: 41ºC or higher
3The outdoor unit’s fan runs at 7 speed (UHi)(1) continuously for 30 seconds or longer.
(2)Control is cancelled when the temperature drops to BºC or lower.
