Air Tube (Soft Serve)
The air tube serves two purposes. One end of the 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--r ings 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.
The air orifice is used to meter a certain amount
of air into the freezing cylinder. The air orifice
maintains overrun and allows enough mix to enter
the freezing cylinder after a draw.
Air Tube (Shake)
After priming the machine, install the air tube. Install
the air tube in the position that will allow for the hole
marked “1” to be in the down position. This is the AUTO
position, and will allow mix and air to travel to the
freezing cylinder while product is being dispensed.
Figure 2
During long “No Sale” periods, reverse the position of
the air tube. Position the air tube to allow the hole
marked “2” to be in the down pos ition. This is the
STANDBY position, and will prevent any mix from
entering the freezing cylinder.
Note: Be sure to place the air tubes in the correct
position when returning the freezer to the AUTO
position.
Adjustable Draw Handle
(Soft Serve Only)
These units feature an adjustable draw handle to
provide the best portion control. The draw handle
should be adjusted to provide a flow rate of 5 to 7--1/2
oz. 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.
