7. Connect the recovery unit to a right outlet. (See the nameplate on the machine) Switch the power switch to
the ON position, to start the compressor.
8. Slowly open the input port on the machine.
1) If the compressor starts to knock, slowly throttle back the input valve until the knocking stops.
2) If the input valve was throttled back, it should be fully opened once the liquid has been removed
from the system (the manifold gauge set vapor port should also be opened at this time).
9. Run until desired vacuum is achieved.
1) Close the manifold gauge sets vapor and liquid ports.
2) Turn off the machine.
3) Close the unit’s input port and proceed with the SELF -PURGE
Note:
If the recovery machine fails to start, rotate the INPUT valve and thMODE valve to purge position. Then rotate the
MODE valve back torecovery position, and open the INPUT valve.
Caution:
Always purge the unit after each
use. Failure to purge the remaining refrigerant from the
unit could result in the acidic degradation of internal
components, ultimately causing premature.
