Priming
1.
With a pail beneath the door spout, raise the draw
arm. Pour 2 gal. (7.6 L) of
fresh
mix into the hopper
and allow it to flow down into the freezing cylinder.
This will force out any remaining sanitizing solution.
When full-strength mix is flowing from the door spout,
lower the draw arm.
2.
Open the prime plug by turning it counterclockwise
until the air in the freezing cylinder is allowed to
escape.
3.
When product starts flowing from the bleed port,
close the prime plug by turning it clockwise until it is
snug against the freezer door.
Important! Failure to remove all sanitizing solution
may result in damage to the freezing cylinder.
4.
Install the air tube in the mix inlet hole.
