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. 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 4" legs and hand tighten. Install the plastic drain tray onto the drain tray bracket and install drain grid. (Note: The drain tray is provided with a drill-out port to allow for plumbing to a drain.)

2. Remove front splash panel for access to water hook-up. (see Figure 1)

3. Ensure the 3/8" 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. A maximum inlet water temperature of 160°F (71°C) is recommended.

4. Flush the water line to purge any debris from the supply line.

5. Connect a 3/8" water line to the 3/8" male flare connection.

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

7. Turn on water supply and check for leaks.

WARNING: ELECTRIC SHOCK HAZARD

Only qualified service personnel should perform installation of this appliance. Improper installation could result in serious injury or death.

WARNING: ELECTRIC SHOCK HAZARD

Always disconnect power to the machine before servicing or cleaning. Risk of electric shock is present which can cause serious injury or death.

WARNING: ELECTRIC SHOCK HAZARD

Never use the ground conductor as a neutral conductor. Serious injury or death could occur in the event of a fault condition.

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 and inside door. For configuration of three heater models to optional wattages, refer to page 31 of service manual.

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 an 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 is supplied under the machine chassis for power entry. (see Figure 2)

• 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. Note: Wiring diagram is on inside of left side panel.

5. Connect the power supply conductors, neutral (optional) and ground wire to the appropriate positions on the terminal block. The ground lug is separate from the terminal block. Note: machine is equipped with a stepdown transformer to provide the necessary 120 volt power supply for the control circuits. Neutral will not be used.

6. Remove lid and left side panel. (see Figure 3)

7. Install the front splash panel.

8. Install the plastic drain tray into the drain tray rails then place drain grid onto drain tray.

9. Flip power supply to machine “ON” at the branch supply disconnect.

10. 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.

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.

11. After the water tank has completed the fill cycle, the display will read “Water Heating” signifying that the heating element has been activated. Allow 10-45 minutes for the display to read “Ready” signifying the water tank has reached operating temperature. (Note: Heatup time is dependent on water inlet temperature and input wattage to the machine.)
