DIRECT VAPOR OR LIQUID RECOVERY

The following is recommended to maximize recovery rates;

A. Use shortest length 3/8” (Inside Diameter) Refrigeration Hose on Suction Side of Recovery Unit.

B. If refrigerant is clean, remove all suction side ﬁlters, screens, etc.

C. Remove all Schrader type valve cores and any valve depressors from hoses and service valves.

D. If Recovery Unit trips OFF on HIGH Pressure, change recovery cylinder.

E. When recovering large amounts of R410A, or if recovering under very high ambient temperatures, we

suggest using the CPS MT69 (Molecular Transformator) which will increase the recovery speed.

1. Connect the unit as shown in Diagram 1. The technician will need to use a refriger-

ant manifold and one spare hose. The manifold should be connected between the unit

being serviced and the TR21 IN port. The spare hose should connect from the TR21

OUT port to an evacuated DOT recovery tank vapor valve. Note: The recovery tank

must be rated for (38 bar) 550 PSI.

2. Open the vapor valve on the DOT recovery tank.

3. Keep the manifold valves closed at this time.

4. Push the main power switch “ON”.

5. Once unit has started, open both HI & LO manifold valves to start the refrigerant

recovery ﬂow.

Note: The TR21 is designed to directly recover large amounts of liquid refrigerant. If

during vapor recovery process the compressor begins to make a slugging or hammering

noise, meter the incoming liquid refrigerant by closing the low side manifold valve until

the noise subsides.

6. The TR21 will run continuously. When a 10” hg. vacuum is observed on the low side

manifold gauge, close both the LO & HI side manifold valves off.

7. If the pressure on the HI side manifold gauge starts to rise, repeat steps 4-7. If HI side

manifold gauge remains in a vacuum, close all tank, manifold and hose valves. Re

move discharge hose from TR21 outlet port. Recovery and Self-Clearing are now

complete.

HIGH SPEED DIRECT LIQUID RECOVERY

The following is recommended to maximize recovery rates;

A. Use the shortest length of 1/4” ID Refrigeration hose on the suction side and discharge side of the unit.

B. If the refrigerant is clean, remove all suction side ﬁlters, screens, etc...

C. Remove all Schrader type valve cores and any valve depressors from the hoses and service valves.

D. Use an evacuated DOT tank.

E. Install a hose between the DOT recovery tank and vapor service valve on the A/C system being

serviced. (See Diagram 2)

F. Use 90lb DOT recovery tank or larger to minimize tank change over.

1. Connect the unit as shown in Diagram 2. The technician will need to use a refriger-

ant manifold (with sight glass) and two spare hoses. The manifold should be con-

nected between the unit being serviced and the TR21 IN port. Connect a refrigerant

hose from the TR21 OUT port to an evacuated DOT recovery tank liquid valve. Con-

nect another refrigerant hose from the DOT tank vapor port to a service port of the

unit being serviced. Note: The recovery tank must be rated for (38 bar) 550 PSI.

2. Open both the vapor and liquid valves on the DOT recovery tank.

3. Keep the manifold valves closed at this time.

4. Push the main power switch “ON”.

5. Once unit has started, open the LO manifold valve on the manifold to start the liquid

refrigerant ﬂow to the TR21. Monitor the liquid refrigerant ﬂow in the manifold sight

glass.

Note: The TR21 is designed to directly recover large amounts of liquid refrigerant. If during

vapor recovery process the compressor begins to make a slugging or hammering noise, meter

the incoming liquid refrigerant by closing the low side manifold valve until the noise subsides.

6. Once liquid refrigerant is no longer present in the manifold sight glass, close the DOT

recovery tank vapor valve. This will transition the unit into direct vapor recovery.

7. Allow the TR21 to run continuously. When a 10” hg. vacuum is observed on the low

side manifold gauge, close both the LO & HI side manifold valves off.

8. If the pressure on the LO side manifold gauge starts to rise, open LO side mani-

fold valve and restart the TR21. lf the LO side manifold gauge remains in a vacuum,

close all tank, manifold and hose valves. Remove discharge hose from TR21 outlet

port. Recovery and Self-Clearing are now complete.

PUSH-PULL LIQUID RECOVERY

The following is recommended to maximize recovery rates;

A. Use shortest length 3/8” (Inside Diameter) Refrigeration Hose on Suction Side of Recovery Unit to Vapor

Port on Tank.

B. Use 3/8” (Inside Diameter) Refrigerant Hoses from system Liquid Service Valve to LIQUID Port on

Recovery Tank.

C. Use an evacuated DOT Tank (90lb or larger, and rated for 550 PSI/38 Bar).

C. If refrigerant is clean, remove all suction side ﬁlters, screens, etc.

D. Remove all Schrader type valve cores and any valve depressors from hoses and service valves.

1. Connect the unit as shown in Diagram 3. The technician will need to use a refriger-

ant manifold with sight glass and two spare hoses. The manifold should be con-

nected between the liquid service port of the system being serviced and the DOT

Recovery tank liquid valve. One spare hose should connect from the TR21 IN port to

the DOT recovery tank vapor valve. The other spare hose should connect from the

TR21 OUT port to the vapor service port on the system being serviced.

Note: The DOT recovery tank must be rated for (38 bar) 550 PSI.

2. Close the manifold LO side valve. Open the manifold HI side valve. Open the DOT

recovery tank’s liquid valve.

3. Push the main power switch “ON”.

4. Open the DOT recovery tank vapor valve. A Push-Pull ﬂow is now enabled.

5. Monitor the scale for DOT recovery tank capacity.

6. Monitor the sight glass in the manifold for the presence of liquid refrigerant. Once

liquid refrigerant is no longer being pushed out of the A/C system being recovered,

close the vapor valve on the DOT recovery tank. Let run for 30 seconds, then turn off

unit.

Note: The Push-Pull recovery does not completely recover all the refrigerant. It will be neces-

sary to proceed to Direct Vapor Recovery Operation (page 6) to complete the recovery process.
