10. Remove the two short drip pans from the
rear panel. Remove the two notched drip
pans from the left and right side panels.
Take them to the sink for cleaning. (See
Figure 98.)

Note: If the drip pans are filled with an
excessive amount of mix, it is an indication
that the drive shaft seal(s), or o-ring(s) 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 p roper place in the parts tray.
1. From the sink proportioner draw McD All
Purpose Super Concentrate (APSC)
(HCS) solution into a sink.
Make sure all brushes provided with the
freezer are available for brush cleaning.
2. 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 the holes in
the pump components and the small
syrup holes in the shake freezer door.
3. Rinse all parts with clean, warm water,
one tray at a time, including the tray.
4. Return to the freezer with a small amount
of cleaning solution. Using the black
brush, clean the rear shell bearings at the
back of the freezing cylinders. (See
Figure 99.)

5. Using the black brush, clean the drive hub
openings in the rear wall of the mix
hoppers. (See Figure 100.)

6. Using the double end brush, brush clean
the syrup line fittings.
7. Prepare a sink with McD Sanitizer (HCS)
solution. Use one packet in 2.5 gallons
(9.5 liters) of water (100 PPM).
8. Repeat step 3 with the sanitizing solution.
9. Sanitize all parts in McD Sanitizer (HCS)
solution for a minimum of 1 minute.
10. Place disasse mbled parts on clean and
sanitized parts trays.
11. Wipe all exterior surfaces of the freezer
with a clean, sanitized towel.
12. Repeat steps 1 through 10 for the soft
serve side of the freezer.
