With proper daily use of STERA-SHEEN or it’s
equivalent, there is no need for the use of a
DELIMER.
DO NOT USE BLEACH
·
BLEACH HAS ABSOLUTELY NO CLEANING
PROPERTIES.
· BLEACH IS CORROSIVE. It can and will
damage components of the machine causing
premature wear and metal corrosion.
GENERAL PURPOSE CLEANERS
General purpose cleaners do not have the ability to
remove milkstone. Milkstone will become a problem
if not remedied with additional products and
procedures.
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
concentration.
There are two main factors that contribute to falling
chlorine 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 once old solutions become ineffective
B. DAILY
1. The exterior should be kept clean at all times to
preserve the lustre of the stainless steel. A mild
alkaline cleaner is recommended. Use a soft
cloth or sponge to apply the cleaner.
CAUTION
DO NOT USE ACID CLEANERS, STRONG CAUS-
TIC COMPOUNDS OR ABRASIVE MATERIALS TO
CLEAN ANY PART OF THE FREEZER EXTERIOR
OR PLASTIC PARTS.
C. 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.

WARNING
NEVER ATTEMPT TO REPAIR OR PERFORM
MAINTENANCE ON FREEZER UNTIL THE MAIN
ELECTRICAL POWER HAS BEEN DISCON-
NECTED.
The air-cooled condenser is a copper tube and aluminum fin
type. Condensing is totally dependent upon airflow. A
plugged condenser filter, condenser, or restrictions in the
louvered panel will restrict airflow. This will lower the
capacity of the system and damage the compressor.
The condenser must be kept clean of dirt and grease. The
freezer must have a minimum of 3” (7.5 cm) of ventilation on
the right and left sides of the unit for free flow of air (Figure
27). Make sure the freezer is not pulling over 100° F (37° C)
air from other equipment in the area.
The water-cooled condenser is a tube and shell type. The
condenser needs a cool, clean supply of water to properly
cool the freezer, inlet and discharge lines must be 3/8” I.D.
minimum.
