SANITIZING – After the machine has been
cleaned and contains no milkstone, the machine
is reassembled. Then a FDA-approved sanitizing
solution is run through the machine to kill bacteria.
The machine is then ready for food preparation.
As a recommended cleaner and sanitizer for your frozen
dessert machine, STERA-SHEEN has proven to be one
of the best daily maintenance products for:
•
CLEANING – Thorough removal of all solids
including butterfat and milk fat.
•
MILKSTONE REMOVAL – Complete removal of
milkstone.
•
SANITIZING – FDA-approved no rinse sanitizer
for food contact surfaces.
ADDITIONAL INFORMATION
THE USE OF DELIMERS
A delimer is a strong acid that has the ability to dissolve
milkstone. This type of chemical may become necessary
once high levels of milkstone have developed. While these
products are very effective for removing HIGH levels of
milkstone, they are not ideal for two reasons:
1.
PRODUCT SAFETY – Strong acids are dangerous
chemicals and handling them requires safety
2.
MACHINE DAMAGE – Strong acids will attack
metal and rubber causing premature wear of
parts. The use of a delimer needs to be closely
monitored to avoid damage to machine surfaces
and parts.
With proper daily use of STERA-SHEEN or its 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 re-
move 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).
Owner's Manual #513613
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 luster of the stainless steel. A mild
alkaline cleaner is recommended. Use a soft cloth
or sponge to apply the cleaner.
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 machine with
a soap solution.
D. QUARTERLY
Air Cooled
The air-cooled condenser is a copper tube and aluminum
fi n type. Condensing is totally dependent upon airfl ow.
A plugged condenser fi lter, condenser, or restrictions in
the louvered panel will restrict airfl ow. This will lower the
capacity of the system and damage the compressor.
The condenser must be kept clean of dirt and grease. The
F112 must have a minimum of 6" (15.2 cm) ventilation on
the right and left sides of the unit for free fl ow of air. The
E112 must have 3" (7.6 cm) ventilation. Make sure the
machine is not pulling over 100° F (37° C) air from other
equipment in the area.
The condenser and condenser fi lter require periodic clean-
ing. To clean, refer to the following procedures.
E112 Air Cooled Condenser Cleaning
A.
Unscrew the knob located on the underside of
the machine towards the front (Fig. 3-10).
B.
Remove the fi lter bracket and remove the fi lter.
C.
Visually inspect the condenser fi lter for dirt.
D.
If the fi lter is dirty, vacuum or brush clean, rinse
with clean water and allow to dry before replacing
on the machine.
