Operating Procedures
Disassembly
MAKE SURE POWER SWITCH IS IN THE
“OFF” POSITION!
Failure to follow this instruction
may result in severe personal injury from hazardous
moving parts.
Step 1
Remove the handscrews, freezer doors, beaters,
scraper blades, and drive shafts from the freezing
cylinders. Take these parts to the sink for cleaning.
Step 2
Remove the front drip tray and the splash shield.
Brush Cleaning
Step 1
Prepare a sink of a cleaning/sanitizing solution with
an active chlorine concentrate of 100 - 200 PPM,
approved for use by your company. Use warm water
and follow the cleaning/sanitizing solution
manufacturer's specifications for dilution.
IMPORTANT
: Follow the label directions. Too
STRONG of a solution can cause parts damage,
while too MILD of a solution will not provide
adequate cleaning. Make sure all brushes provided
with the unit are available for brush cleaning.
Step 2
Remove the seals from the drive shafts.
Step 3
From the freezer doors remove:
S
gaskets
S
front bearings
S
pivot pins
S
adjustable draw handles
S
design caps
S
draw valves
S
all o-rings
Note:
To remove o-rings, use a single service towel
to grasp the o-ring. Apply pressure in an upward
direction until the o-ring pops out of its groove. With
the other hand, push the top of the o-ring forward
and it will roll out of the groove and can be easily
removed. If there is more than one o-ring to be
removed, always remove the rear o-ring first. This
will allow the o-ring to slide over the forward rings
without falling into the open grooves.
Step 4
Remove the o-rings from the air tubes.
Step 5
Return to the unit with a generous amount of
cleaning solution. Brush clean the rear shell
bearings at the back of the freezing cylinders with
the black bristle brush.

film is removed. Take particular care to brush clean
the draw valve cores in the freezer door. Place all
cleaned parts on a clean, dry surface to air dry
overnight.
Step 8
Wipe clean all exterior surfaces of the unit.
