Vortex Dual Operating Manual
English
10 Continue to operate until the LP guage indicates the required vacuum has
been obtained.
11 Turn off Vortex Dual and close the INLET valve (V1). Wait five minutes.
If the MANIFOLD gauge indicates pressure has risen above 0 PSIG
(0 bar), refrigerant is still present.
Open the INLET valve (V1) and turn on Vortex Dual.
Run Vortex Dual until the required vacuum is reached again.
Wait five minutes. Repeat this process until all refrigerant
is removed and pressure is 0 PSIG (0 bar), or less.
12 Immediately purge Vortex Dual. Purging is necessary to remove any
residual refrigerant from inside Vortex Dual internal components as well
as the hose from the outlet to the recovery tank. See section 3.3.
3.3 Purging Vortex Dual
1
While Vortex Dual is off, rotate the PURGE/RECOVER valve (V2)
to PURGE. See Figure 2.
2 Turn on Vortex Dual and slowly rotate the INLET valve (V1) to PURGE.
3 Run Vortex Dual and monitor the LP gauge until a vacuum of 20 In/Hg
(0.7 bar) or more is achieved.
4 Turn off Vortex Dual and immediately close the valves on the recovery
tank. Rotate the inlet valve (V1) to CLOSE.
The hose and the discharge port will contain a small amount
of pressurized refrigerant. Exercise care when removing this hose.
