OPERATING YOUR RG3000-E
Procedure for Normal System Recovery
1 Inspect the RG3000-E thoroughly to insure that it is in good operating condition.
2 Make sure all connections are correct and tight (see diagram on page 8)
3 Open the liquid valve of the recovery cylinder (always open valves slowly to check
hoses and connections for leaks).
4 Open the outlet valve of the RG3000-E.
5 Open the liquid valve on the manifold gauge set; opening the liquid valve will
remove the liquid from the system first, greatly reducing the recovery time (after the
liquid has been removed, open the manifold vapor valve to finish evacuating the
system).
6 Connect your RG3000-E to a 230 V outlet.
7 Switch the main power switch to the ON position. You should hear the
fan and compressor running.
8 Slowly open the inlet valve on the RG3000-E.
a) If the compressor starts to knock, slowly throttle back the inlet valve
until the knocking stops.
b) If the inlet valve was throttled back, it should be fully opened once the
liquid has been removed from the system (the manifold vapor valve
should also be opened at this time).
9 Run the unit until minimum required vacuum is achieved.
a) Close the manifold vapor and liquid valves.
b) Close the RG3000-E inlet valve.
c) Shut unit off and proceed with the Purge procedure on the next page.
10 Always purge the RG3000-E after each use. Failure to purge the remaining
refrigerant from the RG3000-E could result in the acidic degradation of internal
components, ultimately causing premature failure of the unit.
CAUTION
When pumping liquid, do not allow the RG3000-E to operate with the inlet valve
too far open, causing the compressor to knock. Doing so may damage the
compressor.
