Direct Liquid/Vapor Recovery
This is the typical recovery method Vapor and
liquid lines are routed through your manifold,
into MR45, and out to the recovery cylinder
1. Close valves of recovery cylinder, MR45, and manifold.
2. Set up as shown in the diagram.
3. Open valves of hoses and removal tools.
4. Set MR45 to RECOVER.
5. Open high side of manifold for liquid recovery.
6. To purge air from hoses, briefly unseat hose fitting at cylinder until
vapor is seen. Unseat hose fitting at low side of manifold to purge
low side hose.
7. Fully open vapor valve of recovery cylinder.
8. Press START to begin recovery.
9. Adjust the knob as needed to throttle refrigerant flow if liquid
slugging (knocking) occurs.
10. When liquid recovery is complete, open low side of manifold for
vapor recovery.
11. MR45 stops automatically after vacuum reaches 10”Hg for 10
seconds. For a deeper vacuum, press START to continue recovery.
MR45 stops again after vacuum reaches 20”Hg for 10 seconds. Press
STOP to manually halt recovery at any time.
12. Set knob to SELF PURGE and press START to empty MR45. MR45
stops automatically after vacuum reaches 10”Hg for 10 seconds.
13. Close manifold and cylinder valves after self purge is complete.
14. Remove hoses from MR45, set knob to RECOVER, and cap ports.
