Priming
Step 1
With a pail beneath the door spout, open the draw
valve. Fill the hopper with FRESH product and allow
it to flow into the freezing cylinder. This will force out
any remaining sanitizing solution. When full strength
product is flowing from the door spout, close the
draw valve.
Step 2
Open the prime plug by turning it counterclockwise
until the air in the freezing cylinder is allowed to
escape. When product rises to the bleed port, close
the prime plug by turning it clockwise until it is snug
against the freezer door.
Step 3
Place the power switch in the “AUTO” position.
When the unit cycles off, the product will be at
serving viscosity. The viscosity (thickness) of the
slush can be adjusted by turning the viscosity
adjustment screw located under the control channel.
Turn the viscosity adjustment screw clockwise for a
thicker product, or counterclockwise for a thinner
product. After making an adjustment, allow the
refrigeration system to cycle 2 or 3 times to
accurately evaluate the viscosity.

Note: To identify the viscosity adjustment screw,
see illustration on page 13.
Step 4
Place the mix hopper cover in position. Periodically,
during the day's operation, check to be sure there is
a sufficient amount of mix in the hopper.
