THE USE OF CHLORINE TEST STRIPS
“Test strips” are used to determine concentrations of
active chlorine in sanitizing solutions. To use the strips,
tear off a small portion and submerge it into the sanitizing
solution. Then, compare the color change to the color key
on the side of the test strip dispenser to determine the
approximate chlorine concentration.
The ideal concentration of chlorine needs to be 100 ppm
(as stated by the FDA).
NOTE
Follow the directions on the container for proper con-
centration.
There are two main factors that contribute to falling chlo-
rine concentrations in a sanitizing solution.
1. PRODUCT USE – As the chlorine in the solution
is being used, chlorine concentrations fall.
2. TIME – As time passes, small amounts of chlorine
“evaporate” from the solution. (That is why you
can smell it.)
Sanitizing solutions should not be allowed to fall below 100
ppm chlorine. New solutions should be mixed as soon as
old solutions become ineffective or if you are unsure of the
concentration of chlorine.
3.13 PREVENTATIVE MAINTENANCE
A. DAILY
1. The exterior should be kept clean at all times to
preserve the luster of the stainless steel. A mild
alkaline cleaner is recommended. Use a soft cloth
or sponge to apply the cleaner.
CAUTION
Do not use acidic cleansers, strong caustic com-
pounds or abrasive materials to clean any part of
the freezer exterior or plastic parts. Use of these
types of cleaners will cause equipment damage.
B. WEEKLY
1. Check o-rings and rear seal for excessive wear
and replace if necessary.
2. Remove the drip tray by gently lifting up to
disengage from the support and pulling out. Clean
behind the drip tray and front of the freezer with a
soap solution.
C. MONTHLY
CAUTION
The freezer has an air cooled condenser and must
have the proper air curculation. Maintain at least 3”
of clearance at all louvered panels. Failure to clean
the condenser filter on a regulat basis my result in
serious freezer damage and could void the freezer
warranty.
1. Remove the condenser filter by lifting up and
pulling bottom out and down. Then clean with
warm soapy water. Rinse in clean water and
shake dry, taking care not to damage the filter in
any way.
D. SEMI-ANNUALLY
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.
3.14 EXTENDED STORAGE
Refer to the following steps for storage of the freezer over
any long period of shutdown time:
A. Turn the Power OFF-ON switch to the OFF
position.
B. Disconnect (unplug) from the electrical supply
source.
C. Clean thoroughly with a warm water detergent all
parts that come in contact with the mix. Rinse in
clean water and dry parts. Do not sanitize.
NOTE
Do not let the cleaning solution stand in the hopper
or in the freezer barrel during the shutdown period.
D. Remove, disassemble and clean the front door,
mix inlet regulator and auger parts. Place the
auger flights and the front auger support bushing
in a plastic bag with a moist paper towel to prevent
them from becoming brittle.
E. In a water cooled freezer, disconnect water lines
and drain water. With a flathead screwdriver, hold
the water valve open and use compressed air to
clear the lines of any remaining water.
