Vortex AC Operating Manual
2
Make sure that the hose from the Vortex AC 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 AC.
8
MONITOR the inlet pressure (LP, Low Pressure Gauge) and SLOWLY
OPEN the Vortex AC’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.
If the Tank Full shutoff is not in use, it is necessary to use a
Refrigerant Scale to ensure that the tank is not filled to more than 80% of
its capacity by weight. When operating in the NORMAL RECOVERY or
PUSH-PULL mode without the tank shutoff, it is possible to overfill the
tank. Check the tank weight before transporting if you are not sure.
OVERFILLED TANKS CAN RUPTURE EXPLOSIVELY!
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 AC, CLOSE
the INLET (V1), and wait for 5 minutes. If the Pressure in the system, as
noted on the Manifold Gauge, rises above 0 PSIG, refrigerant is still
present. If this is the case, REOPEN the INLET (V1), RESTART the
Vortex AC, 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 PSIG or less.
11
IMMEDIATELY PURGE the Vortex AC per the procedure as described in
of this Manual.
