Vortex AC Operating Manual
3.0 Setup and Operation
3.1 Getting Started
Only personnel who have been properly trained in the use and
operation of Refrigeration Systems, Refrigerants and Service Equipment
should operate this equipment. Failure to follow proper safety
precautions could result in personal injury or death.
Review the full contents of this Manual before attempting to use
the Vortex AC in actual service.
Install an approved filter on the inlet. Attach the hoses per the diagram below.
The Vortex AC has a female refrigerant flare fitting so that it may accept a filter
with male flare fittings, the hoses then attach to the filter. DO NOT USE AN
ADAPTER FITTING IN PLACE OF A FILTER AS THIS MAY CAUSE
DAMAGE TO THE VALVES AND VOID THE WARRANTY.
Connect the AC Power cord to a circuit that is protected by a 15 amp breaker.
Use an extension cord only when absolutely necessary to perform the service
— be sure it is the minimum length required, that it contains a safety ground
wire and that it contains wires sized 16 AWG or larger.
When recovering refrigerant, it may be necessary to throttle the Manifold
Gauge control valve(s) or the Vortex AC’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 AC 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!
