unplugged when servicing, except when electri-
cal tests are required.
DANGER: Use extreme care during electrical cir-
cuit tests. Live circuits may be exposed.
Section 6: Electrical System
Qualifier Probable Cause Corrective Action
Fuse/Circuit Breaker is
open.
Short Circuit or overload
within unit.
Push Toggle Switches labeled carbonator and
circulator to the off position. Push the Toggle
Switches for Booster Pump, Air Compressor, Agi-
tator and Refrigeration to the off position.
Replace fuse(s) and reset circuit breaker. Push
the Toggle Switches on in the following se-
quence as labeled below, to locate short or
overload within unit, waiting momentarily be-
tween steps. *Agitator *Refrigeration *Carbon-
ator A and/or B *Circulator A and/or B (after
carbonator Motor Cycles off) *Booster Pump
*Air Compressor.
Push the Agitator Toggle Switch in the on
position. If the fuse/circuit breaker opens, the
trouble is in the Agitator Motor Circuit. This
Circuit must be checked for shorts and/or over-
load. If the fuse/circuit breaker does not open
after running about 1 minute, the problem is
not in the Agitator Motor Circuit.
Push the Refrigeration Toggle Switch in the
on position. If the fuses/circuit breaker
opens, the trouble is in the Refrigeration Cir-
cuit. Refer to wiring diagram for possible faulty
components. Push the carbonator Toggle Switch
A to the on position. Draw Carbonated Wa-
ter from the Dispensing valve until Pump cycles.
If the fuse/circuit breaker opens, the trouble
is in the carbonator Circuit. Refer to wiring dia-
gram for possible faulty components.
Push the carbonator Toggle Switch B to the on
position. Follow procedure above for carbon-
ator A. Push the Circulator Toggle Switch A to
the on position. If fuse/circuit breaker
opens, the trouble is in the Circulator Circuit.
Refer to wiring diagram for possible faulty com-
ponents. Push the Circulator Toggle Switch B
to the on position. Follow procedure above
for Circulator A.
Push the Booster Pump Toggle Switch to the
on position (allow unit to cycle). If fuse/cir-
cuit breaker opens, the trouble is in the Booster
Pump Circuit. Refer to wiring diagram for pos-
sible faulty components.
Push the Air Compressor Toggle Switch to the
on position. (Allow unit to cycle). If fuse/
circuit breaker opens, the trouble is in the Air
Compressor Circuit. Refer to wiring diagram for
possible faulty components.
Important Note: Worn out Circuit Breakers or
low voltage are frequently responsible for
shorts and overloads. Contact service agent to
examine possible defective Circuit Breakers or
low voltage.
