Step 10
Remove the two notched drip pans from the left and
right side panels. Take these items to the sink for
cleaning.
Figure 132
Note: If the drip pans are filled with an excessive
amount of mix, it is an indication that the drive shaft
seals, cup seals or o- rings should be replaced or
properly lubricated.
Brush Cleaning
We recommend brush cleaning all the shake parts,
then go back and duplicate these steps (where they
apply) for brush cleaning all the soft serve parts. By
doing so, you will not confuse or interchange these
parts for assembly the next morning. Place the parts
in their proper place in the parts tray.
Step 1
Prepare a sink of cleaning/sanitizing solution with an
active chlorine concentrate of 100 - 200 PPM. USE
W ARM WATER AND FOLLOW THE MANUFACTUR-
ER’S SPECIFICATIONS. Follow label directions, as
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
freezer are available for brush cleaning.
Step 2
Remove the:
S Seal from the drive shaft
S O- rings and guide bearing from the torque
rotor
S Draw valve from the freezer door
S O- rings from the draw valve
S Spinner bearing from the draw valve
S Gasket and front bearing from the freezer
door.
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 3
Remove the o- rings from the pump feed tubes.
Step 4
Thoroughly brush clean all disassembled parts and
parts trays in the cleaning solution, making sure all
lubricant and mix film is removed. Be sure to brush all
surfaces and holes, especially holes in the pump valve
body and the small syrup holes in the shake freezer
door.
Rinse all parts with clean, warm water .
Step 5
Return to the freezer with a small amount of cleaning
solution and the black brush. Brush clean the rear shell
bearings at the back of the freezing cylinders.
