PLUMBING REQUIREMENTS
These brewers must be connected to a cold water system with operating pressure between 20 and 90 psi
1
(138 and 620 kPa) from a
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 fi tting is
deionized water supply to this equipment.
NOTE - Bunn-O-Matic recommends
25 feet from the 1⁄2" water supply line. A tight coil of 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 fl ow.
This equipment must be installed to comply with the Basic Plumbing Code of the
Building Offi cials and Code Administrators International, Inc. (BOCA)
and the Food Service Sanitation Manual of the Food and Drug Administration (FDA).
Plumbing Hook-Up
1. Flush the water line.
2. Securely attach the Strainer/Flow Control and tube assembly to the water supply line.
3. Securely attach tube assembly to the fl are fi tting at the rear of the brewer.
4. Turn on the water supply.
⁄2" or larger supply line. A shut-off valve should be installed in the line before the

INITIAL SET UP
CAUTION - The brewer must be disconnected from the power source throughout the initial set-up, except when
specifi ed in the instructions.
1. Insert an empty funnel into the funnel rails. (FIG 4)
2. Place an empty server under the funnel. For taller servers, lift up on the front of the booster plate, and slide
it back into the trunk housing.
NOTE: If more height is need, the legs may be extended to a maximum of 1¾˝. (FIG 5)
3. Connect the brewer to the power source.
4. Press and release the "ENABLE BREW ON/OFF" switch. (Indicator/Display must be lit!). Water will fl ow into
the tank and stop when the tank is fi lled to its capacity.
5. Wait approximately twenty minutes for the water in the tank to heat to the proper temperature. Display will
show "READY" (green light on Silver Series) when tank is at operating temperature. Some water will drip
from the funnel during this time; this is due to expansion and is normal part of setup.
6. Water volumes and fl ow settings have been preset at the factory. Refer to Adjustments Section of this manual
to set brew volumes should the volume need to be increased or decreased.
7. The brewer is now ready for use in accordance with the instructions for Coffee Brewing.

(A) ENABLE BREW ON/OFF SWITCH
Pressing the "ENABLE BREW ON/OFF" switch (indicator on) enables the brew circuit, and energizes the tank refi ll
circuit. Pressing the switch again (indicator off) stops tank refi lling and brewing. Stopping a brew cycle after
it has been started will not stop the fl ow of water into the server until the funnel is empty.
NOTE 1: – Stopping a brew cycle by pressing the "ENABLE BREW ON/OFF" switch to the "OFF" position, will disable the tank refi ll circuit. If the level is low enough, tank heating may be disabled as well. Simply pressing the
"ENABLE BREW ON/OFF" switch to the "ON" position will allow the tank to replenish. Allow a few minutes for the
tank to heat back up to it's ready temperature.
NOTE 2: – Hot water will be available at the faucet in a limited amount when the "ENABLE BREW ON/OFF" switch
is in the "OFF" position because the tank will not refi ll. Refer to NOTE 1 regarding low level.
(B) SMALL BREW SWITCH
Momentarily pressing and releasing the switch starts the selected "SMALL" brew cycle when the "ENABLE BREW
ON/OFF" indicator is on. (Factory set for approx. 64 ounces)
(C) LARGE BREW SWITCH
Momentarily pressing and releasing the switch starts the selected "LARGE" brew cycle when the "ENABLE BREW
ON/OFF" indicator is on. (Factory set for approx. 64 ounces)
(D) STATUS INDICATOR

BREW VOLUME SET-UP:
NOTE: Set small and large batches separately. Maximum water on time is 5 minutes.
Use the following steps when the setting is unknown.
1. Place an empty funnel in the funnel rails and an empty server beneath the funnel.
2. Press the "ENABLE BREW ON/OFF" switch ("ON").
3. Press and hold the small brew start switch until the LED indicator alternately fl ashes red/green (approximately
15 seconds). Release the switch.
4. Allow the cycle to continue until the desired amount of water is dispensed and then press the "ENABLE BREW
ON/OFF" to turn "OFF" the brewer.
The brewer is now set to dispense this amount of water for each subsequent small brew cycle.
To increase the amount of water for each brew cycle place an empty funnel in the funnel rails and an empty
server beneath the funnel. Press the "ENABLE BREW ON/OFF" switch (ON). Press and hold the small "BREW"
switch until you hear the solenoid click on-and-off three times (approximately 10 seconds), then release the small
"BREW" switch. Momentarily press and release the small "BREW" switch once for each ounce (approximate) of
water to be added to the prior setting and allow the brew cycle to fi nish.
To decrease the amount of water for each brew cycle place an empty funnel in the funnel rails and an empty
server beneath the funnel. Press the "ON/OFF" switch (ON). Momentarily press and release the small "BREW"
switch once for each ounce (approximate) of water to be removed from the existing setting. Press and hold the
small "BREW" switch until you hear the solenoid click on-and-off three times (approximately 10 seconds), then
release the small "BREW" switch and allow the cycle to fi nish.
NOTE: Repeat the steps above to set the large batch by using the large brew switch as desired.
OPTIONAL PULSE BREW SET-UP:
NOTE: Set small and large batches separately. Brewer has 4 preset pulse brew routines to choose from.
Factory default is 1. With 4 being the maximum time.
With the machine off, press the small or large switch for 10 seconds. Red LED will fl ash to indicate current setting
( 1 – 4 ). Press same switch the number of times ( 1 – 4 ) for the desired setting. If the switch is pressed more
than 4 times, the setting will remain at 4. After 5 seconds the red Led will resume fl ashing the selected number.
When no switches are pressed for 30 seconds, the mode will exit. Or the mode may be exited by pressing the
"ENABLE BREW ON/OFF" switch. Repeat above procedure with the other brew switch.
Restore Factory Defaults:
Press the "ENABLE BREW ON/OFF" switch while applying AC power. Continue pressing the "ENABLE BREW ON/
OFF" switch for 10 seconds. During that 10 seconds, the red LED will be on steady. After 10 seconds the green
LED will begin fl ashing rapidly for 5 seconds. During that 5 seconds, release and again momentarily press the
"ENABLE BREW ON/OFF" switch again to restore default settings. The Led will alternate rapidly Red and Green
for a few seconds indicating the restore has been accomplished.

DELIMING
Bunn-O-Matic recommends deliming your coffee brewer periodically. The actual frequency of deliming depends on the mineral content of the water you use. NOTE: In hard water areas, this may need to be done daily.

Follow these simple steps:
1. Unplug the brewer and
let it cool down before
proceeding.
2. Remove the brew funnel.
3. Remove the sprayhead by
turning it to the left with
your fi ngertips and set it
aside.
4. 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 fi ve
or six times. Remove the
spring.
5. Check the holes in the
sprayhead. If plugged by
lime, they may be cleared
using a toothpick. Rinse
the sprayhead with water
before reinstalling it.
6. Reinstall the sprayhead
by turning it to the right.
7. Plug in the brewer and
allow the water to reheat
before using.
Remove sprayhead by
turning counterclockwise
