Frequently Asked Questions - H3X Element Bunn

How do I set the water temperature on the Bunn H3X Element?

Press and hold the hidden programming button (under the BUNN logo) until the display shows P1. Use the + or - buttons to adjust the set temperature (range 60°F-211°F). Press the hidden button again to set the ready temperature differential.

What is the energy saver mode 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. Manually activate by pressing + and - simultaneously. For auto mode, program it via the hidden button sequence (P4-P6).

How do I clean the Bunn H3X Element dispenser?

Use a damp cloth with mild, non-abrasive detergent to wipe all surfaces. Do not immerse the unit or clean with a pressure washer. Regular cleaning prevents scale buildup.

What should I do if the water is not hot enough?

Check the set temperature in programming (P1). Ensure the ready temperature differential (P2) is not too large. Also verify the power supply and that the unit has finished heating. At high altitudes, lower the set temperature to avoid boiling.

What is the warranty coverage for the H3X Element?

Bunn warrants the equipment for 2 years parts and 1 year labor. Electronic circuit boards are covered for 3 years parts and labor. The warranty excludes misuse, improper installation, poor water quality, and normal wear items like seals.

Can I dispense hot water continuously?

Yes, by default the dispenser provides continuous flow while the faucet handle is held open. If portion control is needed, you can program a set dispense volume (P7 setting) or use the optional portion control model (H5-PC).

What type of electrical connection does the H3X Element require?

The unit can be configured for 120V AC (2-wire + ground) or 120/208-240V AC (3-wire + ground), 60Hz. Refer to the data plate for exact amperage and voltage. A qualified electrician must install according to local codes.

How do I drain the water tank for maintenance?

Disconnect power and allow cooling. For 3-gallon models, remove rear access panel, close the white clamp on the hose between tank and solenoid, disconnect the hose, and drain into a container. Reconnect after emptying. Never operate without water.

Is the H3X Element suitable for home use?

Yes, it is intended for commercial and household use in kitchens, break rooms, and similar environments. However, it must be installed by qualified personnel and used under supervision. Children under 18 should not operate it.

How do I reset the factory defaults?

Enter Level 2 programming by holding the hidden button until H1 appears. Press the button to cycle to H3, then press and hold both + and - buttons until the display shows 'don'. This clears all custom settings.

DUAL VOLT TOGGLE SWITCH

PLUMBING REQUIREMENTS - ALL EXCEPT OHW

This 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 countertop. 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.
