Syrup Delivery
Shake syrup is stored in the lower front
compartment. Each syrup flavor is delivered to the
dispensing door by a peristaltic pump. Syrup can be
pumped directly from disposable plastic jugs,
stainless steel tanks, or adapted to syrup-in-bag
dispensing. The proper syrup delivery rate is
achieved by calibrating each syrup flavor.
A 24 VDC motor drives each peristaltic pump. In the
AUTO mode, the UVC3 control regulates the motor
speed necessary to dispense syrup at the calibrated
rate. The pump motors run at maximum speed in the
SYRUP PRIME mode.
A relay is used to reverse the rotation of the syrup
pump motor each time the pump operation is
discontinued. The syrup flow must be momentarily
reversed in order to drop the pressure in the line and
close the duckbill syrup valve.
Refer to the Motor Setup section in the Service
Menu, page 31 for motor and reverse time settings.
