Installation

Before you begin

§ All dispensers must be installed level in both directions to ensure proper operation.

§ All countertop dispensers provide the option of taking utilities out the bottom or back of the dispenser.
See counter cut-out (Fig. 2) for bottom exiting utilities on units with and without drain pans. For installations
where utilities will exit through back of dispenser, refer to back view drawings.

Installing freestanding dispensers

1. Position dispenser in desired location and adjust legs to level in both directions.

2. Connect water supply to 3/8" FPT tting on back of dispenser (Fig. 1).

3. Connect separate drain lines to 3/4" MPT dispenser drain tting, and 3/4" MPT ice machine drain tting

on back of dispenser.

4. Run drain lines to wall or oor drain. If ice machine drain tting is below an intended wall drain, a
condensate pump must be used.

5. If ice machine is a water-cooled unit, connect water-cooled condenser supply line to 3/8" FPT condenser
inlet tting on back of dispenser.

Note: Do not run condenser supply water through ice machine water lter system.

6. Connect condenser drain line to 3/8" FPT condenser outlet tting on back of dispenser.

Important: Do not connect condenser drain line to any other drain lines.

7. Plug dispenser into 15A rated NEMA 5-15 circuit.

8. Remove front cover of base section by removing two screws at bottom corners of cover. Allow cover to

drop approximately 3/8" (5 mm) and pull forward.

9. Turn on water supply and check for leaks.

2. Regardless of whether utilities will exit

through back or bottom of dispenser, drill
four (4) 3/8" holes in counter to anchor
dispenser to counter (Fig. 2).

Note: Follett countertop dispensers can have any

or all utilities run directly through counter or
out rear of dispenser. For dispensers with
any utilities exiting through counter, make
counter cut-out (Fig. 2).

3. For utilities exiting through bottom only:

(a) Make cut out as shown (Fig. 2).

(b) Move drain tting from back of dispenser

and mount where shown (Fig.3).

(c) Cut drain tube to length and attach to barbed

connection.

(d) Move inlet water tting from back of

dispenser and mount where shown (Fig.3).

(e) Cut water tubing to length and re-insert into

water tting.

Note: Utility connections can be accessed through

front of dispenser by removing stainless
steel splash panel, or by removing access
panel (Fig. 4) on back of dispenser.

4. If power is to be supplied through counter cut-out, complete steps 6-9. If power is to be supplied through
rear of dispenser, proceed to step 10.

5. Temporarily remove rear access panel (Fig. 4) from rear of dispenser.

6. Loosen junction box mounting screws. Lift junction box and power cord up until cord and mounting

screws clear notches on rear panel of dispenser. Remove Phillips-head screws from right side of junction
box.

7. Rotate junction box 90 degrees so that screw holes on right side of junction box align with holes on rear
dispenser panel. Secure junction box to dispenser using Phillips-head screws.

8. Place power cord inside dispenser and replace access panel (Fig. 4) to rear of dispenser.

Note: For dispensers to be installed with utilities connected through rear of dispenser, it may be easier to make

preliminary connections before dispenser is set in place.

User information

How the dispenser works

Follett’s 110 series automatic-load ice and water dispensers are equipped with Follett’s 425 lb (193 kg)/day ice
machine. In the continuous icemaking process, water freezes to the inside wall of the evaporator. A rotating
stainless steel auger carries the ice to the top of the evaporator where it is compressed and extruded through an
outlet port. The ice is then pushed through a tube to the storage hopper. When the hopper is full, a bin thermostat
opens and shuts the ice machine off. When the dispense mechanism is activated, a dispense motor is turned on,
causing the wheel to turn. This moves ice to the dispense chute where it drops by gravity into the container held
below the chute.

How SensorSAFE infrared dispensing works

Follett’s SensorSAFE infrared dispensing maximizes sanitation and minimizes the possibility of cross­contamination by eliminating physical contact between the cup or container and dispenser. Sensors in the panel
use reected infrared light to detect the presence of the container and send a signal to a control board which then
activates the appropriate components for ice or water dispensing.

The SensorSAFE infrared dispensing package includes a cleaning switch under the left side of the front cover
which temporarily shuts off dispensing to allow cleaning of the panel and lenses. If the switch is not turned back on
after cleaning, the dispenser automatically resets after two minutes for normal operation.

SensorSAFE infrared dispensing also includes a time limit safety feature which automatically stops ice dispensing
after one minute of continuous dispensing. Dispensing can be resumed by moving the container away from the
dispenser and returning it to the activation zone.

Quiet Night™/Sleep cycle

The board monitors ice dispensing through a line voltage input to P15. If the ice dispense has not been initiated for
more than 5 seconds during the 20 minute time delay, the SLEEP CYCLE LED comes on. The machine will stay
off for 12 hours unless 5 seconds of dispensing is seen. After 12 hours, the SLEEP CYCLE LED goes out and the
ice making will resume if the bin thermostat is closed. The sleep cycle can be deated using the DIP switches on
the ice machine control board.
