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 FREEZING CYLINDER 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
Do not overfill the hopper. Mix level must not be higher
than 2 inches (5 cm) from the top of the air inlet tube on
the mix inlet regulator.
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
the mix inlet regulator was installed correctly or that
the freezer is level.
F. Place the FREEZING CYLINDER OFF-ON switch in
the ON position, then press the PUSH TO FREEZE
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. 13).
Figure 14. Sanitizing Agitator Shaft
(SF144 Model Only)
B. Prepare 2 gallons (7.5 liters) of sanitizing solution
following manufacturer’s instructions. Pour into
hopper with mix inlet regulator in place.
C. Place the FREEZING CYLINDER OFF-ON toggle
switch in the ON position and press the CLEAN
switch. Check for leaks.
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. 12).
F. To sanitize SF144 models with the blender, fill a tall
cup with sanitizing solution. Completely immerse the
blender's agitator shaft in the sanitizer solution. Do
not wipe dry (Fig. 14).
