OPERATING YOUR RG5410A-E
Procedure for Normal System Recovery
1. Inspect the RG5410A-E thoroughly to insure that it is in good operating condition.
2. Make sure all connections are correct and tight.
3. Open the liquid port of the recovery cylinder (always open valves slowly to check
hoses and connections for leaks).
4. Make sure the Recover/Purge valve is set on Recover.
5. Open the output port of the RG5410A-E.
6. Open the liquid port on the manifold gauge set; opening the liquid port will remove
the liquid from the system first, greatly reducing the recovery time (after the liquid
has been removed, open the manifold vapor port to finish evacuating the system).
7. Connect your RG5410A-E to a 230 V outlet.
a) Switch the main power switch to the ON position. You should hear the
fan running.
b) Press the compressor start switch. This "momentary" switch will start
the compressor (it may be necessary, under certain circumstances, to
press this switch more than once to start the compressor).
8. Slowly open the input port on the RG5410A-E.
a) If the compressor starts to knock, slowly throttle back the input valve
until the knocking stops.
b) If the input valve was throttled back, it should be fully opened once the
liquid has been removed from the system (the manifold vapor port
should also be opened at this time).
9. Run until minimum EPA required vacuum is achieved.
a) Close the manifold vapor and liquid ports.
b) Close the RG5410A-E input port.
c) Shut unit off and proceed with the Self Purge procedure on the next
page.
10. Always purge the RG5410A-E after each use. Failure to purge the remaining
refrigerant from the RG5410A-E could result in the acidic degradation of internal
components, ultimately causing premature failure of the unit.
When pumping liquid, do not allow the RG5410A-E to operate with the input valve
too far open, causing the compressor to knock. Doing so may stall the
compressor.
