Priming
Step 1
With a pail beneath the door spout, open the draw
valve. P ress the fill switch to allow fresh product 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. Allow the freezing cylinder to fill until the mix
level float switch has satisfied the fill system.

1 of the Priming Procedure.
With a pail beneath the door spout, open the draw
valve. Place the “FILL” switch in the “ON” position.
Press and hold the area labeled “PUSH” on the front
of the post mix valve (prime switch). Release thevalve
after 10 seconds. Allow the product to flow out the
draw valve until full strength product is delivered. This
will force out any remaining sanitizing solution. Close
the draw valve and allow the freezing cylinder to fill.
Step 2
Place the control switch in the “AUTO” position. When
the unit cycles of f, the product will be at serving
viscosity. The viscosity (thickness) of the slush can be
adjusted by turning the viscosity adjustment screw on
the upper right of the front panel. 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.
