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. Re-install 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 14 lbs. (6.4 kg) in about 5 hours at a room temperature

of 75°F (24°C). 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 restart the compressor until after the compressor has been off for at least 3 minutes to allow 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. Switche

d 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

trol board will not restart the compressor until after the compressor has been off for at least 3 minutes to allow

con 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

ne red LED.

• Green ON = line voltage is within acceptable range

11. Connecting the Drain

A. Remove the drip tray from the dispenser and drill out the stem with a 7/16” (11 mm) drill bit.

B. Route one end of the 5/8” (15.8 mm) ID hose through the hole in the back of the dispenser marked “drain”

and up to the drip tray fitting located on the dispenser under the drip tray.

C. Attach the hose to the drip tray fitting on the dispenser.

D. Connect the other end of the hose to a suitable drain source, ensuring compliance with all federal, state

and local codes.

E. Slide the drip tray back into place.

12. Purging Air from the Water Coil

A. Prior to initial use, purge all air from the valves by pushing the dispensing switch repeatedly. Continue until

a steady flow of water is observed.

B. Repeat for the remaining valves.

NOTE: Splashing may occur during the purge cycle.

13. Programming the Portion Control

A. If the dispenser comes equipped with the optional Portion Control feature, they have been

pre-programmed from the factory to pour 7, 12 and 16–ounce drinks. The extra large (pitcher icon) size has also been pre-programmed to pour 16 ounces. To change the pour sizes, please follow the instructions below:

1. Simultaneously press and hold the “small” and “extra large” push button switches on the Portion Control Module until the “refill” light starts blinking. Release the switches. The blinking refill light indicates the programming mode is active.

2. Place the cup under the dispense nozzle and push the selected size button (small, medium, large or extra large). Hold the button until the cup fills to the desired portion, then release the button. Repeat the above procedure for the remaining sizes.

3. After programming all the drink sizes, press and release the “cancel/pour” switch to return the Portion Control to the operational mode. The blinking refill light will go out.

B. If in future it is decided to change the portion size of the drinks, the individual sizes can be adjusted follow-

ing the above procedure. It is not necessary to reprogram every size. Additionally, the Portion Control has full memory retention in case of a power failure.

C. To pour a drink without using a pre–programmed Portion Control size, simply push and hold the “cancel/

pour” button and release when the cup is full.

14. Connecting the Concentrate & Priming the Pumps

A. Connect the 3/8” barb fittings to the BIB supply line.

NOTE: DO NOT cut any of the lines coming from the rear of the dispenser. The excess slack is needed to be able to slide the pump platform out of the front of the base for maintenance access.

B. Route the concentrate supply lines to the BIB location and attach the supplied plastic BIB connector to the

end of each line with the clamps provided.

C. Turn off the water supply and connect the concentrate lines to their respective BIB.

E. Turn on the water supply.

Page 10

Millennium II 4000 Installation Manual

15. Apply Sealant to Base and Countertop

If the legs supplied with the dispenser are not used to raise the dispenser off the counter, the entire perimeter of the base must be sealed at the countertop with silicone (or other food grade approved sealant) in order to comply with NSF standards.

16. Brixing Concentrate

The following procedures describe how to adjust the water to concentrate ratio (brix) according to taste. Contact the concentrate supplier for recommended brix ratios.

Unit comes with a water coil for dispensing water only. The push button valve to actuate is located on the left side of the valve panel. Water solenoid assembly to control flow rate is mounted on the syrup pump platform. The flow rate can be adjusted by turning adjusting screw on the regulator. Turning screw clockwise increases flow rate, turning counter-clockwise reduces flow rate.

A. Remove the flavor strips above the dispense valves.

B. Sample the finished drink. Increase or decrease the water ratio by inserting a flat blade screwdriver into the

slot behind the flavor label and turning the water flow control screw clockwise (more water) or counter– clockwise (less water) until the desired water to concentrate ratio is achieved. Repeat the procedure on the remaining valves.

C. Replace the flavor strips.

NOTE: If the flow control does not respond, there may be debris caught between the internal ceramic spool and sleeve. Try dislodging the debris by pressing the dispense switch several times or by turning the flow control adjustment screw all the way in and out several times.

1. Cleaning and Sanitizing Equipment and Supplies

A. Stera–Sheen Green Label (or equivalent) prepared to ensure 100ppm of available chlorine (one 1 ounce

packet in one gallon (3.8 l) of water = 100ppm). Solution temperature should be between 80°F and 100°F (26.7°C and 37.8°C).

NOTE: Use potable water at the temperatures listed above. Water above this range will break down the chlorine count and minimize sanitation.

B. One clean 5 gallon (19 l) bucket

C. One clean 1 gallon (3.8 l) bucket

D. Clean, nonabrasive towels/rags

E. A small brush with nylon bristles

F. Three valve fittings cut from three empty BIB bags.

2. Flushing the Concentrate Lines and Valves

A. Cleaning and sanitizing is not required for the potable water circuits. Potable water lines should remain

connected and operational during the cleaning and sanitizing of the juice circuits.

B. Fill the 5 gallon (19 l) bucket with clean, extremely hot tap water, approximately 140°F (60°C).

C. Clean the three valve fittings that were cut from the BIB bags by rinsing them under hot tap water.

D. Connect the bag valve to the bag connector coming from the dispenser and submerse the parts in the

bucket of hot water.

E. Press and hold the dispense button until the concentrate has been fully purged from the product lines and

valves.

NOTE: DO NOT flush more than three valves simultaneously.

F. Once the concentrate is purged, pulse each valve for 15 seconds on then release the button. Repeat this

pulsing for 15 cycles for each circuit being cleaned. Once the 15 cycles have been completed, allow each valve to dispense for 3 continuous minutes.

G. Remove the nozzle and static mixer from the dispenser and rinse them under hot tap water to remove any

excess concentrate. Repeat for each circuit.

H. Replace the nozzles and static mixers into their proper location.

I. Discard any remaining hot water left in the bucket.

3. Cleaning and Sanitizing the Concentrate lines and Valves

A. Prepare 5 gallons (19 l) of Stera–Sheen Green Label cleaning and sanitizing solution (or equivalent) by

mixing one 1 ounce packet per 1 gallon (3.8 l) of potable water. This will provide enough sanitizing solution to clean and sanitize all 6 concentrate circuits for most installations. Installations that have 50 or more feet (not recommended) of concentrate line may require more sanitizing solution.

NOTE: Use potable water between 80 break down the chlorine count and minimize sanitation.

F and 100oF (26.7oC and 37.8oC). Water above this range will

B. Submerse the bag connector and bag valve assembly into the bucket of sanitizing solution.

C. Press and hold the dispense button until sanitizing solution is dispensed through the mixing valve nozzle.

cuit being sanitized. Once the 15 cycles have been completed, allow the sanitizing solution to stand in the product lines and valves for 30 minutes.

E. While waiting, remove the nozzles and static mixers and place them into a separate container with 2 quarts

(1.9 l) of sanitizing solution. Agitate vigorously using the small brush to remove any excess concentrate. Allow the parts to soak for 30 minutes.

F. Clean the dispensing valves mixing chamber (this is the cavity from which the nozzle is removed) with the

brush and sanitizing solution.

G. Replace the nozzles and static mixers into their proper locations and discard the sanitizing solution in

which they were soaked.

NOTE: DO NOT reuse the sanitizing solution used to clean the nozzles and static mixers etc.

H. Activate the dispensing valves for 2 more cycles (15 seconds on and off) with the sanitizing solution then

run the solution continuously through the valves for 2 minutes.

I. Disconnect the bag valves from the bag connectors and reconnect the bag connectors to their appropriate

product bags.

J. Press and hold each dispense button until juice is dispensed from the nozzle. Dispense and discard two 8

ounce (237 ml) cups of juice and verify that there is no chlorine off-taste.
