Priming
Step 1
With a mix pail beneath the door spout, openthe draw
valve. Press the fill switc h to allow fresh product t o flow
into the freezing cylinder. This will force out any
remaining sanitizing solution. When full strength
product is flowing from the door spout, closethe draw
valve. Allow the freezing cylinder to fill until t he mix
level float switch has satisfied the fill system.

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). Releas e the valve
after 10 seconds. Allow the product to flow out the
draw valve until full strength product is delivered. This

the draw valve and allow the freezing cylinder to fill.
Step 2
Place the control switch in the “AUTO” pos ition. 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 screwon
the upper right of the front panel. Turn the viscosity
adjustment screw clockwise for a t hicker product, or
counterclockwise for a thinner product. After mak ing
an adjustment, allowt herefrigeration system to cycle
2 or 3 times to accurately evaluate the viscosity.

Draining Product From TheFreezing Cylinder
Step 1
Turn the fill switch to the “OFF” position. Place the
control switch in the “WASH” position as far ahead of
cleaning time as possible. This will allow frozen
product to soften for easier draining.

With a sanitized mix pail beneath the door spout, open
the draw valve. When all of the product has been
drained from the mix hopper and freezing cylinder,
close the draw valve. Make sure the control swit ch is
