DUKE Soft Serve Freezer Model 927CMT
7 Assembly
CAUTION
To avoid electrical shock or
contact with moving parts,
make sure all switches are
in the “OFF” position and
that the main power supply
is disconnected. Some
freezers have more than
one disconnect switch.
Correct assembly of the freezer is
essential to prevent leakage of the
product and damage to the freezer. You
will need an approved lubricant (such as
Lubri-Film). Make sure all parts of the
assemblies have been cleaned and
sanitized before assembling. Persons
assembling the freezer must first wash
and sanitize their hands and forearms
with an approved sanitizer.
Follow these
instructions for each side of the freezer.
1
.
To assemble the shaft seal, install
the cup seal and O-ring on the
plastic washer. Apply a moderate
amount of approved sanitary lubri-
cant such as Lubri-Film to the O-
ring and the face of the plastic
washer opposite the bell portion of
the seal. Do not allow any lubricant
to come in contact with the bell-
shaped rubber portion of the seal.
See Fig. 7-1.
2.
Install the shaft seal over the rear of
the beater shaft, with the bell-
shaped portion facing the rear. See
Fig. 7-2. Remove any excess
lubricant from the beater shaft.
3.
Place the scraper blades on the
beater shaft, making sure the
blades are installed properly. See
Figure 7-3.
4.
Insert the assembled beater shaft
into the cylinders by placing the rear
blade on the bottom of the cylinder.
This will center the beater and allow
alignment with the drive coupling.
Rotate the beater assembly while
pushing, until the shank has en-
gaged the coupling.
