Brush-Cleaning
1. Prepare a sink with an approved cleaning solution.
(examples: Kay-5
®
or Stera-Sheen
®
). Use warm
water and follow the manufacturer’s specifications.
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 freezer are
available for brush-cleaning.
2. Return to the freezer with a small amount of cleaning
solution. With a single-service towel, wipe clean the
bearing surface. Brush-clean the rear shell bearings
at the back of the freezing cylinders with the black
bristle brush.
Figure 6-45
3. Remove the rear drip pan (this does not apply to
Model 349).
4. Remove the right side panel and take the white rear
drip pan to the sink for further cleaning.
5. Remove the O-rings from the mix hopper covers.
Remove the O-ring and seal from the driveshaft.
Remove the O-ring and bearing from the baffle
assembly.
6. Remove the draw valve handle pin from the freezer
door.
7. Turn the door upside down and install the draw
handle on the other side of the door. Move the draw
handle to the forward position to allow removal of the
ice buster.
Figure 6-46
8. Remove the ice buster and prepare to remove the
draw handle.
Important! The draw valve is under pressure from
the spring. Apply downward pressure on the draw
valve while removing the draw handle. After the draw
handle is removed, slowly release the pressure on
the draw valve.
9. Remove the draw valve, spring, front bearing, and
gasket. Remove all O-rings.
Note: To remove the O-rings, use a single-service
towel to grasp the O-ring, and 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 until it rolls out of the groove and can
be removed easily.
10. Thoroughly brush-clean all disassembled parts in the
cleaning/sanitizing solution, making sure all lubricant
and syrup is removed. Place all the cleaned parts on
a clean, dry surface to air dry.
11. Repeat step 1 through step 10 for the other side of
the machine.
