Vortex Dual Operating Manual
English
4 Connect the AC power cord to a circuit protected by an appropriately
sized circuit breaker. If an extension cord is absolutely necessary, make
sure it meets the following conditions:
length is not excessive
contains a safety ground wire
wire size 14 AWG or larger for 115 V (ac) or 1.0 mm
2
or larger for
230 V (ac)
Overfilled tanks can rupture and explode. When operating in standard
recovery or push-pull mode, it is possible to overfill the tank. Use a refrigerant
scale to ensure that the tank does not exceed 80% of its capacity, by weight.
Check the tank weight before transporting.
Do not allow Vortex Dual to recover large amounts of liquid too quickly.
NOTE: When a significant amount of liquid is present and enters the
recovery machine too quickly during the refrigerant recovery
process, this is sometimes referred to in the field as a "liquid slug" or
"slugging."
A liquid slug can activate the High Pressure shutoff and prolong the refrigerant
recovery process. If Vortex Dual recovers large amounts of liquid too quickly
(or a liquid slug is present), a loud knocking will sound from the compressor.
Compressor damage caused by recovering a large amount of liquid too
quickly is not covered by the compressor warranty.
Monitor the recovery process carefully. If the compressor begins to knock:
throttle the INLET valve clockwise, or
adjust the MANIFOLD gauge valves until the knocking stops.
