Welcome––––––––––––––––––––––––––––––––––––––––––––––––––––––––––
Follett equipment enjoys a well-deserved reputation for excellent performance, long-term reliability, and outstanding
after-the-sale support. To ensure that this product delivers that same degree of service, we ask that you take a
moment to review this manual before beginning the installation. Should you have any questions or require technical
help at any point, please call our technical service group at [phone] or [phone].
Before You Begin –––––––––––––––––––––––––––––––––––––––––––––––––––
After uncrating and removing all packing material, inspect the equipment for concealed shipping damage. If damage
is found, immediately notify the shipper and contact Follett Corporation so that we can help in the ling of a claim,
if necessary. If needed, the serial number of your dispenser can be found by removing the drip tray ❶and locating
the serial number label ❷. A QR Code is located on the right hand side of the drip tray ❸. This code allows you to
access manuals, technical bulletins, and on-line training related to the 7 Series dispensers.

Installation ––––––––––––––––––––––––––––––––––––––––––––––––––––––––
CAUTION!
No service or maintenance should be performed until the technician has thoroughly read this service
manual. Except for routine cleaning and sanitizing, only qualied technicians should attempt to service
or maintain this equipment.
1. Measure to verify that the dispenser will t in the desired location.
A clearance of at least 3" (77 mm) is required behind the dispenser
for the electrical and optional drain connection.
2. Ensure that the nished oor inside the cabinet is ush (level) with
the oor outside the cabinet (Fig. 1). If the cabinet oor is lower
than the nished oor, the cabinet oor must be built up (using
appropriate materials) until it is ush with the nished oor. A ush
oor is required for proper operation and maintenance/service of the
dispenser.
3. Rough-in the electrical service, water line, and optional Drip Tray
Drain Kit*.
Note: The dispenser must be installed such that it can be moved
forward at least 4" (10.16 cm) to allow access to the Bin Lid
Cleaning Spout (Fig. 9.6) for dispenser cleaning and sanitizing.
Take this requirement into consideration during rough-in.
§Electrical: 115V, single phase, 15A receptacle required. The dispenser
has an integral 8 ft. (2.4 m) cord and plug.
§Water: supply line (with shut-off valve) connects to the dispenser's 1/4"
MPT inlet.
* The optional Drip Tray Drain Kit (item# 00956375) requires a oor drain
within 15 ft. (4.5 m) of the dispenser. For detailed installation instructions,
please refer to the instructions shipped with the Drip Tray Drain Kit.

4. Install the angle bracket inside the cabinet,18.15" (461mm) from
the toe kick (Fig. 2.1). The bracket prevents the dispenser from
being located/pushed beyond the recommended cabinet space
depth. Do not attach the bracket to the dispenser.

Installation (continued) –––––––––––––––––––––––––––––––––––––––––––––––––
5. Connect water line. Recommended routing (Fig. 3) allows easy access
to water for cleaning and sanitizing procedure.
Fig. 3
6. If installing the optional internal water lter*, please complete the
steps shown in Cleaning and Sanitizing on page 11 before
proceeding. If not, proceed to step 10.
* If your dispenser has the internal water lter option, the water lter must be
installed for the dispenser to operate. Because internal components will need to
be accessed for both procedures, Follett recommends installing the water lter
just prior to initial sanitizing.
7. Lift and remove the top panel, set aside (Fig. 4.1).
8. Remove two screws (Fig. 4.2) and remove left side panel.
9. Install lter as shown. Turn lter clockwise until it is fully seated
(Fig.4.3).
10. Connect power supply.
11. Sanitize the dispenser prior to use (see Cleaning and Sanitizing
on page 11).
