OPERATION
Direct Vapor or Liquid Recovery
IMPORTANT: Before starting the recover of the refrigerant, a refrigerant identifier should
be used to determine the type and purity of the refrigerant. Failure to properly identify
the refrigerant could potentially expose the user to danger from flammable refrigerants
and health hazards from toxic refrigerants. Cross contamination of refrigerants can also
occur and would require special handling of the refrigerant.
1. Connect the TRA21 to mobile A/C using a manifold set. Use R-134a type manifold
(MAIA6Q) for R-134a system recovery. Use R-1234yf type manifold (MTHFO) for
R-1234yf system recovery. Use commercial type manifold (MBHP6) for commercial
refrigerant recovery.
2. Connect the TRA21 discharge to vapor port of the DOT recovery tank.
3. Connect the Yellow Overfill Sensor Cord to the float in the recovery tank. This cord
is not inclueded on the model TRA21E. For the TRA21E, use scale to monitor tank
weight. All connections should be done as shown in Diagram - 1.
4. Open the vapor valve on the recovery tank.
5. Start unit by pushing main power switch to the “ON” position.
6. Open the HI and LO side manifold valves to start the refrigerant flow.
7. Monitor the LO side manifold gauge. Once the gauge reaches 20˝ HG vacuum, turn
the unit off.
8. Close the vapor valve on the recovery tank.
9. Disconnect the hose from the TRA21 discharge, then a small amount of refrigerant
under pressure will be released.
10. Drain and measure oil from the oil separator. Only new lubricant, as identified by
the system manufacturer, should be replaced in the mobile A/C system. Removed
lubricant from the system and/or the equipment shall be disposed of in accordance
with the applicable federal, state and local procedures and regulations.

OPERATION
Liquid Flush
1. Connect the TRA21 to mobile A/C system LO side service port using the LO side of a
manifold. Do not connect the HI side of the manifold to the mobile A/C system. Keep
HI manifold valve closed throughout this process.
2. Connect the TRA21 discharge to the Vapor Port of the recovery tank. Recovery tank
should have at least 4 times the mobile system refrigerant charge.
3. Connect the Liquid Port of the recovery tank to the HI side service port of the mobile
A/C system. The user will need to provide this hose / coupler assembly.
4. Connect the Yellow Overfill Sensor Cord to the float in the recovery tank. This cord
is not included on the model TRA21E. For the TRA21E, use scale to monitor tank
weight. All connections should be done as shown in Diagram - 2.
5. Open the vapor valve on the recovery tank.
6. Start unit by pushing main power switch to the “ON” position.
7. Open the HI and LO side manifold valves to start the refrigerant flow.
8. Run for 15 minutes to allow liquid refrigerant to flood the mobile A/C system. The
liquid refrigerant will absorb the oil in the A/C system.
9. After 15 minutes, close the liquid valve on the recovery tank.
10. Monitor the LO side manifold gauge. Once the gauge reaches 20˝ HG vacuum, turn
the unit off.
11. Close vapor valve on the recovery tank.
12. Disconnect the hose from the TRA21 discharge, then a small amount of refrigerant
under pressure will be released.

Routine Filter Maintenance
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.
Figure - 1
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.

OPERATION
Trouble Shooting Chart
Problem:
The unit will only pull down to 0 pressure or a slight vacuum.
Solution:
Check all LO side connections for possible leaks. If problem persists,
check vacuum level directly on the compressor inlet port.
Solution:
Check pressure differential at 400 PSIG discharge pressure. At 400 PSIG,
the unit should pull a minimum of a 5” hg. vacuum. If compressor looses
its capability of meeting this differential, the compressor seals may need
to be replaced.
Problem:
HP Red LED lights up, unit starts for a few minutes then shuts off.
Solution:
The high pressure switch has activated. Make sure the discharge valve
and recovery tank valve(s) are open. Check for any other restrictions on
the discharge port of the unit. Correct restriction. Restart the unit.
Problem:
TOS Red LED lights up and the unit shuts off or will not start.
Solution:
1. Check to make sure TOS cord is properly plugged into the recovery
tank float.
2. Check tank weight to verify that the tank is full. Empty or replaced tank.
Problem:
The unit recovers at a very slow pace.
Solution:
Check for restrictions on the suction side connections. Make sure manifold
valves are open. Overtighted hose connections can collapse the rubber
gaskets causing a restriction.
