6.7 SPIGOT SWITCH
The spigot switch is a normally closed, held open switch.
When a spigot is pulled, the spigot switch sends a signal
to the IntelliTec control to start the auger drive and refrigera-
tion system. This signal moves the control to “Serve Mode”,
or if it already is in “Serve Mode”, it resets the cycle count.
After serving product, the IntelliTec continues a freezing
cycle until the product reaches consistency.
SPIGOT SWITCH TEST - ADJUSTMENT
NOTE
Adjustments to the spigot switch should be done
after the product is at consistency in “Serve Mode”
or when the machine is empty.
1. Open the spigot slowly and listen for a click when
the spigot switch closes.
2. The clicking sound should be within the first 1/2” of
the spigot glide movement (Refer to Figure 6-7). If
the switch does not close, an adjustment may be
necessary.
SPIGOT SWITCH TESTING - ELECTRICAL
1. Disconnect the switch from the circuit by unplugging
the connectors.
2. Check resistance readings across the common
(COM) and normally closed (NC) terminals. When
the spigot is closed, the resistance should show
an open. When the spigot is opened, the switch will
close and the resistance should be 0 ohms.
SPIGOT SWITCH ADJUSTMENT
1. Place the Main Power OFF/ON switch and both
Freezing Cylinder OFF/ON switches in the OFF
position.
2. Remove the header panel.
3. Loosen the bolts on the spigot switch.
4. Using a pencil, mark the spigot glide 1/4” from the
spigot housing.
5. Adjust the switch to activate when the plastic glide
reaches the mark.
6. Fully tighten the retaining bolts and remove mark
from spigot glide.
C. GEARBOX INSTALLATION
1. Place the gear box in position from the rear of the
machine. Fasten the bolts through the gear box to
the rear of the barrel.
2. Fasten the gearbox to the mounting bracket using
the two bolts.
3. Mount the pulley on the gear box shaft and align
with the motor pulley, then tighten the allen head
screws.
4. Install the belt.
5. Use a Burroughs Belt Tension Gauge to set the
tension for the drive belt. Set the belt tension to the
following:
E111: 30-40 lbs.
F111: 15-25 lbs.
6. If an adjustment is necessary, loosen the four
motor plate retaining nuts, adjust belt tension then
retighten the four nuts.
6.6 CONDENSER FAN MOTOR (AIR-
COOLED ONLY)
A. FAN MOTOR REPLACEMENT
1. Disconnect machine from electrical supply before
removing any panels for servicing.
2. Remove a side panels.
3. Trace and disconnect the wires on the compressor
contactor.
4. Loosen set screw on fan blade.
5. Remove the bolts from the fan motor mounting
plate and remove the motor.
B. FAN MOTOR INSTALLATION
1. Attach motor to the mounting plate with the three
bolts.
2. Place fan blade on motor shaft and tighten set
screw.
3. Wire the fan motor according to the wiring diagram
located in the header panel.
WARNING
Hazardous voltage
The Main Freezer Power switch must be placed in
the OFF position when disassembling for servic-
ing. The machine must be disconnected from elec-
trical supply before removing any access panel. Fail-
ure to disconnect power before servicing could re-
sult in death or serious injury.
