6. ge For correct refrigerant amount please refer to the rating label at the back of the unit The deviation should be within 3g Re switch the unit after the temperature drops down Discharge temperature is too high Refrigerant is too less or has been leaked Condenser too dusty Air return of the condenser is blocked Air supply of the condenser is blocked R P M of down motor too low Release the remained refrigerant vacuum the unit at least over 755mmHg Recharge the unit For correct refrigerant amount please refer to the rating label at the back of the unit The deviation should be within 3g Clean the condenser Remove the blockade Remove the blockade Discharge pressure too low Room temperature too low Refrigerant is too less or has been leaked R P M of the down motor too high thus the air volume is too big This is normal situation please increase the room temperature Release the remained refrigerant vacuum the unit at least over 755mmHg Recharge the unit For correct refrigerant amount please refer to the rating label at the back of the unit The deviation should be within 3g Adjust the R P M of the down motor to the acceptable one How to REPLACING THE COMPRESSOR Take off the overload protector and wires of the compressor Take off the suction and discharging tubes Unfasten the screws on the compressor Take off the accessories for the compressor 40
7. nt is correct DEY Make sure the wire distribution is correct according to the supplied diagram Make sure the pipes tubes are in the right position do not hit with the other parts Make sure the insulation resistance between the plug and grounding is over 2MQ Make sure the whole cooling system is of no leakage Make sure the fan operates normally and does not hit the other parts Make sure the compressor can operate normally without abnormal noise Set the machine to max cooling and high ventilation after 30 minutes put your hand on the evaporator to check it is making the cooling or not Measure the temperature at the air inlet and outlet make sure the temperature difference is over 10 C Make sure the water tray water pipe inside the machine are of no leakage and well installed
