Discharge the refrigerant system using a FreonTM Recovery
System. If there is no valve to attach the recovery system,
: REFRIGERANT FLOW install one (such as a WATCO
Leave the valve in place after servicing the system. Do not vent FreonTM into the atmosphere.
The following is a brief description of the important components and their function in what is called the refrigeration system. Reference should made to figure 17 to follow the refrigerating cycle and the flow of the refrigerant in the cooling cycle.
