INTRODUCTION
This equipment heats and dispenses water on demand for beverages and cooking purposes. It has a
panel above the faucet that indicates the status of the dispenser. This equipment is for indoor use,
either wall-mounted (H5E / X / PC) or on a sturdy counter or shelf.
Brew water temperature is factory set at 200° F (93.3°C)
Areas of high altitude will require lowering this temperature
to prevent boiling. This chart should be used as a guide
when readjusting the brew water temperature.

AC single phase models
1. An electrician must provide electrical service as specified.
2. Using a voltmeter, check the voltage and color coding of each conductor at the electrical source.
3. Turn off master switch (if equipped).
4. Remove the upper and lower rear panels.
5. Install the proper electrical wiring to the terminal block.
6. Connect the dispenser to the power source and verify the voltage at the terminal block before
proceeding. Reinstall both rear panels.
7. If plumbing is to be hooked-up later be sure the dispenser is disconnected from the power source.
If Plumbing has been hooked-up, the dispenser is ready for Initial Setup.
Refer to Data Plate on the Brewer, and local/national electrical codes to determine circuit
requirements.
WARNING - The dispenser must be disconnected from the power source until specified in
Initial Setup.
8
CAUTION - The dispenser must be disconnected from the power source throughout the initial setup,
except when specified in the instructions.
1. Connect dispenser to the power source and turn on water supply.
2. Place Master ON/OFF switch in the ON position (if equipped).
NOTE: (Digital models with display) When power is applied to the dispenser,
the display will show the software version for 5 seconds, and then it will show
the temperature.
3. Water will automatically flow into the tank to the proper level and shut-off.
When filled, the water heater will turn on automatically.
4. The tank will heat to the (set) temperature.
5. Refer to Programming to set the Tank Temperature and the Ready Temperature.
NOTE: On H3 Element only, a small amount of expansion water on back of drip tray is normal during
initial and/or back to back heating cycles.
Plumbing Hook-Up
1. Remove the shipping cap from the fitting on the rear of the dispenser, and attach the flare elbow fitting
(supplied separately with the dispenser) to the fitting (CE/UK inlet 3/4˝ BSP on H3EA Element only).
2. Flush the water line and securely attach it to the flare fitting.
These dispenser must be connected to a COLD WATER system with operating pressure between 20 and
90 psi (0.138 and 0.620 mPa)from a ½˝ or larger supply line. A shut-off valve should be installed in the line
before the dispenser. Install a regulator in the line when pressure is greater than 90 psi (0.620 mPa) to reduce
it to 50 psi (0.345 mPa). The water inlet fitting is ¼˝ flare (CE/UK inlet 3/4˝ BSP on H3EA Element only).
NOTE: Bunn-O-Matic recommends ¼˝ tubing for installations of less than 25 feet and
3
⁄8˝ for more than 25
feet from the ½˝ water supply line. At least 18 inches of an FDA approved flexible beverage tubing, such
as reinforced braided polyethylene or silicone, before the dispenser will facilitate movement to clean the
counter top. Bunn-O-Matic does not recommend the use of a saddle valve to install the dispenser. The size
and shape of the hole made in the supply line by this type of device may restrict water flow.
As directed in the International Plumbing Code of the International Code Council and the Food Code
Manual of the Food and Drug Administration (FDA), this equipment must be installed with adequate
backflow prevention to comply with federal, state and local codes. For models installed outside the
U.S.A., you must comply with the applicable Plumbing /Sanitation Code for your area.
