LOCATION & INSTALLATION
2.1 SAFETY PRECAUTIONS
Do not attempt to operate your Machine until the safety precautions and operating
instructions in this manual are read completely and are thoroughly understood.
Take notice of all warning labels on your Machine. The labels have been put there to
inform and protect persons operating or servicing your equipment. Care must be taken not
to damage or destroy labels during installation and servicing. The labels have been
designed to withstand routine cleaning and handling. Damaged or missing labels should
be promptly replaced with approved labels from Frosty Factory of America Inc.
2.2 INSTALLATION
Placing your Machine in a highly visible area will enhance sales. A suitable station will
be able to support 250 pounds and will have a dedicated electrical outlet.
CAUTION: Do not attempt to share the dedicated electrical outlet with any other
appliance; this will cause the circuit breaker to trip.
1. Uncrate your Machine.
2. The Machine must be placed on a sturdy platform able to hold the weight of the
machine when full of product. Level the machine by turning the adjustable part of the
leg. The machine must be level front to back as well as left to right.
3. Machines equipped with air cooled condensers must have correct ventilation. Air
intake is on the right side when facing the machine and discharge is on the left side.
Air intake requires 8” clearance, exhaust needs 24”. 12” clearance at the top.
NOTE: Locating the unit in direct sunlight, near cooking facilities or any high
heat area will reduce the performance of your machine.
CAUTION: Extended operations under severe heat condition can damage the cooling
system.
NOTE: Establishments that serve beverages from frozen drink machines are
responsible for providing the necessary facilities for cleaning and
sanitizing their food service equipment.
4. Place the three-position switch in the OFF position (center).
5. Connect the power cord. The Machine must be connected to a properly grounded
receptacle. The electrical cord furnished as part of the Machine has a three or four
prong grounding type plug. The use of an extension cord is not recommended. If one
must be used, consult the national and local electrical codes. Do not use an adapter to
get around grounding requirements.

SECTION 3
OPERATION
3.1 MACHINE CONTROLS
Operation of the machine is controlled by two selector switches. Selection of the right
(snowflake) position with the upper (three-position) switch as well as the lower (two-
position) switch will schedule the machine for normal operation. The compressor cycle is
protected by a time delay circuit, which will engage the compressor approximately 1
minute after normal operation is initiated.
The red fill light located above the switches will illuminate when the hopper is near
empty. Fill the hopper as soon as possible in order to keep the freezing system
operational.
Hopper refrigeration is provided by a thermostat controlled system. When both
switches are selected to the right (snowflake symbols), the refrigeration system will
maintain a hopper product temperature between 35 and 40ºF. When the lower switch is
placed in the left (thermometer symbol), hopper cooling continues as before, except that
the compressor and beater motor will cycle on and off only when necessary, to maintain
these temperatures.
Refer to the information below for functions available with various combinations of
switch positions.
Normal Operation –Both switches on
snowflake. Machine will freeze mix to
provide frozen beverage as desired.
Cleaning Operation - The drive
motor will run in the faucet position
to allow a stirring action of the rinse
water while cleaning.
Off - The hand symbol is the
recognized international symbol for
“stop”. In this position,
the machine will not run.
Cooling Operation –Machine will
automatically come on whenever
necessary to keep hopper product
cooled to 5ºC/40ºF used primarily for
overnight storage of product remaining
in the machine.

3.2 THE PRODUCT YOU SERVE
The Machine will produce a fine grain, semi-frozen slush when the proper mix is used.
When measured with a refractometer, the proper mix will measure 13 to 18 “brix”. Too
little sugar in the mix will cause larger ice crystals to form. Too much sugar will
lengthen the freeze time.
CAUTION: Any attempt to freeze water only will cause severe damage to your
machine.
NOTE: Do not add sugar directly into the machine, as some of it will settle and
result in an improper mix.
FRUIT JUICES with at least 32 grams of sugar per 8-oz. serving will freeze well in
the Machine. They will remain stable during the freezing process while retaining their
natural color and flavor.
NEUTRAL BASES are used to produce a neutral frozen cocktail base. A wide variety
of different drinks can be created from one neutral base by the addition of various flavors.
Most brands of neutral bases specify a mixture of four parts water to one part neutral
base. However, before use in the Machine, be sure the “brix” level is 13 to 18.
The amount of ALCOHOL in the recipe will affect the freezing process. As a rule of
thumb, for the mix to freeze properly, the recipe should contain no more than 25 percent
alcohol.
Suggestion for optimum production and sales:
1) Use the finest ingredients available.
2) Test the product before serving it.
3) Keep the machine clean - ALWAYS!
3.3 PRODUCT CONSISTENCY
An exclusive torque sensing mechanism
developed by Frosty Factory of America
will produce consistent texture and
thickness of your frozen beverages. The
adjustment screw (accessible through the
left side panel as you face the machine
front) is pre-set at the factory. Various mix
consistencies can be achieved by turning
the screw clockwise (thicker drink) or
counter clockwise (thinner drink). Turn
the screw one full turn then allow enough
time to lapse (about three minutes) for the
compressor to complete a cycle before
sampling. Continue this process until
desired result is obtained.
TCC screw is visible through opening at rear of
cabinet (as shown). Use a straight slot screwdriver
to adjust. Clockwise thickens beverage,
counterclockwise makes beverage thinner.

3.4 START U
NOTICE: Before start-up, be sure the machine has been sanitized in accordance with
procedures set forth in the cleaning section of this manual.
Pour the mix into the hopper and allow it to drain into the cylinder.
NOTICE: Always add mix as soon as the orange, level indicator light, above the
switches, comes on to prevent air from entering the cylinder.
CAUTION: Allowing air into the cylinder will cause a rocking motion of the machine.
If the mix is not yet frozen the air can escape by turning the machine off for
20-30 seconds.
WARNING:
3.5 FREEZE TIMES
The freeze time on the Model 237A is approximately 20 minutes when ideal
conditions are met. Such as, starting mix temperature of 40 degrees and room
temperature at 80 degrees. The time will increase with warm mix or if the machine is
not properly ventilated or is operated in a hot environment. Recipes with high alcohol
or high sugar content will naturally take a little longer.
Never under any circumstances,
place your finger or any other object
into the hopper or feed hole while the
machine is in operation. Serious
personal injury may occur.
When the cylinder is full and the hopper is filled to one inch from the top, the machine is
ready to run. Turn on by selecting the “right” (snowflake) position of both switches on
the front panel.
Fill the
Hopper
to about
1 inch
from the
top
Do not run the
machine when
the freezing
cylinder is not
completely full!
