DIRECT VAPOR OR LIQUID RECOVERY

The following is recommended to maximize recovery rates;

A. Use the shortest length of 3/8” ID refrigeration hose on the suction 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. If the unit trips off on High Pressure, change the recovery cylinder.

F. When recovering large amounts of R410a or if recovering under very high ambient temperatures, we

suggest our accessory the MT69 Molecular Transformator.

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 TR19 IN port. The spare hose should connect from the TR19

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 TR19 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 TR19 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 4-6. If HI side

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

discharge hose from TR19 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 refrigerant

manifold (with sight glass) and two spare hoses. The manifold should be connected

between the unit being serviced and the TR19 IN port. Connect a refrigerant hose from the

TR19 OUT port to an evacuated DOT recovery tank liquid valve. Connect 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 TR19. Monitor the liquid refrigerant ﬂow in the manifold sight glass.

Note: The TR19 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 TR19 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 manifold valve

and restart the TR19. lf the LO side manifold gauge remains in a vacuum, close all tank,

manifold and hose valves. Remove discharge hose from TR19 outlet port. Recovery and

Self-Clearing are now complete.

Diagram 2 - High Speed Direct Liquid Recovery

www. .com information@itm.com1.800.561.8187

PUSH-PULL LIQUID RECOVERY

The following is recommended to maximize recovery rates;

A. Use the shortest length of 3/8” ID refrigeration hose on the suction side of the unit to the

vapor port on the tank.

B. Use 3/8” ID refrigerant hoses from the system liquid service valve to the liquid port on the

tank.

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

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

service valves.

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

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

manifold with sight glass and two spare hoses. The manifold should be connected between

the liquid service port of the system being serviced and the DOT Recovery tank liquid valve.

One spare hose should connect from the TR19 IN port to the DOT recovery tank vapor

valve. The other spare hose should connect from the TR19 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 necessary to proceed to Direct Vapor Recovery Operation (page 6) to complete the

recovery process.

shown in Figure 1.

2. Remove suction port-ﬁlter cartridge as shown in Figure 2.

3. Clean cartridge or replace with new cartridge. (CPS #CRXF3)

4. Inspect O-ring. Re-lubricate with compressor oil or equivalent.

5. Place ﬁlter cartridge back into suction port ﬁtting.

6. Hand tighten this assembly back onto TR19.

7. Use 5/8" socket or boxed end wrench to tighten 1/8 of a turn.

Do not over tighten; O-ring damage may occur.
