Frequently Asked Questions - Refresh Bunn

How do I clean the Bunn Refresh water dispenser?

To clean, unplug and empty the reservoir. Mix a solution of white vinegar and water (1:1) and fill the reservoir. Let it sit for 30 minutes, then drain and rinse thoroughly with fresh water.

How often should I replace the water filter?

The built-in carbon filter should be replaced every 6 months or after 300 gallons of use, whichever comes first.

Why is my water dispenser not dispensing hot water?

Ensure the unit is plugged in and the hot water switch is turned on. If still no hot water, the heating element may need resetting or the unit may have tripped a safety thermostat. Refer to manual.

Can I use bottled water in the Bunn Refresh?

Yes, the dispenser can be used with bottled water (5-gallon jugs) or plumbed directly to a water line if a kit is installed.

What is the temperature of the hot water?

Hot water is dispensed at 185°F to 200°F (85°C to 93°C), ideal for tea or instant coffee.

How do I remove the drip tray for cleaning?

The drip tray is removable. Simply slide it forward and lift it off. Wash with warm soapy water and dry before reinstalling.

My dispenser is making unusual noises. What could be wrong?

Noises may be due to air in the water line or the cooling compressor cycling. If persistent, check that the unit is level and the reservoir is full.

Is the hot water tap safe for children?

The dispenser includes a child safety lock on the hot water tap. Press and hold the lock button while dispensing to prevent accidental use.

How do I descale the water dispenser?

Use a commercial descaling solution or white vinegar. Fill the reservoir, let it sit for 30 minutes, then flush with fresh water. Repeat as needed.

What should I do if the unit leaks?

Check if the water bottle is properly seated or the drip tray is full. If leaking from the bottom, turn off and unplug, then contact Bunn support.

INITIAL SET-UP

CAUTION: The dispenser is very heavy! Use care when lifting or moving it. Use at least two people to lift or move the dispenser. Place dispenser on a sturdy counter or shelf able to support at least 125 lbs. (57 kg).

The dispenser is designed for indoor use only, in ambient temperatures ranging from 50^ F to 90^ F ( 10^ C to 32^ C). Avoid locating the machine where it will be subject to direct sunlight or exposed to other external heat sources. Allow a minimum clearance of 6" at the back and top of the dispenser, and a minimum of 4" at either side of the dispenser for proper air circulation. Leave some space so the dispenser can be moved for cleaning.

ELECTRICAL REQUIREMENTS

CAUTION: The dispenser must be disconnected from the power source until specified in Electrical Hook-Up.

The 120V rated dispensers have an attached cord set and require a 2-wire, grounded, individual branch circuit rated 120 volts ac, 15 amp, single phase, 60Hz. The mating connector must be a NEMA 5-15R.

Refer to the data plate for exact electrical requirements.

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. Confirm that the compressor switch and the dispense switch are in the OFF position (see Figure 1).
4. Connect the dispenser to the power source.
5. 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 Fill.

Figure 1
P4373

PLUMBING REQUIREMENTS

The dispenser must be connected to a COLD WATER system with an operating pressure between 30 and 100 psig (.207 and .690 mPa). This water source must be capable of producing a minimum flow rate of 3 fluid ounces (88.7 milliliters) per second. A shut off valve should be installed in the line that will supply the dispenser. A water filter has been included with the dispenser. The water filter should be installed as close as possible to the inlet of the machine, but downstream of the shut off valve (see Figure 2). The new water filter should be flushed with at least five gallons of water before hooking it up to the dispenser. The main water inlet is a 3/8" (9.52 mm) MFL connection.

NOTE- At least 18 inches (457 mm) of an FDA approved flexible beverage tubing, such as reinforced braided polyethylene, before the dispenser will facilitate movement to clean the countertop. It can be purchased direct from BUNN-O-MATIC (part number 45848.10____[see Illustrated Parts Catalog for complete part number.]) BUNN-O-MATIC does not recommend the use of saddle valves to install the dispenser. The size and shape of the hole(s) made in the supply line(s) by saddle valves may restrict water flow.

Figure 2

P4372

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

The plumbing connection is a 3/8" male flare adapter located on the rear of the water dispenser (Figure 3).

NOTE – Water pipe connections and fixtures directly connected to a potable water supply shall be sized, installed, and maintained in accordance with federal, state, and local codes.

Figure 3

CARBON DIOXIDE HOOK-UP

The dispenser will need to be connected to an external CO_2 source. An external CO_2 pressure regulator will need to be installed in the supply line to the dispenser. The external CO_2 supply connection is a 14 " MFL (Figure 4) located on the back of the machine.

FILLING THE WATER BATH

1. Plug the dispenser into an electrical outlet and turn on the water supply to the dispenser.
2. Flip the dispense switch to ON. The water bath will begin to fill. The water bath will fill and automatically shut off when the water bath is full.
3. Check the sight glass to confirm that the water bath is full (See Figure 5).

Once the water bath is full, flip the compressor switch to ON. It will take several hours to create the ice bank required for full dispenser performance, but there will be chilled water in one to two hours. During this time, some further trickling from the water bath into the drip tray is expected due to expansion caused by the ice bank formation.

CHANGE WATER FILTER CARTRIDGE WARNING

The water filter cartridge will need to be changed after 4,500 gallons of use. When the water usage gets close to 4,500 gallons, the blue LED will flash slowly to indicate that it is nearly time to replace the water filter cartridge. When the water usage exceeds 4,500 gallons, the blue LED will flash rapidly to indicate that it is time to replace the water filter cartridge. Once the water filter cartridge has been replaced, push and hold the water filter reset switch for 3 seconds to clear the warning.

CHANGING THE WATER FILTER CARTRIDGE:

1. To change the water filter cartridge, shut off the water supply line and remove the water supply line at the dispenser.
