1.Inspect the carton and note any damage, regardless if it appears minor. If the carton is damaged,
note on the consignee copy of the freight invoice “exterior carton damage – concealed damage possible”.
2.Cut the banding strap and remove the exterior carton sleeve, internal fillers and plastic bag around
the dispenser. Carefully inspect for damage.
NOTE: IMI Cornelius is not responsible for damaged freight. If damage is found, you must save
all packaging material and contact the freight carrier. Failure to contact the carrier within 48 hours
of receipt may void your claim.
INSTALLATION
1.Typically the dispenser is placed directly on the counter and a food grade silicone sealant is applied
around the base. However, the legs that are included with the dispenser may be used. The following instructions assume the legs will not be used.
2.Depending on the type of counter, it may be necessary to provide access through the counter at the
rear of the dispenser for the drain, power, water and concentrate connections.
3.With the assistance of another person, lift the dispenser using the base and place it on the counter.
NOTE: The dispenser is extremely heavy when operational. Make certain the counter can support
a minimum of 300 lbs. directly below the dispenser.
4.Sanitizing Prior to Initial Use
The beverage system must be cleaned and sanitized after installation is completed to safeguard against
any possible contaminants that may have entered the system during transport or installation. Refer to the
“Cleaning and Sanitizing the System” section of this manual for procedures.
5.Connecting the Water Supply
A. Water Pipe Connections and fixtures directly connected to a potable water supply shall be sized,
installed and maintained according to federal, state and local laws.
B. It is recommended that a 1/2” OD copper supply line with a shut–off valve and water filter be
located within 3–6 feet (.9–1.8 m) of the dispenser.
C. Remove the splash panel. Run the water supply line through the hole in the back of the base
marked “water” and up the front of the unit to the water inlet fitting located behind the splash
panel.
D. Connect the 3.8” ID supply line to water supply with a 3/8” barb fitting.
E. When installing the splash panel, attach the ground wire, at the water bath front, to the splash
NOTE: The dynamic water pressure must be 20 psig (1.3 Bar) minimum to ensure correct valve
flow control and must not exceed 100 psig to avoid valve damage.
6.Filling the Ice Water Bath
A. Remove the top panel and locate the filler hole in the top of the refrigeration deck.
B. Fill the water bath with cool water until it begins to trickle out of the overflow tube and into the drip
tray. Use tap water. Do not use distilled water as it’s purity has very low electrical conductivity.
This can degrade performance of the electronic ice bank control.
C. Reinstall the top panel.
7.Connecting Power Supply & Starting Refrigeration
A. Plug the power cord into a 115VAC 15 Amp grounded receptacle.
B. Place the rocker switch and key switch, both located on the top panel, to the “on” position. Note
that the rocker switch controls power to the dispenser and the key switch controls the pumps and
valves.
C. The Millennium forms an ice bank of approximately 25 lbs. (11.4 kg) in about 5 hours at a room
o
temperature of 75
F (24oC). Once the ice bank has grown to the proper size, the ice bank control
will shut down the refrigeration circuit.
D. The ice bank control operates the compressor and condenser fan motor to control the size of the
ice bank. The control board will not start or re–start the compressor until after the compressor has
been off for at least 3 minutes to all refrigeration system pressure to equalize.
NOTE: It is normal to see water trickle from the overflow as the ice bank forms.
8.Electronic Control Board Function
An integrated circuit board and microprocessor are used to control the electrical functions of the Millennium beverage dispenser. Functional features of the control board include:
• Ice bank control with compressor start-up protection
• LED diagnostics
Inputs to the control board include line power and the ice bank position sensor.Switched outputs from
the circuit board include the compressor, agitator motor, and condenser fan motor (refer to electrical diagram in reference section).
9.Ice Bank Control
The ice bank control operates the compressor and condenser fan motor to control the size of the ice
bank. The control board will not restart the compressor until after the compressor has been off for at least
3 minutes to allow the refrigeration system pressures to equalize.
10. LED Diagnostics
LED diagnostic lights are mounted on the control board to assist in troubleshooting. There is one green
LED and one red LED.
