General Installation Information
DISPENSER INSTALLATION
CAUTION
This equipment is to be installed by trained and
qualified personnel.
ICE MACHINE INSTALLATION
• Refer to the ice machine’s Installation/Use and
Care Guide for the ice machine installation
procedure.
• Order adapter kit K00141, when installing a 22”
Ice Machine with a Dispenser.
• Observe all clearance requirements (see location
of dispenser on page 2-3).
• Install the mounting clip to connect the ice
machine to the dispenser.
• Install legs on the dispenser (to access legs from
their shipping position remove back panel).
MOUNTING
CLIP
MOUNTING CLIP INSTALLATION
1. Open the shipping envelope and remove the
mounting clip (flat plate).
2. Remove the back panel lower mounting screw
from the ice machine. Insert the screw through
the bottom hole on the clip and reinstall the
screw.
3. Remove the screw from the shipping envelope.
Insert it through the top hole on the clip and into
the pre-drilled 5/32” hole on the dispenser back.
NOTE: The ice machine’s ice bridge thickness must
be set for easy dispensing. Set the ice bridge as
directed in the ice machine’s Installation/Use and
Care Guide.
The ice bridge setting must be set thin enough to
allow the ice to break up easily, but thick enough to
insure a clean harvest of the evaporator. An overly
thick bridge will allow ice chunks to fall into the bin,
preventing the sheet of cubes from breaking up for
easy dispensing. This will cause a slower dispensing
rate.
WARNING
Do not attempt to move a dispenser without first
removing the ice machine. The combination can be
unstable and could tip.

Section 2 Installation Instructions
Location of Dispenser
Leveling the Dispenser
The location selected for the dispenser must meet the
following criteria. If any of these criteria are not met,
select another location.
• The location must be indoors.
• The location must be free of airborne and other
contaminants.
• The air temperature must be at least 35°F (1.6°C),
but must not exceed 110°F (43.3°C).
• The location must not be near heat-generating
equipment or in direct sunlight.
• The resting surface must be able to support 600
lb. (272 kg per square meter), which includes the
dispenser, the ice machine and ice.
• The location must allow enough clearance for
water, drain, and electrical connections in the rear
of the dispenser. The location must not obstruct
airflow.
• The dispenser has no minimum air clearance
requirements. When installing an Ice
Machine/Dispenser combination, follow the air
clearance requirements for the Ice Machine being
installed
CAUTION
The dispenser must be protected if it will be
subjected to temperatures below 32°F (0°C).
Failure caused by exposure to freezing
temperatures is not covered by the warranty. See
“Removal from Service/Winterization” on page 4-
4.
After moving the dispenser into the installation
location, it must be leveled for proper operation.
Follow these steps to level the dispenser:
1. Use a level to check the levelness of the ice
machine from front to back and from side to side.

AND
SIDE TO SIDE

2. If the dispenser is not level, adjust the legs on
each corner of the dispenser as necessary.
3. Check the levelness of the dispenser after each
adjustment of the legs.
4. Repeat steps 2 and 3 until the dispenser is level
from front to back and from side to side.

GENERAL
WARNING
All wiring must conform to local, state and national
codes.
WARNING
Never use an extension cord. If an outlet is not
within reach of the dispenser power cord, have a
proper amperage outlet wired closer to the
dispenser.

ELECTRICAL CORD STRAIN RELIEF
To prevent strain at the electrical connection inside
the dispenser, an electrical cord strain relief device
has been installed on the rear panel of the dispenser.
VOLTAGE
The maximum allowable voltage variation is ± 10%
of the rated voltage at dispenser start-up (when the
electrical load is highest).
WARNING
The dispenser must be grounded in accordance with
national and local electrical codes.
FUSE/CIRCUIT BREAKER
A separate fuse/circuit breaker must be provided for
each dispenser.
NOTE: A disconnect means must be provided for
field wiring.
ELECTRICAL RATING
The electrical rating is used to help select the wire
size of the electrical supply. The wire size (or gauge)
also depends on location, materials used, length of
run, etc., so it must be determined by a qualified
electrician.

Section 2 Installation Instructions
Water Service/Drains
WATER CONNECTIONS
Local water conditions may require treatment of the
water to inhibit scale formation, filter sediment, and
remove chlorine odor and taste.
Follow these guidelines to install water inlet lines:
CAUTION
Plumbing must conform to state and local codes.
• Connect to potable water supply only.
• Do not connect to a hot water supply. Be sure all
hot water restrictors installed for other equipment
are working. (Check valves on sink faucets,
dishwashers, etc.)
• If water pressure exceeds the maximum
recommended pressure (90 psig), obtain a water
pressure regulator from your Manitowoc
distributor.
• Install a water shut-off valve at the dispenser.
• Insulate water lines to prevent condensation.
DRAIN CONNECTIONS
Follow these guidelines when installing drain lines to
prevent drain water from backing up into the
dispenser.
CAUTION
Plumbing must conform to state and local codes.
• The dispenser is equipped with a 1/2” F.P.T.
(female pipe thread) fitting at the rear of the
dispenser.
• The dispenser drain must be run separately to
prevent water from other sources from entering
machine.
• Drain lines must be vented to atmosphere.
• Drain lines must have a 1.5 inch (3.75 cm) drop
per 40 inches (1 meter) of run, and must not
create traps.
• The floor drain must be large enough to
accommodate drainage from all drains.
• Insulate the drain line to prevent condensation.

Section 3
Dispenser Operation
Method of Operation (All Models)
When ice is required, the customer or attendant
presses the ice delivery push button switch. This
action activates a relay, which is located in the
control box enclosure. The relay energizes the
dispenser motor.
The dispenser motor is direct-coupled to a right
angle gearbox. This gearbox drives a toothed
positive-displacement belt, the dispensing auger,
and the agitating auger.

Sequence of Operation
QFA-290 PUSHBUTTON OPERATED
ICE DELIVERY
Depressing the ice delivery push button allows
power to flow through the switch to the solid state
relay. The relay energizes and powers the windings
of the dispenser motor. This motor drives a
gearbox, which in turn drives a pulley. A toothed
positive-displacement v-belt is attached to the drive
pulley, a spring loaded tension pulley, and the
agitator and dispenser pulleys. The turning of the
augers causes the ice to ride to the top of the
dispensing auger, where it will open a door and
drop through the ice chute into the glass held
beneath the outlet.
When sufficient ice has been dispensed, the push
button is released and delivery stops.

Depressing the water delivery push button allows

on the water valve. The magnetic action of the
solenoid coil lifts the plunger off its seat on the
diaphragm. Water pressure forces the diaphragm
open allowing water to flow through the tubing and
out the water delivery spout.
When sufficient water has been dispensed into the
glass, the push button is released and delivery stops.

Time Delay Relay
The time delay relay can be adjusted from 1 second
to 100 seconds. It ships from the factory set to 40
seconds. This setting covers the majority of
applications. Settings of less than 40 seconds can
lead to insufficient quantities of ice being dispensed
if the level of ice in the dispenser is low.
