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

3.Connect separate drain lines to 3/4" MPT dispenser drain fitting, and 3/4" MPT ice machine drain fitting on back of dispenser..

4.Run drain lines to wall or floor drain.. If ice machine drain fitting 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 fitting on back of dispenser..

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

6.Connect condenser drain line to 3/8" FPT condenser outlet fitting 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..

Installing countertop dispensers

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 fitting 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 fitting from back of dispenser and mount where shown in Fig. 3..

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

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.
