Electrical Hook-Up

CAUTION – Improper electrical installation will damage electronic components.

1. An electrician must provide electrical service as specified.

2. Remove the top lid and rotate the control thermostat knob fully counterclockwise to the “OFF” position and

reinstall the top lid.

3. Remove the rear trunk panel, feed the cord through the strain relief at the rear of the brewer and connect it to

the terminal block.

4. Using a voltmeter, check the voltage and color coding of each conductor at the power source.

5. Connect the brewer to the power source and verify the voltage at the terminal block and reinstall the rear

trunk panel.

6. If plumbing is to be hooked up later be sure the brewer is disconnected from the power source. If plumbing

has been hooked up, the brewer is ready for Initial Set-Up.

WARNING – The brewer must be electrically grounded using the green screw near the terminal block. Do not

assume a plumbing line will provide an adequate ground.

PLUMBING REQUIREMENTS

This brewer must be connected to a cold water system with operating pressure between 30 (207 kPa) and 90

psi (620 kPa) from a ⁄2" or larger supply line. A shut-off valve should be installed in the line before the brewer.

Install a regulator in the line when pressure is greater than 90 psi(620 kPa) to reduce it to 50 psi (345 kPa). The

water inlet fitting is ⁄4" flare.

NOTE - Bunn-O-Matic recommends ⁄4" copper tubing for installations of less than 25 feet and ⁄8" for more than

25 feet from the ⁄2" water supply line. A tight coil of copper tubing in the water line will facilitate moving the

brewer to clean the countertop. Bunn-O-Matic does not recommend the use of a saddle valve to install the

brewer. The size and shape of the hole made in the supply line by this type of device may restrict water flow.

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 female fitting from the short piece of tubing on the strainer assembly (supplied) to the water inlet

fitting on the rear of the brewer.

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

3. Turn on the water supply.

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. Remove the top lid from the brewer.

2. Rotate the control thermostat knob fully counterclockwise to the "OFF" position and replace the top lid.

3. Insert an empty funnel into the funnel rails.

4. Place an empty dispenser on the brewer base. Be prepared to empty the dispenser during these initial steps.

5. Plug in the brewer, place the ON/OFF switch in the "ON" position, and momentarily press the START switch.

10792 021594

INITIAL SET-UP (cont.)

Water will flow into the tank and dispenser for five minutes and forty-five seconds. Empty the dispenser

when this first cycle stops and press the START switch again. Empty the dispenser when the second cycle

stops and press the START switch once more. During the third cycle, the tank will fill to its capacity and the

excess will flow from the funnel into the dispenser. Empty the dispenser when this third cycle stops.

6. Disconnect the brewer from the power source, remove the rear trunk panel, and turn the handle on the needle

valve approximately one-quarter turn counterclockwise to enable the flow of dilution water. This valve is fully

closed at the factory.

NOTE - The next step requires the use of a stopwatch to calculate the amount of dilution water flowing from the

nozzle in one minute. You’ll need to capture and measure the timed dilution water in a separate vessel than

the one used for the water flowing from the funnel.

7. Place a vessel under the brew funnel to catch the brew water. Use a hose or other means to divert the water

from the dilution nozzle to a separate container.

8. Connect the brewer to the power source. Simultaneously press the start switch to begin another brew cycle

and start the stop watch. Place the ON/OFF switch in the “OFF” position at exactly sixty-seconds (one-

minute). When the flow of water stops, measure the volume of the captured dilution water. It should be

approximately twenty-two ounces.

9. If not, disconnect the brewer from the power source, and adjust the handle on the needle valve clockwise to

decrease the amount of water or counterclockwise to increase the amount of dilution water as required.

10. Repeat steps 8 & 9 until the recommended dilution water volume (twenty-two ounces) is achieved.

11. Disconnect the brewer from the power source and reinstall the rear trunk panel.

12. Unplug the brewer, remove the top lid, rotate the control thermostat knob fully clockwise to the "ON" position

and replace the top lid.

13. Empty the dispenser.

14. Connect the brewer to the power source and wait for the ready light to glow indicating the water in the tank

has heated to brewing temperature (approximately 20 minutes). Some water will drip from the funnel during

this time; this is due to expansion and should not occur thereafter.

15. Begin another brew cycle and measure the total water volume from the dispenser. It should be approximately

3 gallons and 12 ounces. (396 ounces).

16. If not adjust the timer as required. See Adjusting Brew Volumes.

17. Start, and measure another cycle.

18. Repeat steps 16-17 until the recommended total water volume is achieved.

19. The brewer is now ready to brew a batch of freshly brewed room temperature coffee.

ADJUSTING BREW VOLUMES

CAUTION - Disconnect the power source from the brewer prior to the removal of any panel for the replacement

or adjustment of any component.

NOTE: Prior to setting or modifying batch sizes, check that the brewer is connected to water supply, the tank is

properly filled, and a funnel and server are in place.

1. Modifying batch sizes. To modify a batch volume, first check that the SET/LOCK switch is in the “SET”

position on the circuit board.

To increase a batch size. Press and hold the START or BREW switch until three clicks are heard. Release the

switch (Failure to release the switch within two seconds after the third click causes the volume setting to be

aborted and previous volume setting will remain in memory) and press it again one or more times. Each time

the switch is pressed, two seconds are added to the brew time period. Allow the brew cycle to finish in order

to verify that the desired volume has been achieved.

To decrease a batch size. Press and release the START or BREW switch once for every two-second interval

10792 091701

ADJUSTING BREW VOLUMES (cont.)

to be removed from the total brew time period; then immediately press and hold down the START or BREW

switch until three clicks are heard. Release the switch. (Failure to release the switch within two seconds after

the third click causes the volume setting to be aborted and previous volume setting will remain in memory).

Allow the brew cycle to finish in order to verify that the desired volume has been achieved.

2. Setting batch sizes. To set a batch volume, first check that the SET/LOCK switch is in the “SET” position on

the circuit board. Press and hold the START or BREW switch until three distinct clicks are heard (approxi-

mately 10 seconds) and then release the switch. (Failure to release the switch within two seconds after the

third click causes the volume setting to be aborted and previous volume setting will remain in memory). View

the level of the liquid being dispensed. When the desired level is reached, turn the ON/OFF switch to “OFF”

(lower). The brewer remembers this volume and will continue to brew batches of this size until the volume

setting procedure is repeated.

NOTE: When brewing tea, batch volumes will decrease due to absorption by the tea leaves.

3. Setting programming disable feature. If it becomes necessary to prevent anyone from changing brew times

once programmed, you can set the SET/LOCK switch to the “LOCK” position. This will prevent any program-

ming to be done until switch is once again placed in the “SET” position.

CLEANING

CAUTION - Clean and sanitize your iced coffee brewer daily

1. Remove and thoroughly clean the entire brew funnel. The funnel must be free from any coffee particles or

residue.

2. Disconnect the brewer from the power source. Remove and thoroughly rinse the sprayhead. Wipe the

sprayhead panel clean with a damp cloth.

3. Insert the deliming spring into the sprayhead fitting until no more than one inch is visible and move it in and

out 5 or 6 times. Insert the spring into the airvent hole in the sprayhead panel and move it in and out 5 or 6

times. Reattach the sprayhead.

4. Wash the entire outside surface of the brewer with a clean damp cloth.

CAUTION - Do not keep brewed coffee overnight. The dispenser must be cleaned and sanitized daily.

OPERATING CONTROLS

A. Lighted On/Off Switch

ON - Placing the switch in the lighted upper position allows the start switch to activate a brew cycle.

OFF - Placing the switch in the lower position stops the brew cycle. 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.

NOTE - The switch should always be placed in the “OFF” position after a brew cycle and whenever the brewer is

unattended.

B. Full/Half Batch Selector Switch

Full - Placing the switch in the upper position produces a full batch of room temperature coffee from the brew

cycle.

Half - Placing the switch in the lower position produces half of a full batch of room temperature coffee from the

brew cycle.

C. Start Switch

Starts a brew cycle when the lighted On/Off switch is in the “ON” position.
