2.
To remove the condenser filter, grasp the top and
pull off. Visually inspect for dirt. If the filter is dirty,
shake or brush excess dirt off the filter and wash
in warm, soapy water. Once the filter is clean rinse
thoroughly in warm, clear water and shake dry,
taking care not to damage the filter in any way.
3.
Visually inspect the condenser for dirt by shining
a light through the coil from the back (inside) of the
condenser.
4.
If the condenser is dirty, place a wet towel over the
front (outside) of the condenser.
5.
Using a vacuum, carefully clean the condenser
coil from the inside and outside of the machine. A
stiff bristled brush may help in releasing debris
from between the condenser coils.

SEMI-ANNUALLY
WARNING
High voltage will shock, burn or cause death. Turn
off and lock out main power disconnect before ser-
vicing. Do not operate machine with panels re-
moved.
1.
Check drive belt for proper tension. Push belt in
with one finger, belt should deflect about 3/8".
2.
Lubricate condenser fan motor with S.A.E. 20
weight oil. Three to six drops is required.
CAUTION
Do not over-lubricate; resulting damage could cause
motor failure.

CLEANING AND SANITIZING INFORMATION
Special consideration is required when it comes to food
safety and proper cleaning and sanitizing.
The following information has been compiled by Purdy
Products Company, makers of Stera-Sheen Green Label
Cleaner/Sanitizer and specifically covers issues for clean-
ing and sanitizing frozen dessert machines. This informa-
tion is meant to supplement a comprehensive food safety
program.
SOIL MATERIALS ASSOCIATED WITH FROZEN
DESSERT MACHINES
MILKFAT/BUTTERFAT – As components of ice-cream/
frozen custard mix, these soils will accumulate on the
interior surfaces of the machine and its parts. Fats are
difficult to remove and help attribute to milkstone buildup.
MILKSTONE – Is a white/gray film that forms on equip-
ment and utensils that come in contact with dairy products.
These films will accumulate slowly on surfaces because of
ineffective cleaning, use of hard water, or both. Milkstone
is usually a porous deposit, which will harbor microbial
contaminants and eventually defy sanitizing efforts.
Once milkstone has formed, it is very difficult to remove.
Without using the correct product and procedure, it is
nearly impossible to remove a thick layer of milkstone.
(NOTE: general-purpose cleaners DO NOT remove
milkstone.) This can lead to high bacteria counts and a
food safety dilemma.
IT IS BEST TO CONTROL MILKSTONE ON A DAILY
BASIS BEFORE IT CAN BECOME A SIGNIFICANT FOOD
SAFETY PROBLEM.
In addition to food safety, milkstone can cause premature
wear to machine parts which can add to costs for replace-
ment parts or possibly more expensive repairs if worn
machine parts are not replaced once they have become
excessively worn.
IMPORTANT DIFFERENCES BETWEEN CLEANING
AND SANITIZING
CLEANING vs. SANITIZING
It is important to distinguish between cleaning and sanitiz-
ing. Although these terms may sound synonymous, they
are not. BOTH are required for adequate food safety and
proper machine maintenance.
CLEANING
•
Is the removal of soil materials from a surface.
•
Is a prerequisite for effective sanitizing.
NOTE
An UNCLEAN surface will harbor bacteria that can
defy sanitizing efforts.
Bacteria can develop and resist sanitizing efforts within a
layer of soil material (milkstone). Thorough cleaning pro-
cedures that involve milkstone removal are critical for
operators of frozen dessert machines.
SANITIZING
•
Kills bacteria.
•
Can be effective on clean surfaces only.
NOTE
Using a SANITIZER on an unclean surface will not
guarantee a clean and safe frozen dessert machine.
PROPER DAILY MAINTENANCE: THE ONLY WAY TO
ASSURE FOOD SAFETY AND PRODUCT QUALITY
Proper daily maintenance can involve a wide variety of
products and procedures. Overall, the products and pro-
cedures fall into three separate categories. (Please note
that this is a brief overview intended for informational
purposes only.)
1.
CLEANING – This involves draining mix from the
machine barrel and rinsing the machine with water.
Next, a cleaner is run through the machine. Then,
the machine is disassembled and removable
parts are taken to the sink for cleaning.
2.
MILKSTONE REMOVAL – Since almost all
cleaners do not have the ability to remove
milkstone, the use of a delimer becomes
