Maintenance Schedule
MINIMUM MAINTENANCE REQUIREMENTS:
Regular maintenance and upkeep is the key to preventing problems with “BE Series” equipment. Keeping
the Process Tank clean is the single-most important preventive maintenance requirement. Avoid the
processing of heavily contaminated used coolant and do not process coolants containing oil, transmission
fluid, or gasoline. When antifreeze/coolant is spilled or splashed, clean it up immediately.
Antifreeze/coolant is poisonous, and will corrode the paint and cabinet of the BE unit.
CAUTION:
Wear proper eye and skin protection when working with this equipment.
CAUTION:
Do not open the fill valve or drain valve during operation or while hot.
Allow a minimum of one-half to two hours for cooling before draining or refilling.
Every cycle:
 DRAIN RESIDUES - Evacuate all residues from the process tank before attempting a waste coolant run.
If less than 3 1/2 gallons of residue drains, perform a cleaning cycle (see “FLUSH” procedure in the
“Weekly” section of the “Maintenance Schedule”). Failure to do so will result in damage to the BE unit.
Weekly or every five (5) waste coolant runs:
 FLUSH - Perform the following flush cycle in order to maintain quality product and to prevent a build-up
of material on the inside of the Process tank. Failure to do so will result in damage to the BE unit. This
is especially important after a residue run.
1. By gravity draining, remove as much residue as possible from the Process Tank.
2. Fill the Process Tank with 5 to 7 gallons of clear water.
3. Depress the On/off Switch to the ON position and allow the unit to run until it automatically shuts off.
This usually takes 2 to 3 hours.
4. Allow the BE unit to cool for at least 1/2 to 2 hours.
5. Place a drain pan (suitable for hot liquid) under the Drain Pipe Assembly and open the Drain Valve.
NOTE: If the drained water is heavy with particulate matter or brown to black in color, the cleaning
process must be repeated until the water begins to drain somewhat clear. Failure to do so can damage
the BE unit.
 CHECK LIQUID LEVELS - Verify that the liquid in the Pump Reservoir is filled to the proper level. If
low, top off with Pump Primer, Recycled Glycol, or clear water until the reservoir overflows out of the
Recycled Glycol hose.
