The TIF KT-5002 PROMAX 80% Tank Overfill Protection Cable, for use with the PROVAX Refrigerant Recovery Machine. This kit provides an easily installed panel that fits in the front of the PROVAX and connects to a cable (provided) that plugs into the refrigerant cylinder. If your unit does not have the internal plug already installed, see KT-5002A. This allows for easy, safe recovery of the refrigerant and automatic shut-off of PROVAX 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.
