REPAIR OR REPLACEMENT

NOTE

The coupling half fittings (hose disconnect fittings) used for joining the interconnecting

Refrigerant R-22 metal hoses, contain a poppet valve assembly to prevent Refrigerant R-

22 loss and to keep air from entering the line when hoses are disconnected. The

following instructions apply to both the suction (low pressure) and discharge (high

pressure) couplings.

Male Coupling Half

All repairs other than tightening of screw joints will require disassembly and replacement of

some parts. When the half couplings are disassembled for any reason, the O-rings and gaskets

should be replaced.

Discharge the Refrigerant R-22 system. (See WP0070).

Using wrench, carefully disconnect the suction and discharge condenser to evaporator

Refrigerant R-22 metal hose line connectors from the coupling halves.

Using wrench, remove the jam nut.
