Vortex AC Operating Manual
If the recovery process stalls out because of high head pressure, stop the
Vortex AC, shut off the hose valves and reconfigure the setup as shown in
Figure 3-4 . This can also be done before starting the recovery process, but it
may have marginal long term effect.
NOTE:
This will only work if there is at least 2 kg of liquid in the recovery
tank to develop the necessary pressure differential required.
Figure 3-4 Setup Procedure for Sub-Cooling Method
POWER ON the Vortex AC and ROTATE the DISCHARGE Valve (V3) to
achieve a pressure differential of at least 6.8 bar between the LP Gauge and
the HP Gauge. KEEP THE HP BELOW 37.4 bar 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.
