2 Ensure that the 2 refrigerant pipes are insulated to prevent condensation.
3 Refrigerant pipe bending radius must be 4" (100 mm) or more.
Caution
thickness may cause dew drippage.
Warning:
When pumping down the refrigerant, stop the compressor before disconnect-
ing the refrigerant pipes. The compressor may burst and cause injury if any
foreign substance, such as air, enters the system.
