Freezing Cylinder
Step 1
With a pail beneath the door spouts, open the draw
valve. Touch the WASH and PUMP symbols

product to spurt out when the draw valve is
opened.
Drain the product from the freezing cylinder and the
mix hopper.
Step 2
When the flow of product stops, touch the WASH
and PUMP symbols
, cancelling the WASH
and PUMP modes. Close the draw valve.

clip and the assembled air/mix pump.
Repeat these steps for the other side of the
machine.
Rinsing
Step 1
Pour two gallons (7.6 liters) of cool, clean water into
the mix hopper. With the white hopper brush, scrub
the mix hopper, the mix level sensing probe, and the
outside of the agitator drive shaft housing. Using the
double ended brush, brush clean the mix inlet hole.
