Installation (cont.)

Electrical Hook-up:

Ensure water connection is made to machine before proceeding

The electrical ratings for your dispenser are located on the serial plate on the outside cabinet.  For configuration of
three heater models to optional wattages, refer to configuration manual 62210 supplied with the machine.

1. For cord connected models, plug the power cord into an appropriate grounded and dedicated electrical outlet.

Go to step 8.

2. For hard-wired models not supplied with a can electrical cord, the dispenser should be connected to a dedicated

circuit with a fused disconnect switch or a circuit breaker near the dispenser.

3. Strain relief knockouts are supplied on the back of the machine chassis for power entry.

•  Electrical connections and wiring materials must conform to local codes and/or be in compliance with

the National Electric Code

•  Use only copper conductors

4. Remove the access panel located on the upper left side of the dispenser.  Note: wiring diagram is on backside

of access panel.

5. Connect the power supply conductors, neutral and ground wire to the appropriate positions on the terminal block

located on the upper left side of the dispenser.  The ground lug is separate from the terminal block.  Note: if
power supply available does not provide for a neutral conductor, a stepdown transformer must be installed to
provide the necessary 120 volt power supply for the control circuits.  Consult factory for assistance.

6. Install the side access panel.
7. Flip power supply to machine “ON” at the branch supply disconnect.
8. Flip power switch to the “ON” position and allow the water tank to fill.  The machine will make a subtle hissing

sound while filling.  Allow 3-4 minutes for fill time depending on water pressure.

9. After the water tank has completed the fill cycle, the green Ready light located on the front of the dispenser

should extinguish signifying that the heating element has been activated.  Allow 10-60 minutes for the Ready light
to illuminate signifying the water tank has reached operating temperature. (Note: Heatup time is dependent on
water inlet temperature and input wattage to the machine.)

Bag-in-Box Hook-up

1. Place bag-in-box containers inside the cabinet behind the front door.  Connect the quick connect fitting to each

bag-in-box.

2. After connecting the bag-in-box, flip the water switch located behind the front door to the “OFF” position and flip

the concentrate switch to the “ON” position.

3. Activate the appropriate dispense switch on the front of the door in order to prime the concentrate lines with

product.  Continue to activate the dispense switch until concentrate is dispensed from the appropriate dispense
spout.

4. Repeat steps for other dispense spout.
5. Flip water switch back to “ON” position.
6. Close front door and ensure that both water and product are dispensed simultaneously.

How to Dispense a Cup of Coffee

Attention:  This machine employs an interlock switch to disable the dispense and fill circuits
when the front door is open.  Ensure the front door is closed while installing or operating the
machine.  A watchdog circuit also monitors the water level in the tank and will disable the
machine if the water level in the tank is not normal within (5) minutes of fill time.  The machine
will require power to be reset to clear the watchdog timeout.

WARNING:

Do not use cups over 6 3/4" (15.2 cm) tall with this machine.  Use of cups over this height could

result in severed burns and injury.
