POWER ON the Vortex AC and ROTATE the DISCHARGE Valve (V3) to
achieve a pressure differential of at least 100 PSIG between the LP Gauge
and the HP Gauge. KEEP THE HP BELOW 550 PSIG on the HP Gauge to
ensure that the HP Cutoff Switch will not actuate.
After several minutes of running, the tank will be cold. POWER OFF the Vortex
AC and reconfigure the setup for NORMAL RECOVERY. Repeat as needed.
