Allow the pr oduct to flow over the refractometer. T he
brix reading should register 13 to 14. A reading higher
than this would cause a darker, richer product. The
refrigeration system would have to runlonger tofreeze
this excess syrup. A reading lower than this could
cause a freeze-up in the freezing cylinder because of
the excess water.
Figure 52
To adjust the brix, turn the adjustment screw located
in t he service panel. Clockwise adjustments increase
the amount of syrup to water, and counterclockwise
adjustments decrease the amount of syrup to water.
Adjust the screw in small increments and check the
brix again.
Figure 53
Repeat this step until a correct brix reading is
registered.
Step 5
Once the proper brix has been achieved, close the
sampling valve. Install the front drip tray andthesplash
shield on the front of the freezer.

Step 6
With a pail beneath the door spout, press the BEATER
key. Open the draw valve and drain the freezing
cylinder. Close the draw valve. After three minutes,
press the PRIME key. This will cause the product to
flow to the mix hopper.
Step 7
Hold a large cup under the pressure relief port exit of
the door, until the liquid level (not foam) reaches the
pressure relief port. Lower the prime plug. Press the
OFF key.
Note: A large amount of foam indicates that the prime
plug was raised too high.
Repeat Steps 1 through 7 for the remaining freezing
cylinder(s).
Step 8
To place the freezing cylinder in the AUTO mode,
press the AUTO key. When the unit cycles off, the
product will be at serving viscosity.
