ELECTRICAL REQUIREMENTS

CAUTION - Do notplug-inthe brewer until specified in InitialSet-Up.

The A10 Automatic Brewer has an attached cordset and requires 2-wiregrounded service rated 120 volts ac, 10 amp, single phase, 60 Hz.

The A10A Automatic Brewer has an IEC 320 connector and matching cordset and requires 2-wiregrounded service rated 230 volts ac, 10 amp, single phase,50-60Hz. The appropriate cordset connector must be supplied when installing the brewer.

PLUMBING REQUIREMENTS

This brewer must be connected to a cold water system with operating pressure between 20 and 90 psi from a 1/2" or larger supply line. Ashut-offvalve should be installed in the line before the brewer. Install a regulator in the line when pressure is greater than 90 psi to reduce it to 50 psi. The water inlet fitting is1/4" flare.

NOTE Bunn-O-Maticrecommends1/4" copper tubing for installations of less than 25 feet and3/8" for more than 25 feet from the1/2" water supply line. At least 18 inches of an FDA approved flexible beverage tubing, such as reinforced braided polyethylene or silicone, before the brewer will facilitate movement to clean the countertop. It can be purchased direct fromBunn-O-Matic(part number00326-0000).

This equipment must be installed to comply with the Basic Plumbing Code of the Building Officials and Code Administrators International, Inc. (BOCA)

and the Food Service Sanitation Manual of the Food and Drug Administration (FDA).

Plumbing Hook-Up

1.Attach the flare fitting from the short piece of tubing on the flow control (supplied) to the water inlet fitting on the left rear side of the brewer.

2.Flush the water line and securely attach it to the flare fitting on the strainer.

3.Turn on the water supply.

INITIAL SET-UP

CAUTION Thebrewer must be unplugged throughout the initialset-up,except when specified in the instructions.

1.Insert an empty funnel into the funnel rails.

2.Place an empty decanter under the funnel.

3.Pour three pitchers of tap water into the screened area on top of the brewer. Allow approximately two minutes between pitchers for water to flow into the tank. While the third pitcher of water is entering the tank, the tank will fill to capacity and the excess will flow from the sprayhead, out of the funnel, and into the decanter.

4.When the flow of water from the funnel stops, plug-inthe brewer and place the heater switch on the left side of the brewer in the “ON” lower position. Wait approximately twenty minutes for the water in the tank to heat to the proper temperature. Some water will drip from the funnel during this time; this is due to expansion and should not occur thereafter.

5.Empty the decanter, return it to the warmer, place the warmer switch in the “ON” (lighted) position, and momentarily press and release the start switch.

6.Place the warmer switch in the “OFF” (unlighted) position after water has stopped flowing from the funnel, and let the water in the tank reheat to the proper temperature.

7.Empty the decanter, place the warmer switch in the “ON” (lighted) position, and momentarily press and release the start switch. Check the water volume in the decanter after water has stopped flowing from the funnel. It should be 48 ounces.

INITIAL SET-UP(CONT.)

8.If not, locate the brew timer near the heater switch on the left side of the brewer, adjust the brew timer dial up-or-downas required and allow the water to reheat. Start, and measure another brew cycle.

9.Repeat step 8 until 48oz water volume is achieved.

10.The brewer is now ready for use in accordance with the coffee brewing instructions.

OPERATING CONTROLS

Warmer Switch

Placing the switch in the unlighted position cuts power to the brew station warmer and stops brewing. Stopping a brew cycle after it has been started will not stop the flow of water into the funnel until the tank syphons down to its proper level. Placing the switch in the lighted position supplies power to the brew station warmer and enables the brew circuit.

Start

Momentarily pressing and releasing this switch starts a brew cycle when the warmer switch is in the lighted position.

NOTE Thewarmer switch must be in the lighted position to initiate and complete a brew cycle.

Full/Half

Placing this switch in the half position yields approximately 24 ounces.

COFFEE BREWING

1.Insert a BUNN® filter into the funnel.

2.Pour the fresh coffee into the filter and level the bed of grounds by gently shaking.

3.Slide the funnel into the funnel rails.

4.Place an empty decanter under the funnel.

5.Place the warmer switch in the lighted position. Momentarily press and release the start switch.

6.When brewing is completed, simply discard the grounds and filter.

CLEANING

1.The use of a damp cloth rinsed in any mild, non-abrasive,liquid detergent is recommended for cleaning all surfaces onBunn-O-Maticequipment.

2.Check and clean the sprayhead. The sprayhead holes must always remain open.

3.With the sprayhead removed, insert the deliming spring (provided) all the way into the sprayhead tube. When inserted properly, no more than two inches of spring should be visible. Saw back and forth five or six times.

NOTE – In hard water areas, this may need to be done daily. It will help prevent liming problems in the brewer and takes less than a minute.
