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.
§ SensorSAFE dispensers are shipped with a plastic, protective lm on sensor lenses. For proper operation, plastic
lm must be removed after installation.
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.

CAUTION!
Dispensers with top mount ice machines cannot
be mounted on legs. They must be bolted to
counter. Use gloves when lifting ice machine to
protect hands from sheet metal edges.
1. Position dispenser in desired location, mark
dispenser outline on counter and remove
dispenser.
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).
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 in
Fig. 2.
(b) Move drain tting from back of dispenser
and mount where shown in 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 in Fig.3.
(e) Cut water tubing to length and re-insert into
water tting.
4. If ice transport tube will exit out rear of
dispenser, remove ice transport tube knockout from rear of dispenser. Install supplied
grommet for CR models.
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.

RTV-732 or equivalent) 1/4" (6 mm) inside marked outline of dispenser.
11. Carefully position dispenser on counter.
12. Remove four screws securing splash panel to front of dispenser and gently lay splash panel on counter.
(Water line to solenoid valve can be disconnected from water inlet valve by pushing on ring at end of inlet
tting while pulling on tubing.)
13. Secure dispenser to counter with four 3/8" bolts (supplied by others).
14. Smooth excess sealant around outside of dispenser.
15. Proceed with either RIDE or top-mounted ice machine connection instructions, as appropriate.
