D.
Lubricate the hex drive end of the auger with a small
amount of spline lubricant. A small container of
spline lubricant is shipped with the machine.
E.
Screw the springs onto the studs in the plastic
flights. The springs must be screwed into the
flights completely to provide proper compression.
F.
Install the two plastic flights onto the rear of the
auger and insert it part way into the freezing
cylinder.
G.
Install the remaining plastic flights, push the auger
into the freezing cylinder and rotate slowly until the
auger engages the drive shaft.
H.
Apply a thin layer of sanitary lubricant to the inside
and outside of the auger support bushing. Install
the bushing onto the auger support and install the
auger support into the front of the auger. Rotate the
auger support so that one leg of the support points
straight up.
I.
Apply a thin layer of sanitary lubricant to the o-rings
on the spigot body and install the spigot body
through the bottom of the front door.
K.
Apply a thin film of sanitary lubricant to the door
seal o-ring and fit it into the groove on the rear of the
front door.
M.
Place the front door assembly on the mounting
studs and the push front door against the machine
carefully.
N.
Secure the front door to the machine by placing the
knobs on the studs and tightening until finger tight.
Do not overtighten. A proper o-ring seal can be
observed through the transparent front door.
3.6 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.
3.7 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) detergent water and wipe dry.
Do not use highly abrasive materials, as they will mar the
finish. 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 drip tray by pulling from the front panel.
Clean and replace the drip tray.
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 specified.
NOTICE
The United States Department of Agriculture and
the Food and Drug Administration require that lu-
bricants used on food processing equipment be
certified for this use. Use lubricants only in accor-
dance with the manufacturer’s instructions.
A.
Assemble all o-rings onto parts dry, without
lubrication. Then apply a thin film of sanitary
lubricant 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.
Lubricate the inside metal surface of the rear seal
and install it onto the auger shaft. DO NOT lubricate
the outside of the rear auger seal (Fig. 3-6).
