20 Models 336, 338 & 339 Operating Procedures
Cleaning
Step 1
Prepare two gallons (7.6 liters) of an approved clean-
ing solution (example: Kay-5R). USE WARM WATER
AND FOLLOW THE MANUFACTURER’S SPECIFI-
CATIONS.
Step 2
Push down the prime plug. Pour the two gallons (7.6
liters) of cleaning solution into the mix hopper.
Step 3
While the solution is flowing into the freezing cylinder,
brush clean the mix hopper, mix level sensing probe,
and the mix inlet hole.
Step 4
Press the “WASH” button. This will cause the cleaning
solution in the freezing cylinder to agitate.
Step 5
Place an empty pail beneath the door spout and raise
the prime plug.
Step 6
When a steady stream of cleaning solution is flowing
from the prime plug opening in the bottom of the
freezer door, lower the draw handle. Draw off all of the
solution.
Step 7
Once the cleaner stops flowing from the door spout,
raise the draw handle and press the “WASH” button,
cancelling the “WASH” mode.
Repeat Steps 1 through 7 for the other side of the
freezer.
Disassembly
Step 1
BE SURE THE POWER SWITCH IS IN THE
“OFF” POSITION. MAKE SURE NO LIGHTS ARE
LIT ON THE CONTROL PANEL.
Step 2
Remove the handscrews, freezer door, beaters,
scraper blades, and drive shafts from the freezing
cylinders. Take these parts to the sink for cleaning.
Step 3
Remove the front drip tray and the splash shield.
Brush Cleaning
Step 1
Prepare a sink with an approved cleaning solution
(example: Kay-5R). USE WARM WATER AND
FOLLOW THE MANUFACTURER’S SPECIFI-
CATIONS. If another approved cleaner 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 seals from the drive shafts.
Step 3
From the freezer door remove:
S gaskets
S front bearings
S pivot pins
S adjustable draw handles
S design caps
S draw valves
S prime plugs
Remove 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.
