The TIF KT-5001 PROMAX 80% Tank Overfill Protection Module, for use with the PROMAX Refrigerant Recovery Machine. This kit provides an easily installed panel that fits in the front of the Vortex and connects to a cable (provided) that plugs into the refrigerant cylinder. This allows for easy, safe recovery of the refrigerant and automatic shut-off of Vortex when the refrigerant cylinder is 80% full. The cable uses a three pin Brad Harrison connector; refrigerant cylinders must be equipped with a refrigerant level tank float sensor.
