Vortex Operating Manual
Check all connections to ensure they are tight before starting the Recovery
Operation.
When recovering refrigerant, it may be necessary to throttle the Manifold
Gauge control valve(s) or the Vortex’s INLET Valve when a significant amount
of liquid is present. This is required if a loud “knocking” sound is heard from
the compressor. While the Compressor in the Vortex is tolerant of liquid, no
compressor will run on 100% liquid without damage for more than a few
minutes. In addition, a liquid “slug” can cause the High Pressure shutoff to
activate, thus adding time to the process. It is thus important to open the valves
slowly and monitor the process carefully. Should the compressor start to
“Knock”, rotate the INLET valve clockwise until the “knocking” stops. This can
also be accomplished by adjusting the Manifold Gauge valves. Exercise care
to ensure that the compressor is not damaged in this way as it will void the
warranty.
It is necessary to use a Refrigerant Scale to ensure that the tank is
not filled to more than 80% of its capacity by weight. When operating in
the NORMAL RECOVERY or PUSH-PULL mode, it is possible to overfill
the tank. Check the tank weight before transporting if you are not sure.
OVERFILLED TANKS CAN RUPTURE EXPLOSIVELY!

Connect all cables and hoses as described in section 3.1 and as shown
in Figure 3-1 below. Ensure that they are tight and routed in such a way
that they will not interfere with the operation.
