3.8 ASSEMBLING MACHINE
To assemble the machine parts, refer to the following steps:
NOTICE
Petrol-Gel sanitary lubricant or equivalent must be
used when lubrication of machine parts is specifi ed.
NOTICE
The United States Department of Agriculture and
the Food and Drug Administration require that lubri-
cants used on food processing equipment be certi-
fi ed for this use. Use lubricants only in accordance
with the manufacturer’s instructions.
A. Assemble all o-rings onto parts dry, without
lubrication. Then apply a thin fi lm of sanitary
lubrication to exposed surfaces of the o-rings.
B. Lubricate the rear seal area on the auger shaft
with a thin layer of sanitary lubricant. Install the
rear seal o-ring. Lubricate the outside of the rear
seal o-ring with sanitary lubricant.
C. Install the stainless steel rear seal adapter into
the rear seal dry (without lubricant). Lubricate the
inside surface of the rear seal adapter, including
the adapter o-ring, and install it onto the auger
shaft. DO NOT lubricate the outside of the rear
auger seal (Fig. 3-5).
D. Lubricate the hex drive end of the auger with a
small amount of spline lubricant. A small container
of it is shipped with the machine.
E. Install the two plastic scraper blades onto the
auger and insert into the freezing cylinder.
F. Rotate the auger until it engages the drive shaft.
G. Assemble the air bleed valve o-ring onto the air
bleed valve. Position the o-ring into the groove
close to the wide part. Apply a thin fi lm of sanitary
lubricant to the o-ring.
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).
CAUTION
Blender motor can NOT be immersed in water or
sanitizer. Wash the motor and mounting bracket
with a mild detergent solution taking care not to
allow water into the motor bearings or seals.
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.
3.6 SANITIZING MACHINE 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.
3.7 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 surface from inside of the
freezing cylinder.
B. Using sanitizing solution and the large barrel
brush provided, sanitize the freezing cylinder by
dipping the brush in the sanitizing solution and
brushing the inside of the freezing cylinder.
C. Remove the rear drip tray by pulling from the side
panel. Clean and replace the drip tray.
