~ Sequence of Operation ~
The BE-55C requires minimal operator involvement. Once the unit is filled with waste coolant and
started, the unit can operate virtually unattended until the process is complete. Following is the normal
sequence of operation for a waste coolant run in the BE-55C.
 FILL - The Fill Hose is inserted into a 55-gallon waste coolant drum. A Fill Switch on the BE-55C
starts a vacuum pump. As a vacuum is formed in the process tank, the Fill Valve is opened to draw
in the waste coolant. When the drum is emptied, the operator switches the Fill Switch off. An
overfill sensor prevents more than 55 gallons from entering the tank.
 WATER PROCESS - The BE-55C Process On/off Switch is depressed, starting the heaters and the
heat-exchanger circulating pump. As the water is heated and vaporizes, it passes through a
condenser and reforms into a distilled water product. This distilled water product gravity drains into
the processed water receiving drum.
 GLYCOL PROCESS - When most of the water has been processed, the temperature inside the
process tank will begin to rise. When this temperature reaches 280
F, a switch closes, energizing
the divert solenoid valve and creating a vacuum. At this point, the upper heaters de-energize and
remain off for the remainder of the cycle. During this portion of the process, the glycol is vaporized
under a vacuum (reducing its boiling point).
 AUTO SHUTDOWN - The BE-55C will automatically terminate the process when the liquid in the
process tank reaches a low level (approximately 5-7 gallons). This low level sensor de-activates
the Process On/off Switch, shutting the unit off.
 DRAIN ASSIST - After the cycle is complete, and the residue in the tank has cooled for two to three
hours, the residues must be drained into a residue collection container. The Drain Assist Switch is
depressed (activating the air supply solenoid) and the Drain Valve is opened until the residues stop
flowing.
 REINHIBIT - After the process is complete, the Processed Glycol can be mixed with Processed
Water or low mineral content tap water to obtain the desired freeze/boil protection and reinhibited
with FTI’s “BE-Series Engine Coolant Treatment” to re-make engine coolant.
 MAINTENANCE - As recommended by this manual, periodic flushing and fluid level checks should
be performed as outlined to insure proper operation and continued quality of recycled product.
