Vortex Operating Manual
2 Make sure that the hose from the Vortex to the Recovery Tank is
attached to the LIQUID PORT. Open the tank’s LIQUID PORT valve,
keeping the VAPOR port closed.
3 CLOSE the INLET valve (V1).
4 OPEN the DISCHARGE valve (V3) to its fully open position.
5 SET the PURGE/RECOVERY valve (V2) to the RECOVERY position.
6 Open the Manifold Gauge LIQUID valve slowly and verify that no leaks
are present. Extracting as much liquid as possible will speed up the
recovery process.
7 Switch ON the Vortex.
8 MONITOR the inlet pressure (LP, Low Pressure Gauge) and SLOWLY
OPEN the Vortex’s INLET valve (V1). THROTTLE the INLET valve or
the Manifold Gauge’s Liquid and Vapor valves if too much liquid is
entering the machine.
9 When the liquid has been transferred, OPEN the INLET valve (V1) fully
to transfer the remaining VAPOR. Ensure that the Manifold Gauge
valves (liquid and vapor) are also fully opened.
10 Continue to operate until the required VACUUM has been pulled on the
system, as indicated by the LP gauge. Switch OFF the Vortex, CLOSE
the INLET (V1), and wait for 5 minutes. If the Pressure in the system,
as noted on the Manifold Gauge, rises above 0 bar, refrigerant is still
present. If this is the case, REOPEN the INLET (V1), RESTART the
Vortex, and run until the required VACUUM is reached again. Repeat
this process until all the refrigerant is removed resulting in a final
reading, after the 5 minute period, of 0 bar or less.
11 IMMEDIATELY PURGE the Vortex per the procedure as described in
section 3.3 of this Manual.
3.3 PURGING the Vortex
1
Rotate the PURGE/RECOVER valve (V2) to the PURGE position. Rotate
valve V3 to OPEN. See Figure 3-2.
2 Switch the POWER ON and rotate the INLET valve (V1) slowly to the
PURGE. Prevent flooding the compressor with liquid, do not rotate the
V1 valve quickly.
3 Observe the LP Gauge and continue to run the unit until a VACUUM of
at least -0.6 bar is achieved. Switch the POWER OFF and immediately
CLOSE the Recovery Tank’s valve. The INLET valve (V1) should be
returned to the CLOSE position. Finally close V3.
