B. DISASSEMBLY OF FRONT DOOR
1. Turn the machine off by pressing the Main Freezer
Power Off/On button on the IntelliTec2™ control.
2. Remove the knobs on the front door.
3. Remove the front door by pulling it off the studs.
4. Remove the spigot through the bottom of the front
door.
5. 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.
C. DISASSEMBLY OF 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 machine parts require complete cleaning,
sanitizing 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.
Prepare Stera-Sheen or equivalent cleaner in
2 gallons of 90° to 110°F (32° to 43°C) water
following manufacturers instructions. Place all
parts in the solution and clean with provided
brushes.
B. Rinse all parts with clean 90° to 110°F (32° to
43°C) water.
C. Wash the hopper and freezing cylinder with the
Stera-Sheen solution and brushes provided.
D. Clean the rear seal surfaces from the inside of the
freezing cylinder with the Stera-Sheen Solution.
3.5 SANITIZING MACHINE PARTS
A. Use Stera-Sheen or equivalent sanitizing solution
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) Stera-Sheen solution or equivalent
cleaner and wipe dry.
Do not use highly abrasive materials, as they will mar the
fi nish. Use a soft cloth or sponge to apply the solution.
For best results, wipe with the grain of the steel.
A.
Clean the rear seal surface from inside of the
freezing cylinder.
