achieve a trouble-free installation. Should you have any questions or require technical help at any time, please call our
technical service group toll free at (800) 523-9361 or (610) 252-7301.
Before you begin
After uncrating and removing all packing material, inspect the equipment for concealed shipping damage.
If damage is found, notify your shipper immediately and contact Follett Corporation for help in filing a claim,
if necessary.
Check your paperwork to determine which model you have. Follett model numbers are designed to provide information
about the type and capacity of Follett equipment. Following is an explanation of model numbers:
50CT400A
Condenser type – A = air-cooled, W = water-cooled
Icemaker capacity and refrigerant – 400 = 400 lbs (181kg)/day, R404A refrigerant
Icemaker location – R = Satellite-fill icemaker, T = integral icemaker in top of cabinet,
B = icemaker in base of freestanding units
Dispenser configuration – C = countertop, H = wall mount, F = freestanding
Approximate storage capacity in lbs
!
Important cautions
• Do not tilt any unit further than 30° off vertical during uncrating or installation
• Dispenser bin area contains mechanical, moving parts. Keep hands and arms clear of this
area at all times. If access to this area is required, power to unit must be disconnected first.
• Follett recommends a Follett QC4-FL4S water filter system (item# 00130299) be installed in
the icemaker inlet water line
• Prior to operation clean and sanitize the dispenser in accordance with instructions found in this
manual
• Ice is slippery. Be sure counters and floors around dispenser are clean, dry and free of ice.

Installation procedure
Before you begin
• All dispensers must be installed level in both directions to ensure proper operation
• Required ventilation and recommended service clearances:
• Countertop and wall mount models with Satellite-fill icemaker (25CR400A/W, 25HR400A/W, 50CR400A/W, 50HR400A/W)
— none. 12" (305mm) at top recommended for service
• Countertop and wall mount models with integral icemaker (25CT400A/W, 25HT400A/W, 50CT400A/W, 50HT400A/W) — 6"
(153mm) at top. 6" (153mm) each side recommended for service
• Freestanding models (25FB400A/W, 50FB400A/W) — 4" (102mm) at rear. 12" (305mm) at top recommended for service
• All countertop dispensers provide the option of taking utilities out the bottom or back of the dispenser.
See counter cut-out on page 9 (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.
• Wall mount models are designed for use above sinks or custom drain pans, and are not normally equipped with
integral drain pans. Front of sink should be a minimum of 23" (584mm) from back wall. Connection of utilities through the
back for wall mount units is the same as shown in drawings for countertop models except that the drain pan is absent.
• SensorSAFE dispensers are shipped with a plastic, protective film on sensor lenses. For proper operation, plastic
film must be removed after installation.
Installing freestanding dispensers
1. Carefully tip dispenser back to expose underside and block up in place.
Do not tilt unit further than 30° off vertical.
!
2. Remove legs from shipping box (taped to drain pan of dispenser) and screw into dispenser bottom, taking care to
seat legs securely against underside of dispenser.
3. Position dispenser in desired location and adjust legs to level in both directions.
4. Connect water supply to 3/8" FPT fitting on back of dispenser (Fig. 1A).
5. Remove 3/4" dispenser drain line plug from back of unit and discard. Connect separate drain lines to 3/4" FPT
dispenser drain fitting (Fig.1B), and 3/4" MPT icemaker drain fitting (Fig. 1C) on back of dispenser.
6. Run drain lines to wall or floor drain. Provide an air break between the drain lines and drain. If icemaker drain fitting
is below an intended wall drain, a condensate pump must be used.
7. If icemaker is a water-cooled unit, connect water-cooled condenser supply line to 3/8" FPT condenser inlet fitting on
back of dispenser (Fig.1D).
Note: Do not run condenser supply water through icemaker water filter system.
8. Connect condenser drain line to 3/8" FPT condenser outlet fitting on back of dispenser (Fig.1E).
Important: Do not connect condenser drain line to any other drain lines.
9. Plug dispenser into 20 amp rated NEMA 5-20 wall socket.
10. Remove front cover of base section by removing two screws at bottom corners of cover. Allow cover to drop
approximately 3/8" (5mm) and pull forward.
11. Turn on water supply and check that water level in float reservoir (when full) is within 1/4" (6mm) of mark on side of
reservoir, and that float moves freely. Check for leaks.

12 Verify that water sensor tabs are immersed in water in reservoir.
13. Remove top front cover by removing two screws at bottom corners of cover. Lift cover slightly and pull forward.
14. If dispenser is equipped with SensorSAFE remove protective plastic coating from dispense sensor labels.
15. Turn on dispenser power and bin signal rocker switches. Check dispenser and icemaker operation.
16. Sanitize icemaker according to instructions in icemaker manual. Discard ice made during sanitizing process.
17. Turn off icemaker bin signal switch.
18. Remove dispenser hopper lid; clean and sanitize dispenser according to instructions beginning on page 16.
19. Turn icemaker bin signal switch on and replace front covers, securing with screws.

Installing countertop dispensers
Dispensers with top mount icemakers cannot be mounted on legs. They must be bolted to counter.
!
Use gloves when lifting icemaker to protect hands from sheet metal edges.
1. Position dispenser in desired location, mark
dispenser outline on counter and remove
dispenser.
2. Drill four 3/8" (5mm) holes in counter (Fig. 2) to
anchor dispenser to counter.
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. If ice transport tube will exit out rear of dispenser,
remove ice transport tube knock-out (Fig. 5G)
from rear of dispenser.
Note: Utility connections can be accessed
through front of dispenser by removing stainless
steel splash panel, or by removing access panel
(Figs. 4, 5) on back of dispenser.
4. If any electric utilities or water line will be
connected through rear of dispenser, remove
utility knock-out (Figs. 4, 5F) from rear of
dispenser and install supplied protective grommet.

5. 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.
6. Temporarily remove rear access panel (Figs. 4 and 5) from rear of dispenser.
7. 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.
8. Rotate junction box 90 degrees so that screw holes on right side of junction box align with holes on rear
dispenser panel. Resecure junction box to dispenser using Phillips head screws.
9. Place power cord inside dispenser and replace access panel (Figs. 4, 5) 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.
10. Apply a thick bead, approximately. 1/4" (6mm) diameter, of NSF listed silicone sealant (Dow-Corning RTV732 or equivalent) 1/4" (6mm) 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
fitting 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. Run water supply line from back of dispenser through utility knock-out (Figs. 4, 5F) or up through counter
cut-out. Connect water supply line to 3/8" FPT fitting on (Fig. 3G) utility flange at bottom of dispenser.
16. Remove 3/4" drain connection plug from either fitting at rear of dispenser (Fig. 3L) or internal fitting
(Fig. 3K), as appropriate. Connect and run a dedicated drain line to wall or floor drain. An air break should be
provided.
17. Proceed with either Satellite-fill or top-mounted icemaker connection instructions, as appropriate.
