will determine the final regulator tube setting.
Adjust for your specific application..
Part VII - Operating the Freezer
A) Stand-By Mode
The machine will automatically stop the keezing process
after achieving the pre-set "consistency" value (number
displayed on the touch pad monitor)..This will indicate
that the product is ready to be served. At this time the
compressor will continue to run and automatically switch
to cooling the mix storage tanks..
During long pauses between servings, press the
"Push to Select" button (#571 2) and select the
"Stand-By" mode of operation. In this mode, you
will significantlyreduce the energy consumption of
the fieezer When placed in this mode the indicator
light L3 will illuminate The mix temperature in both
cylinders and mix stor age tanks are maintained
below 40 degrees F by the electronic temperature
probes Product should not be served while in this
mode as it will be too soft The Monitor (#570) will
only display the temperature in the mix tank while in
this mode.
To serve product, simply place a cup, container, or cone
under the dispensing spout and slowly pull the dispensing
handle down. At this time the beater / auger drive motor
should start and product start coming out. As the product
begins to flow, move the container in a circular fashion
to create a tapering tower if'frozen product.
When the desired portion has been dispensed, close the
handle and pull the container with product straight down
to add a peak.
Dispense the product without exceedingthe freezers
production capacity If you do not exceed this pace and
are carehl to refill the machine with fiesh mix, you can
be sure you will rarely have to pause in selling product,
even during peak times A standard draw rate is % to 1
ounce of product dispensed per second The larger the
portion size, the slower it should be drawn

B) Gravity Fed Machines
C) Pump Fed Machines-Operation
The gravity feed tube consists of'two tubes, one
sliding inside of the other, and a center splash guard.
The inner tube blends the flow of air and mix into
the freezing cylinder..Air enters through the top of
the tube, mix through the bottom.
(Refer to figure 9)
The mix injection pump runs whenever the beater drive
motor is turning To regulate the amount of mix being
injected into the cylinder, pivot the pump suction tube
either to the right (less midmore air) or to the left (more
mix/ less air) (Refer to figure 10)

The outer tube is actually a regulating valve..Lifting
or closing this outer tube changes the hole opening
size on the inner tube which allows more or less mix
to enter the freezing cylinder. Since the air inlet hole
size does not change, the air inlet is constant.
The air intake is through the front two holes of the pump
cover Since the two air inlet holes are fixed, the air
intake is constant To adjust your overrun (yield) you
must regulate the amount of mix being pumped into the
cylinders The mix pump suction tube will change the
orifice size on the tube to allow either more or less mix to
be pumped into the cylinder
You can vary the overrun (yield) by allowing more
or less mix to enter the cylinder by changing You do
this by opening or closing the outer regulator sleeve
setting on the inner feed tube
You will also have to adjust your pump suction tube
during daily operation to either a larger (Left) or smaller
(Right) orifice setting depending on your draw rate and
product viscosity.
The inner splash guard keeps mix from splashing the
underside of the mix tank cover as well as eliminate
clogging of the feed tube.
For heavy draw rates and I or thick viscosity mixes, a
setting of center, one, two, or three positions to the left of
center will be necessary in order to operate the machine
properly.
The draw rate, portion size, and mix viscosity will
determine the final regulating sleeve setting Our
standard setting is 2 to 3 notches up from the
bottom Open the outer tube to increase the mix
amount. Close the outer tube to decrease the mix
amount. Adjust for your specific application
For light draw rates and 1 or thin viscosity mixes, a
setting of center, one, or two positions to the right of
center will be necessary..
The "Normal" operating position for the suction tubes on
this freezer is either one position to the left, center, or one
position to the right..
Part VIII - Periodic Cleaning
Procedures

Part X - Maintenance
Your Coldelite freezer has been designed,
engineered, and manufactured to achieve high performance and long durability The life expectancy of
any machine depends not only on the quality of
engineering, and components used, but also on the
basic maintenance procedures
It is important for you to become familiar with a few
of the basic operating procedures
Only remove or ings with the oring extractor
provided in the machine spare parts kit.
Clean and sanitize the freezer in accordance with
the instructions in this operation manual
Lubricate all orings and seals as instructed.
The wearing or the improper cleaning of the
beater shaft seals will result in product leakage
into the rear of the machine Check the side drip
chutes frequently and replace seals when
necessary
Replace any oring that is leaking or damaged
When all of the spare parts supplied in the spare
parts kit are used, re-order immediately. Do not
wait until the part is urgently needed or causes the
machine to be inoperative without it
NEVER use the Automatic or Stand-By mode in
the cleaning, sanitizing or initial filling of the
freezer. This can damage the freezer and its
components
During the washing, cleaning and sanitizing
procedures, operate the machine in the BEATER
mode as little as possible This will minimize
component wear on the freezer
When removing and installing the freezer parts,
handle these with care DO NOT drop or bang
together as this will damage the parts and affect
the freezersper formance
NEVER use HOT WATER when washing,
cleaning, or sanitizing your freezer or its parts
ALWAYS use luke warm water (80-90F)
!! IMPORTANT !!
If'your machine is Air Cooled, its efficiency depends
on a clean air cooled condenser. The fins of the condenser must be straight and cleaned a minimum of
every two or three months Prior to cleaning the air
condenser, place the machine in the STOP or OFF
mode and disconnect power to the fieezer..
If your machine is Water Cooled, it is important that it is
not stored at a temperature below 32 degrees F Before
storing at a temperature below 32 degrees you must remove all liquids from the freezer and winterize the water
condenser coil This should be performed by an authorized service technician to avoid damage to the freezer
The following is a recommended wearable parts replacement schedule This is for normal operation ofthe freezer
and will vary based on the volume and type of product
served as well as operational and cleaning procedures.
Redacement Schedule
Orings and Seals -Every 6 months or as needed
Beater Scraper Blades - Every 6 months or as needed
Beater End Pusher -Every year or as needed (Maximum
of 3 Seasons of Operation)
Drive Belts - Every 2 years or as needed
Pump Gears - Every 3 years or as needed
Pump Drive Bearings -As needed
Plastic Parts -As need when leaking, scratched, or broken
Rebuild Mix Pumps - Every 5 years or as needed
Check Gearbox Grease Levels -Annually
Electrical Components-When malfunctioning
