PROTECTION FOR THE OPERATOR
A microswitch has been placed on the door of the barrel
with the beater assembly. The switch will immediately
stop the machine when the door is opened. When the
machine stops, the monitor will display "PT." The dis-
play will blink if the machine was running when it was
stopped. The display will be steady (not blinking) if the
machine was already stopped when the door was
opened. After closing the door, the machine remains
stopped and the display resets.
Make sure the machine is stopped before open-
ing the front door.
COMPLETING THE INSTALLATION
The following pages contain important information and
procedures that describe the proper sanitizing, operation,
and maintenance of your CARPIGIANI machine. We feel
certain that your full compliance with these instructions
will ensure the excellent performance and trouble-free
operation of the machine and a profitable business for
years to come.
Failure to closely follow set-up and maintenance
procedures can void your warranty. CARPIGIANI
Corporation will not be responsible for any machine
not properly maintained.
In the event this unit should malfunction, please contact
your CARPIGIANI Distributor or an authorized service
agency.
EXTREME CARE MUST BE TAKEN WHEN RE-
MOVING SIDE, REAR, OR CONTROL BOX PAN-
ELS. ALWAYS TURN THE MACHINE TO THE
OFF POSITION. ALSO TURN OFF THE DISCON-
NECT SWITCH ON THE ELECTRICAL SUPPLY LINE
BEFORE EXPOSING ANY ELECTRICAL CONNECTIONS
AND/OR MOVING PARTS, SUCH AS BELTS, PULLEYS,
FAN BLADES AND BEATER.
MACHINE SAFETY SYSTEM - THERMAL RELAY
The Thermal Relay monitors amperage draw of the beater
motor. When maximum values are reached, the machine
will stop and the monitor will blink "RT" which is the code
that indicates the THERMAL CUT-OUT has been tripped.
Upon automatic resetting of the thermal relay, the display
will stop blinking. Before restarting operation, it is
important to investigate the reason the Thermal Cut-out
tripped. To restart the machine, press the desired button.
PRESSURE SWITCH
The Pressure Switch protects the cooling system
compressor. This switch will stop the compressor in the
event of water flow interruption (water-cooled system) or
air flow obstruction (air-cooled system); resetting is auto-
matic.
If the compressor runs too long, or the machine continu-
ally stops and restarts it may indicate cooling is insuffi-
cient. Call your authorized service technician.
