Installation

Water Inlet Connection:

The National Sanitation Foundation requires the following for an NSF approved water hook-up:

1. A quick disconnect water connection or enough coiled tubing so that the machine can be moved for cleaning
underneath.

2. An approved backflow prevention device, such as a double check valve to be installed between the machine and
water supply. A1/4" male flare adapter is provided (packed inside drain tray) to be attached by installer to the
back of the machine for hook-up to water supply. On units plumbed to permanent water line, installation of a water
filter/softener system is recommended to prevent lime and scale build up in the machine. On units pumping from
remote water container, filtered water is recommended to prevent lime and scale buildup in the machine.

3. Water pipe connections and fixtures directly connected to potable water supply shall be sized, installed and

maintained in accordance with Federal, State, and Local codes.

Water hook-up:

1. Install the (2) front 4" legs to provide approximately 1/2" clearance with the bottom of the machine.

2. Install drain tray bracket to the front of the machine by sliding the bracket between the front 4" legs and the
bottom of the machine. The bracket should self locate with screw heads on the bottom of the machine. Tighten
the front 4" legs to secure the drain tray bracket.

3. Install the (2) back 4" legs and tighten.

4. Install the plastic drain tray onto the drain tray bracket. (Note: The drain tray is provided with a removable plug to
allow for plumbing the drain tray to a drain.)

5. Connect the metal swivel fitting provided to a flexible water supply hose. Ensure the water supply hose has
sufficient length to allow the machine to be moved for cleaning or service. Supplying hot water to the machine will
greatly increase the capacity of the machine. The use of copper tubing is required to prevent rupture when using
a hot water supply. Amaximum inlet water temperature of 160Þ F is recommended.

6. Ensure that the water supply to the machine is within 20 to 100psi. Install a pressure regulator if pressure is too
high.

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.
