Correct installation of RIDE™model ice machine(s) is critical to proper performance of the ice machine. Refer to
installation manual packed with ice machine for important details on ice transport tube run, ventilation
requirements and other installation requirements. Failure to comply with instructions may void warranty.
To start and operate dispenser
1. Follow detailed cleaning instructions in service manual before operating dispenser.
2. For manual load units, remove front drain pan or rear lid and ll storage area with approved ice.
Note: Follett manual load dispensers can accommodate most cube/cubelet ices up to 1" square, or Follett
compressed nugget ice. Crushed, ake, bagged, nugget or congealed ice cannot be used. Use of these
ices can jam dispenser and void warranty. Separate any “waffle-like” sections of cubes before adding to
dispenser. For ice compatibility questions, please call Follett customer service at [phone] or

Operation
How the dispenser works
Follett’s dispensers are available in automatic load
congurations, fed from one or two Follett RIDE
model ice machines or manual load congurations
(using ice from another source).
In all models, ice is stored below the counter in the
dispenser storage area. When the dispense lever
or button is pushed, the dispense motors are
activated. This causes the wheel assembly in the
storage area to turn, moving ice to the vertical
auger assembly, which carries ice up to the
dispense chute where it drops by gravity into the
container.
In automatic load units, ice is manufactured in
either one or two Follett RIDE model ice machines.
These ice machines may be located up to 20 ft (6
m) away from the dispenser. Extruded ice is
transported through a tube and pushed to the
storage compartment of the dispenser. When the
bin is lled, a bin thermostat shuts the ice machine
off to avoid overlling of the bin. The ice machine
will restart after 20 minutes if the bin is calling for
ice.
Cleaning
Using solutions below, clean and sanitize storage area and beverage lines before starting unit and on a routine
basis as noted below.
Note: Always disconnect power before cleaning dispenser.
Do not run plastic parts through a dishwasher.
Solution A: Combine 1 oz (30 ml) bleach with 2 gal (8 L) hot water.
Solution B: Combine 1/4 oz (7 ml) bleach with 2 gal (8 L) hot water.
Note: Cleaning solutions temperature must be at 75 – 125 F (24 to 52 C)
Recommended cleaning prior to start up
