Air Tube
Theair tube ser ves two purposes. One end of t he tube
has a hole and the other end does not.
Figure 1
1. After priming the machine, lubricate the o- rings
on the air tube (the end with the hole) and
place it into the mix inlet hole. Every time the
draw handle is raised, new mix and air from the
hopper will flow down into the freezing cylinder.
This will keep the freezing cylinder properly
loaded and will maintain overrun.
2. During long “No Sale” periods, remove the air
orifice. Lubricate the o- rings on the air tube
(the end without the hole), and place it into
the mix inlet hole. This will prevent any mix
from entering the freezing cylinder.
IMPORTANT:Make sure the level o f mix in the
hopper is below the mix deliveryhole in the
feed tube. Failure to followthis instruction may
result in lower product quality when normal
operation is resumed.
The air orifice is used to meter a certain amount
of air into the freezing cylinder. The air orifice
maintainsoverrun and allows enough mix toenter
the freezing cylinder after a draw.
Adjustable Draw Handle
These units feature an adjustable draw handle to
provide the best portion control. The draw handle
shouldbe adjus ted to provide a flow rate of 5 to 7- 1/2
oz. (148 to 222 ml) of product per 10 seconds. To
INCREASE the flow rate, turn the screw
COUNTERCLOCKWISE. Turn the screw
CLOCKWISE to DECREASE the flow rate. During
“Sanitizing” and “Rinsing”, the flow rate can be
increased by removing the pivot pin and placing the
restrictive bar on the TOP. When drawing product,
always place the restrictive bar on the bottom.
IMPORTANT!When dispensingproduct, pull only
one draw handleat a time.

Note: Once the draw rate is set, tighten the lock nut
with a wrench.
