Interconnecting Hoses, Service Hoses, Manifold and Service Coupler Maintenance:
The TRA21 uses brass to brass seal type fittings on the ends of the interconnection hose
assemblies. No hose gasket maintenance is required on the brass to brass type connections.
Periodically inspect the refrigerant hose assemblies, service hoses, manifold and service
coupler inner o-rings for excessive wear. Replace the compenent(s) if required. Periodically
leak check all hose connection points, hose ball valves, manifolds and service couplers.
Since this unit does pull a vacuum in the recovery process, excessive Non-Condensable
Gases (NCG’s) could be sucked into the system and placed in the storage tank.
Liquid filter drier manitenance: The TRA21 is equipped with a 16 cubic inch filter drier with
an integrated moisture indicator. This filter should be checked and replaced periodically.
This filter drier removes any moisture that may be contained in the recovered refrigerant.
Replace the filter drier as follows:
Caution: Always assume the presence of
high refrigerant when removing the filter
drier.
1. Remove filter drier by loosening the brass
flare nuts on each of the fliter drier. Pull
filter drier out of the spring clip holders.
2. Install new filter drier (ARXF2). Make sure
arrow points to the right as in Figure - 1.
3. Tighten brass flare nut into each end of
the new filter drier.
4. Check for leaks.
