Connect all cables and hoses as described in section 3.1.
NOTE: Make sure all connections are tight, and that the cables and
hoses do not interfere with recovery process. See Figure 1.
Figure 1 Setup procedure for standard refrigerant recovery
2 Make sure the hose connecting Vortex Dual to the recovery tank is
attached to the LIQUID port (LP).
3 OPEN the LP valve on the tank. Keep the VAPOR port CLOSED.
4 Rotate the INLET valve (V1) to CLOSE.
5 Set the PURGE/RECOVER valve (V2) to the RECOVER position.
6 Slowly rotate the LIQUID valve on the MANIFOLD gauge set to OPEN.
Make sure there are no leaks.
7 Turn on Vortex Dual.
8 Monitor the inlet pressure (LP, Low Pressure gauge) and slowly rotate
the INLET valve (V1) to OPEN.
The compressor may emit a knocking sound if Vortex Dual
attempts to recover a significant amount of liquid. To prevent damage
to the compressor, throttle the LIQUID valve on the MANIFOLD gauge
set, or the Vortex Dual INLET valve (V1).
9 Once the liquid has been recovered, transfer the remaining vapor;
rotate the INLET valve (V1) to OPEN. Make sure the LIQUID and VAPOR
valves on the MANIFOLD gauge are OPEN.
