Purging Hose Configuration – This arrangement of three
4' to 6' hoses with low-loss fittings and a ¼" male flare
Tee fitting can be used to purge a sealed system for both
operating and non-operating compressor situations. No
hand valves are required. (Fig. 4)
Piercing Tool with Access Valve – These access valves
can be installed without the need for brazing and will
not remain on the system when repairs are completed.
Process Tube Adaptor Kit – This kit allows the attachment of
hand valves to various sizes of exposed tubing ends during back
flushing, charging, and/or evacuating a sealed system. (Fig. 6)
Bubble Solution or Electronic Leak Detector – Bubble
solution is the recommended means of checking for high-
side leaks after repairing a pressurized sealed system. (Fig.
7) An electronic leak detector will also detect the presence
of any refrigerant escaping from the sealed system. (Fig. 8)
