ELECTRICAL REQUIREMENTS

CAUTION - The brewer must be disconnected from the power source until specified in

The brewer has an attached cordset and requires 2-wire grounded service rated 120 volts ac, 15 amp, single
phase, 60 Hz.

“A" models require 2-wire, grounded service rated 220 - 240 volts ac, 20 amp, single phase, 50 Hz. Proceed
as follows:

Electrical Hook-Up (Model "A" Only)
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. Plug the power cord into the power connector located in the base on the rear of the brewer.

Initial Set-Up.

INITIAL SET-UP

CAUTION - The brewer must be disconnected from the power source throughout the initial set-up, except

when specified in the instructions.

1. Insert an empty funnel into the funnel rails.

2. Place an empty dispenser 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 dispenser.

4. When the flow of water from the funnel stops, connect the brewer to the power source and 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 dispenser and replace it under the funnel.

6. Pour one pitcher of tap water into the screened area on top of the brewer.

7. When water has stopped flowing from the funnel let the water in the tank reheat to the proper temperature.

8. Empty the dispenser. The brewer is now ready for use in accordance with the coffee brewing instructions

below.

NOTE: The control thermostat will need to be adjusted downward to compensate for high altitudes. Refer to

Steaming and spitting around the funnel on page 5 for instructions.

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 dispenser beneath the funnel.

5. Pour one pitcher of tap water into the screened area on top of the brewer.

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 on Bunn-O-Matic equipment.

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.
