ELECTRICAL CONNECTIONS
• After you remove the panel on the left side of the ma-
chine, the wiring connection box can be found on the
bottom of the frame and is labeled “Connect Power Line
Here” (ref. Fig. 4).
• Feed the power line through the access hole located at
the bottom deck directly below the wiring connection
box.
• Connect the power line to the machine’s power lines
and wiring connection box.
• After connecting, the power line should be fastened to
the wiring connection box with appropriate electrical
hardware.
• In all installations, the machine must be properly
grounded. Because all high voltage components (the
controls are 24 volts) are connected with flexible con-
duit or cord, adequate ground continuity is assured by
running and fastening a ground line to the machine junc-
tion box ground lug (ref. Fig. 4).
BEATER ROTATION
After the electrical connections have been completed
check the rotation of the beater which should be counter-
clockwise when facing the front of the machine.
ELECTRICAL REQUIREMENTS
• The wiring used to operate this freezer must be in
accordance with the National Electrical Code and/or lo-
cal electrical codes, rules and regulations.
• The machine must be properly grounded. We rec-
ommend that a licensed electrician install the power
supply.
POWER SUPPLY
The power supply must be adequate enough to meet
requirements at all times. Voltage fluctuations with the
machine in operation should not exceed plus or minus
5% of the normal or rated voltage.
WIRING
• Adequate wiring must be provided with respect to wire
size or gauge. Unless otherwise required by the local
Electrical Codes, the same gauge wire at the machine
junction box should be used for the direct power line. A
separate circuit breaker with adequate fuse protection
should be employed.
• An unfused disconnected switch or a properly sized
plug and receptacle within 6 feet of the freezer, is rec-
ommended.
CARPIGIANI freezers are equipped with protection for the
beater motor. Should the line voltage drop, or in the un-
likely event a short circuit occurs, the overload protector
will automatically disconnect the starter and the machine
will stop immediately so that no permanent damage can
be caused to the motor.
The compressor is also internally protected. If the Klixon
protector trips due to an overload, the protector must first
cool down for several minutes before the compressor can
be restarted.
