10 IMPORTANT ANY SEALED SYSTEM REPAIRS TO COOL-ONLY MODELS REQUIRE THE INSTALLATION OF A LIQUID LINE DRIER. ALSO, ANY SEALED SYSTEM REPAIRS TO HEAT PUMP MODELS REQUIRE THE INSTALLATION OF A SUCTION LINE DRIER. the liquid refrigerant leaves the metering device entering the evaporator coil. As it ente...

Page 12 - REFRIGERANT CHARGING; METHOD OF CHARGING

12 NOTE: In order to access the sealed system it will be necessary to install Schrader type ﬁ ttings to the process tubes on the discharge and suction of the compressor. Proper refrigerant recovery procedures need to be adhered to as outlined in EPA Regulations. THIS SHOULD ONLY BE ATTEMPTED BY QUAL...

Page 13 - REFRIGERANT CHARGING cont’d

13 An undercharged system will result in poor performance (low pressures, etc.) in both the heating and cooling cycle. Whenever you ser vice a unit with an under charge of refrigerant, always suspect a leak. The leak must be repaired before charging the unit. To check for an undercharged system, tur...

Page 14 - RESTRICTED REFRIGERANT SYSTEM

14 A quick check for either condition begins at the evaporator. With a partial restriction, there may be gurgling sounds at the metering device entrance to the evaporator. The evaporator in a partial restriction could be partially frosted or have an ice ball close to the entrance of the metering dev...
