2.3FREEZER INSTALLATION
Installationof the freezerinvolvesmoving thefreezer
close to its permanent location, removing all crating,
setting in place, assembling parts, and cleaning.
A. Uncrate the freezer.
B. Accurate leveling is necessary for correct drainage
offreezerbarreland to insure correct overrun. Place
a spirit level on top of the freezer at each corner to
check for level condition. If adjustment is necessary,
levelthefreezerbyturning the bottom part of each
leginorout. Then separate freezer base gasket and
install with the seam to the back and the flat to the
bottom.
C. Aircooled freezers requirecorrectventilation.The
right side of the freezer is the air intake and must
have a 3" (7.5cm) clearance. Air discharges out of the
left side of the unit and must have 3" (7.5cm) clear-
ance. Do not obstruct the intake or discharge
(Fig. 4).
CAUTION
Failuretoprovideadequateventalationwillvoid
Warranty.
D. Place the OFF-ON switch in the OFF position. See
Figure8.
E. Install the drip trays, drain trays, covers and other
miscellaneous parts on the freezer. (Fig. 5)
F. Connect the power cord. The plug is designed for
208 or 230 volt/20 amp duty. Check the nameplate
on your freezer for proper supply. The unit must be
connected to a properly grounded receptacle. The
electrical cord furnished as part of the freezer has a
threepronggroundingtypeplug(Fig.6).Theuseof
an extension cord is not recommended. If one must
be used, use one with a wire size 12 gauge or heavier
with a ground wire. Do not use an adaptor to get
aroundgroundingrequirement.
WARNING
Do not alter or deform electrical plug in any way.
Altering the plug to fit into an outlet of different
configuration may cause fire, risk of electrical
shock, product damage and will void the warranty.

G. Do not operate under unsafe operating condi
tions. Never operate the freezer if unusual or exces
sive noise or vibration occurs.
3.2 OPERATION CONTROLSAND INDICATORS
Before operating the freezer, it is required that the
operator know the function of each operating control.
Refer to Figure 9 for the location of the operating
controls on the freezer.
A. SPIGOT SWITCH
TheSPIGOTswitch will automatically actuate the
auger drive and refrigeration systems when the
spigot is opened to dispense product. When the
spigot is closed, the drive motor and compressor will
remain "on" until the product in the barrel reaches
the proper consistency.

used to start the freezing cycle. During initial freeze
down, the OFF-ON switch is placed in the ON
position.ThenthePUSHTOFREEZEswitchis
pressed until the drive motor and compressor come
"ON".
NOTE
After the auger drive motor starts, there is a 3
second delay before the compressor starts.
Duringthenormaloperation,the red PUSH TO FREEZE
switch light will illuminate after the freezer has been idle
for the preset cycles. Before drawing product, press the
red PUSH TO FREEZE switch if it is illuminated. Wait
until the green light is illuminated before dispensing.

position is used to blend fruit into dairy mix when
makingsmoothies. The LOW speed position is used
during cleaning procedures.
3.3SANITIZING
Sanitizing must be done after the freezer is clean and
just before the hopper is filled with mix. Sanitizing the
night before is not effective. However, youshould
always clean the freezer and parts after using it.
THE UNITED STATES DEPARTMENT OF AGRICUL-
TUREAND THEFOODAND DRUGADMINISTRATION
REQUIRETHATALLCLEANINGANDSANITIZINGSO-
LUTIONS USED WITH FOOD PROCESSING EQUIP-
MENT BE CERTIFIED FOR THIS USE.
When sanitizing the freezer, refer to local sanitary
regulationsforapplicable codes and recommended
sanitizing products and procedures. The frequency of
sanitizing must comply with local health regulations.
Mix sanitizer according to manufacturer’s instructions to
providea100 parts per million strength solution. Mix
sanitizer in quantities of no less than 2 gallons (7.5
liters) of 120°F of water.Allow sanitizer to contact the
surfaces to be sanitized for 5 minutes.Any sanitizer
must be used only in accordance with the
manufacturer’s instructions.
CAUTION
Do not allow sanitizer to remain in contact with
stainlesssteel freezer parts for prolonged
periods. Prolonged contact of sanitizer with freezer
may cause corrosion of stainless steel parts.
In general, sanitizing may be conducted as follows:
A. Push the mix inlet regulator into hopper with air inlet
(long) tube toward the front of the freezer.
(Fig. 10).
Figure 10. Mix Inlet Regulator
B. Prepare 2 gallons (7.5 liters) of sanitizing solution
following manufacturer’s instructions. Pour into
hopper with mix inlet regulator in place (Fig. 11).
Figure 11. Sanitizing Procedure
Figure 12. Clean Control
C. Place the OFF-ON toggle switch in the ON position
while pressing the CLEAN switch. Check for leaks.
(Fig. 12)

Figure 13. Sanitizing Hopper
Figure 14. Spigot Opened and Solution Draining
D. Clean sides of hopper, mix inlet regulator and under-
side of hopper cover using a sanitized soft bristle
brush dipped in the sanitizing solution (Fig. 13).
3.4 FREEZE DOWN AND OPERATION
This section covers the recommended operating proce-
dures to be followed for the safe operation of the
freezer.
A. Sanitize just prior to use.
B. Place the OFF-ON switch in the OFF position.
C. With spigots open, pour approximately 1 gallon (3.8
liters) of mix into the hopper.Allow the mix to flush
out about 8 ounces (0.23 liters) of sanitizing solution
and liquid mix. Close the spigot.
D. Fill hopper with approximately 3 gallons (11.4 liters)
of prechilled (40°F or 4°C) mix.
NOTE
Donotoverfillthehopper.Mixlevelmustnotbehigher
than2inches(5cm)fromthetopoftheairinlettubeon
themixinletregulator.
E. The freezer barrel will automatically fill until it is
about 1/2 full. If freezer barrel does not fill, check for
obstruction in the mix inlet regulator. If freezer barrel
fills over 1/2 full, indicated by low overrun, check for
leaks at the mix inlet regulator O-ring or check if
themix inlet regulator was installed correctly or that
the freezer is level.
F. Place the OFF-ON switch in the ON position, then
pressthePUSHTOFREEZE swtich until the freezer
starts.
NOTE
After the auger drive motor starts, there is a 3
second delay before the compressor starts.
E. After five minutes, place a bucket under the spigot
and open spigot to drain sanitizing solution. When
solution has drained, press the CLEAN snap switch
to stop the auger.Allow the freezer barrel to drain
completely (Fig. 14).
F. Filla tall cup withsanitizingsolution.Completely
immerse the blender's agitator shaft in the sanitizer
solution. Do not wipe dry (Fig. 15).
