CAUTION: ALWAYS WEAR SAFETY GOGGLES, PROTECTIVE CLOTHING, AND GLOVES
WHEN WORKING ON OR WITH THIS UNIT.
CAUTION: NEVER WORK ON OR WITH THIS UNIT WHILE IT IS HOT. ALLOW A MINIMUM
OF TWO HOURS COOL-DOWN TIME.
EVERY CYCLE:
 DRAIN RESIDUES - Evacuate all residues from the process tank before attempting a waste coolant
run. If less than 5 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-55C.
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-55C. For best results, perform a “detergent flush” to help remove oily deposits.
1. By gravity draining, remove as much residue as possible from the Process Tank.
2. Fill the Process Tank with 25 gallons of clear water (follow the filling procedure outlined in the
“Operating the BE-55C” section of this manual). To perform a “detergent flush”, dissolve 4-6 cups
of non-sudsing automatic dishwasher detergent such as Cascade

in the 25 gallons of clear water
before filling the process tank.
3. Depress the Process Switch to the ON position and allow the unit to run for two hours. Then turn
the unit off.
NOTE: Do not allow this cycle to run longer than two hours for the cleaning process. Doing so can
damage the BE-55C.
4. Allow the BE-55C to cool for at least 1/2 hour.
5. Place the Black Drain Hose into a metal waste container. Depress the Drain Assist Switch and
carefully open the Drain Valve. Air will begin to push the residues into your waste container. When
residue no longer is flowing, and only air is coming out of the hose, close the Drain Valve and push
the Drain Assist Switch to the “off” position. Open the manual drain valve and allow any remaining
liquid to flow into a catch pan, and then close the 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 will
damage the BE-55C.
 CHECK LIQUID LEVELS - Verify that the liquid in the Pump Reservoir is filled to the proper level
(refer to “Priming the Circulation Pump” section of this manual). If low, top off with clear water or
processed glycol.
