Nominal cooling capacity of outdoor unit is tested under the condition that outdoor ambient dry/wet bulb
temperature is 35°C/24°C.Actual max. Output capacity depends on outdoor ambient temperature and
connection method, which may differ from nominal value. According to refrigeration system design and
operation requirement, this outdoor unit should work with indoor units with corresponding total capacity, which
ensures optimal performance and safe operation. To meet users' demand, this unit is specially designed that
unit can work even though required total capacity of indoor units exceeds nominal value. Under this condition,
actual output capacity of single indoor unit may be attenuated and less than nominal value. We disclaim all
responsibility for malfunct
ion caused by users’ noncompliance of this installation and operation instructions.
