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.
CAUTION: Understand all class A2L refrigerant warnings and notices if
applicable (pages 4-6).
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. After recovering all liquid, open low side of manifold for vapor.
11. MR45 stops automatically at one of three auto-stop levels:
0 psig (default), 10”Hg, 20”Hg (0 bar, 25 cmHg, 50 cmHg). If
needed, press START to continue recovering until the next level is
reached. Press STOP to manually halt recovery at any time.
12. Set knob to SELF PURGE and press START to empty MR45.
MR45 stops automatically when purging is complete.
13. Close manifold and cylinder valves after self purge is complete.
14. Remove hoses from MR45, set knob to RECOVER, and cap ports.
