eration efficiency will result.
4.8 PREVENTATIVE MAINTENANCE
It is recommended that a preventative maintenance sched-
ule be followed to keep the freezer clean and operating
properly. The following steps are suggested as a preven-
tative maintenance guide.
WARNING
Hazardous Voltage and Moving Parts
Never attempt to repair or perform any maintenance
on freezer until all main electrical power to freezer
has been disconnected. Failure to disconnect
electrical power before servicing may result in
serious injury or death.
The United States Department of Agriculture and the Food
and Drug Administration require that lubricants used in
food zones be certified for this use. Use lubricants only in
accordance with the manufacturer's instructions.
A.
Daily Checks
Check for any unusual noise or condition and repair
immediately.
B.
Monthly Checks
1. Check drive belts for wear and tighten belts if
necessary. (Refer to Section 4.5.)
2. Check the condenser for dirt. (Refer to Section
4.6).
4.9 EXTENDED STORAGE
Refer to the following steps for winterizing the freezer or
for storing the freezer over any long period of shutdown
time.
A.
Clean thoroughly with warm detergent all parts that
come in contact with mix. Rinse in clear water and
dry all parts. Do not sanitize.

Do not let cleaning solution stand in freezer barrel
or mix pump during the shutdown period.
B.
Remove, disassemble, and clean the front door,
auger shaft, and mix pump. Leave disassembled
during the shutdown period.

Place plastic auger flights in a plastic bag with a
moist paper towel. This will prevent flights from
becoming brittle if exposed to dry air over an
extended period of time (over 30 days).
