Electrical Hook-Up
CAUTION – Improper electrical installation will damage electronic components.
1. An electrician must pro ide electrical ser ice as specified.
2. Remo e the top lid and rotate the control thermostat knob fully counterclockwise to the “OFF” position and
reinstall the top lid.
3. Remo e 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 oltmeter, check the oltage and color coding of each conductor at the power source.
5. Connect the brewer to the power source and erify the oltage 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 pro ide 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 1⁄2" or larger supply line. A shut-off al e 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 1⁄4" flare.
NOTE - Bunn-O-Matic recommends 1⁄4" copper tubing for installations of less than 25 feet and 3⁄8" for more than
25 feet from the 1⁄2" water supply line. A tight coil of copper tubing in the water line will facilitate mo ing the
brewer to clean the countertop. Bunn-O-Matic does not recommend the use of a saddle al e to install the
brewer. The size and shape of the hole made in the supply line by this type of de ice 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 Ser ice 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. Remo e 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.

INITIAL SET-UP (cont.)
Water will flow into the tank and dispenser for fi e minutes and forty-fi e 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, remo e the rear trunk panel, and turn the handle on the needle
al e approximately one-quarter turn counterclockwise to enable the flow of dilution water. This al e 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 essel than
the one used for the water flowing from the funnel.
7. Place a essel under the brew funnel to catch the brew water. Use a hose or other means to di ert 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 olume 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 al e 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 olume (twenty-two ounces) is achie ed.
11. Disconnect the brewer from the power source and reinstall the rear trunk panel.
12. Unplug the brewer, remo e 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 olume 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 olume is achie ed.
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 remo al 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 ser er are in place.
1. Modifying batch sizes. To modify a batch olume, 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 olume setting to be
aborted and pre ious olume 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 erify that the desired olume has been achie ed.
To decrease a batch size. Press and release the START or BREW switch once for e ery two-second inter al

Page 5 10792 091701
ADJUSTING BREW VOLUMES (cont.)
to be remo ed 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 olume setting to be aborted and pre ious olume setting will remain in memory).
Allow the brew cycle to finish in order to erify that the desired olume has been achie ed.
2. Setting batch sizes. To set a batch olume, 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 olume setting to be aborted and pre ious olume setting will remain in memory). View
the le el of the liquid being dispensed. When the desired le el is reached, turn the ON/OFF switch to “OFF”
(lower). The brewer remembers this olume and will continue to brew batches of this size until the olume
setting procedure is repeated.
NOTE: When brewing tea, batch olumes will decrease due to absorption by the tea lea es.
3. Setting programming disable feature. If it becomes necessary to pre ent anyone from changing brew times
once programmed, you can set the SET/LOCK switch to the “LOCK” position. This will pre ent 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. Remo e 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. Remo e 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 isible and mo e it in and
out 5 or 6 times. Insert the spring into the air ent hole in the sprayhead panel and mo e 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 o ernight. 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 acti ate 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 le el.
NOTE - The switch should always be placed in the “OFF” position after a brew cycle and whene er 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.
