1. 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 Plus). 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.
2. Install the cup seal and o-ring on
the washer (see figure 9-6). Apply
a light amount of approved sanitary
lubricant (such as Lubri-Film Plus) 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 into contact with the bell shaped
rubber portion of the seal.
3. Install the shaft seals over the rear of
the beater shafts. If using the three
piece shaft seal the bell-shaped
portion will be facing the rear of the
freezer (see figure 9-2). Remove
excess lubricant from the drive end of
the beater shaft.
4. Place the scraper blades on the
beater shafts, making sure the blades
are installed properly. Proper blade
installation is with flat side against
cylinder wall. (See figure 9-3.)
