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.
