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.
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.
J.
Insert the air bleed valve into the back of the front
door. Install the compression spring onto the air
bleed valve then screw the knob on
fi
nger tight.
K.
Apply a thin layer of sanitary lubricant to the o-rings
on the spigot bodies and install the spigot bodies
through the bottom of the front door.
L.
Fit the front door o-ring 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
fi
nger
tight. Do not overtighten. Proper o-ring seal can
be observed through the transparent front door.
3.8 SANITIZING
Sanitizing must be done after the machine is clean and
just before the machine is
fi
lled with mix. Sanitizing the
night before is not effective. However, you should always
clean the machine and parts after using it.
NOTE
The United States Department of Agriculture and
the Food and Drug Administration require that all
cleaning and sanitizing solutions used with food
processing equipment be certifi ed for this use.
3.7 ASSEMBLING THE 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
lubricant to exposed surfaces of the o-rings.
B.
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 and
install it onto the auger shaft. DO NOT lubricate
the outside of the rear auger seal (Fig. 3-6).
D.
Lubricate the hex drive end of the auger with a
small amount of spline lubricant. A small container
of lubricant is shipped with the machine.
E.
Screw the springs onto the studs in the plastic
fl
ights. The springs must be screwed into the
fl
ights completely to provide proper compression.
F.
Install the two plastic
fl
ights onto the rear of the
auger and insert it part way into the freezing
cylinder.
G.
Install the remaining plastic
fl
ights, push the auger
into the freezing cylinder and rotate slowly until
the auger engages the drive shaft.
