Model 220 Operating Procedures
Disassembly
MAKE SURE THE CONTROL 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 cross bar screw assembly, the hinges,
pins, the cross bar, the freezer door, the beater
assembly, the scraper blades, and the drive shaft from
the freezing cylinder. Also remove the adjustable shelf.
Take these parts to the sink for further disassembly
and cleaning.
Step 2
Remove the rear drip tray from the side panel.
Note: If the drip tray is filled with an excessive amount
of mix, it is an indication that the drive shaft seal should
be replaced or was improperly lubricated.
Brush Cleaning
Step 1
Prepare a sink with an approved cleaning solution (ex-
ample: Kay- 5R or Stera- SheenR). USE WARM
W ATER AND FOLLOW THE MANUFACTURER’S
SPECIFICATIONS.
If an approved cleaner other than (example: Kay- 5R
or Stera- SheenR) is used, dilute it according to the
label instructions. 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.
Step 2
Remove the seal from the drive shaft.
Step 3
From the freezer door:
Remove the keeper pin on the valve body. Turn the
draw rod handle and pull the draw rod assembly out of
the valve body. Unscrew the valve piston and slide the
bearing holder down off the draw rod. Remove the
o- ring from the valve piston and the bearing holder .
Remove the large o- ring and the front bearing from the
back of the freezer door .
Remove the keeper pin from the cover cap assembly
and remove the cover cap assembly.
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. 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.
Take these parts to the sink for cleaning,
Step 4
Thoroughly brush clean all disassembled parts in the
cleaning solution, making sure all lubricant and mix film
is removed. Place all the cleaned parts on a clean dry
surface to air dry overnight.
Step 5
Return to the freezer with a small amount of cleaning
solution. With the black bristle brush, brush clean the
rear shell bearing at the back of the freezing cylinder .
