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.

OPEN the DISCHARGE valve (V3) to its fully open position.

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.

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.

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.
