HEATER BAND REPLACEMENT:
Parts Required:
Quantity Part Number Description
1 J101104 Heater Band
1 J101499 Heater Band Strap, upper
1 J102319 Heater Band Strap, lower with loop
Procedure:
Disconnect electrical power to the BE unit before working with
or replacing the Heater Band.
1. Drain all liquid from the processing tank. Remove the front panel and top panel of the BE unit and set
aside. Be careful—there are four wires and a hose attached to the top panel. Set the top panel on its right
side on top of a crate or other support near the right front corner of the unit. If desired, remove the hose
and wires from the top panel, noting and tagging the proper wire locations for the On/off switch.
2. Remove the side plastic skin surrounding the Process Tank. There is a seam located on the left side,
which should peel apart. This will reveal the tank's insulation.
3. Carefully remove the bottom outside insulation by cutting the plastic holding straps that hold the
insulation. This should reveal the metal tank and the heater band insulation. Carefully remove the heater
band insulation. Be careful—do not damage any electrical wires when removing the insulation.
4. Remove the two electrical wires from the old Heater Band. If the wires are attached at the rear of the
tank, cut the metal straps and loosen the old Heater Band. Carefully turn the old band clockwise to reveal
the Ceramic Terminal Caps and wire terminals. Remove the old band and straps and discard.
5. Thoroughly clean the metal surface of the Process Tank with a wire brush, steel wool, etc. to remove any
baked-on heat transfer grease and/or oxidation. Wipe the tank clean, being sure that the tank's surface is
free from dirt, oily residues, or moisture.
6. At this time, inspect TAS2 and TAS3 for damage due to overheating. Replace any parts or wires that are
suspected to be damaged.
7. Place the new Heater Band onto the tank by sliding it down over the top of the Process Tank.
IMPORTANT: Do not pull the Heater Band open too far. This may damage it internally.
8. Rest the Heater Band on the base of the unit and loosely install the new Heater Band Straps. Be sure that
the strap with the "loop" goes on the bottom of the heater, centering the Heater Band’s terminal within the
"loop" of the strap.
