BI-MONTHLY:
 HEAT EXCHANGERS (radiators) - Clean the finned-tube surfaces of the heat exchangers by
carefully blowing compressed air through the fins from the outside to the inside. Be careful not to
allow the compressed air to bend the fins. Use a shopvac on the inside to help collect the dust.
ANNUALLY:
 PUMP RESERVOIR - Drain and clean the Pump Reservoir. On the bottom of the Pump Reservoir
is a drain valve and drain hose. Place a five gallon bucket under the reservoir, insert the drain hose
into the bucket, open the drain valve and drain the glycol from the Pump Reservoir. Close the drain
valve. Wipe off any oily residues from the tank surfaces and pump. Re-fill with processed glycol
(water can be substituted, but will result in diluted processed glycol for the next run).
 PROCESS TANK - Clean out the bottom of the Process Tank by removing the Heater Assembly
and scooping out any accumulated residues, see “BE-55C Heater Replacement/Tank Access” on
page 34.
INTERMITTENT USE AND STORAGE:
Take additional precautions if the BE unit is used intermittently (less than once per week) or is placed in
storage (more than one month). Residues left in mechanical components can become “sticky”, liquid
levels can evaporate, and metal parts can corrode. Perform the following maintenance to help prevent
problems with intermittent use and storage:
Intermittent use:
 DRAIN RESIDUES - Do not allow the residues to sit in the Process Tank for any length of time.
Drain according to the “Maintenance Schedule” section of this manual.
 FLUSH - Flush out any residual residues and clean the Distillate Piping by performing a flush
according to the “Maintenance Schedule” section of this manual.
Before restarting with intermittent use:
 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.
