3. Remove the spigots through the bottom of the
front door.
4. Remove all o-rings from parts by fi rst wiping off
the lubrication using a clean towel. Then squeeze
the o-ring upward to form a loop (Fig. 3-4). Roll
the o-ring out of the groove.
CAUTION
Do not use any type of sharp object to remove the
o-rings.
B. REMOVE AUGER
1. Remove the front auger support and bushing.
2. Remove the auger assembly from the machine.
Pull the auger out of the machine barrel slowly.
As the auger is being pulled out, carefully remove
each of the plastic fl ights with springs.
3. Keep the rear of the auger tipped up once it is
clear of the freezing cylinder to prevent the rear
seal assembly from dropping.
4. Wipe the spline lubricant off of the hex end of the
auger with a paper towel. Remove the rear seal
assembly (Fig. 3-5).
5. Unscrew the springs from the auger fl ights.

3.4 CLEANING DISASSEMBLED PARTS

Disassembled parts require complete cleaning, sanitiz-
ing and air drying before assembling. Local and state
health codes will dictate the procedure required. Some
state health codes require a four sink process (pre-wash,
wash, rinse, sanitize, air dry), while others require a three
sink process (without the pre-wash step). The following
procedures are a general guideline only. Consult your
local and state health codes for the procedures required
in your location.
A. Disassemble all parts.
B. Place all front door and auger parts in clean 90° to
110°F (32°C to 43°C) water and wash thoroughly
(four sink procedure only).
C. Place all parts in 90° to 110°F (32°C to 43°C) mild
detergent water and wash thoroughly.
D. Rinse all parts with clean 90° to 110°F (32°C to
43°C) water.
E. Sanitize all machine parts following procedures
outlined below.

3.5 SANITIZING PARTS

A. Use a sanitizer, mixed according to manufacturer's
instructions, to provide a 100 parts per million
strength solution. Mix sanitizer in quantities of
no less than 2 gallons of 90° to 110°F (32°C to
43°C) water. Any sanitizer must be used only in
accordance with the manufacturer's instructions.
B. Place all parts in the sanitizing solution for 5
minutes, then remove and let air dry completely
before assembling in machine.

3.6 CLEANING THE MACHINE

The exterior should be kept clean at all times to preserve
the luster of the stainless steel. A high grade of stainless
steel has been used on the machine to ease cleanup. To
remove spilled or dried mix, wash the exterior with 90° to
110°F (32°C to 43°C) soapy water and wipe dry.
Do not use highly abrasive materials, as they will mar the
fi nish. A mild alkaline cleaner is recommended. Use a soft
cloth or sponge to apply the cleaner. For best results, wipe
with the grain of the steel.
A. Clean the rear seal surfaces on the inside of the
freezing cylinders.
B. Using sanitizing solution and the large barrel
brush provided, sanitize the freezing cylinders by
dipping the brush in the sanitizing solution and
brushing the inside of the freezing cylinders.
C. Remove the drip trays from the front panel. Clean
and replace the drip trays.
