Frequently Asked Questions - H3XA Element Bunn

How do I install the Bunn H3XA Element water dispenser?

Installation requires a cold water line with pressure between 20-90 psi. Connect using a 1/4" flare fitting (3/4" BSP for CE/UK models). An electrician must connect to a properly grounded circuit per local codes. For wall mounting (5-gallon models only), use Bunn bracket kit #12542.0000 or #13125.0001.

How do I adjust the water temperature on the H3XA Element?

Ensure the program lockout switch is in the "SET" position. Press and hold the hidden button (under BUNN logo) until P1 appears, then use +/- to adjust set temperature (range 60°F-212°F). Press hidden button again to set ready temperature (2°F-20°F below set temp). Confirm by pressing hidden button to exit.

What does the Energy Saver Mode do and how do I activate it?

Energy Saver Mode reduces tank temperature to 140°F (60°C) or turns the heater off to save power. It can be activated manually by pressing + and - simultaneously on the H3XA Element. In programming (P4-P6), you can enable auto mode and set a delay from 4 to 24 hours after the last water use.

How do I drain the water tank for cleaning or storage?

Disconnect the dispenser from power and let it cool. For OHW models: tilt forward over sink and open faucet. For other models: remove rear access cover, close shutoff clamp on inlet hose, disconnect hose from solenoid, and drain into a container (min 2 gallons for HW2, 5 gal for H5, 10 gal for H10). Replace hose and clamp after draining.

Why is water not dispensing from my H3XA Element?

Check that the unit is powered on and the tank is full. Verify that dispense lockout (if enabled) is not active—the tank temperature must be above the ready temperature setting. Ensure the program lockout switch is not in "LOCK" position. Also check water supply shut-off valve and inlet filter for blockages.

How do I clean the H3XA Element dispenser?

Use a damp cloth with mild, non-abrasive liquid detergent to wipe all exterior surfaces. Do not immerse the unit or use a pressure washer. For internal cleaning, follow the draining procedure and then refill with fresh water. Regular cleaning prevents mineral buildup.

Can I use the H3XA Element at high altitudes?

Yes, but the brew water temperature must be adjusted to prevent boiling. Refer to the altitude chart in the manual: e.g., at 5000 ft, set temperature to 195°F (90.6°C). The factory default is 200°F (93.3°C) for sea level.

What is the warranty for the Bunn H3XA Element?

Bunn warrants commercial equipment for 2 years parts and 1 year labor. Electronic control boards are covered for 3 years parts and labor. Compressors have 5 years parts and 1 year labor. Warranty covers defects in material/workmanship but excludes misuse, improper installation, or normal wear items like seals.

How do I reset the H3XA Element to factory defaults?

Enter Level 2 programming by pressing and holding the hidden button until H2 appears. Press again to see H3 and "---". Press and hold both + and - buttons simultaneously until "don" appears. This clears all custom settings and restores factory defaults.

What electrical supply does the H3XA Element require?

The H3XA Element can be configured for 120 V AC (15.4 A, 1850 W) or 120/208-240 V AC (16.9 A, 4050 W). Check the data plate on your unit. It requires a dedicated circuit with proper grounding. For 120V models, use a 2-wire + ground supply; for 208-240V, use 3-wire + ground.

ELECTRICAL HOOK-UP

CAUTION – Improper electrical installation will damage electronic components.

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.

PLUMBING REQUIREMENTS

- ALL EXCEPT OHW -

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 12'' 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 14'' flare (CE/UK inlet 3/4" BSP on H3EA Element only).

NOTE: Bunn-O-Matic recommends 14 " tubing for installations of less than 25 feet and 38 " for more than 25 feet from the 12 " 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.

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.

INITIAL SETUP
