Page 4 40410 030714

PLUMBING REQUIREMENTS

These brewers must be connected to a cold water system with operating pressure between 20 and 90 psi

(0.138 and 0.620 MPa) from a 1 ⁄

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 (0.620 MPa) to reduce it to 50 psi

(0.345 MPa). The water inlet fitting is 1 ⁄

4

" flare. Bunn-O-Matic does not recommend the use of a reverse-osmosis or deionized water supply to this equipment.

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 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.

NOTE - If a backflow preventer is required by code, a shock arrestor should be installed between backflow preventer and brewer. Installing the shock arrestor as close to brewer as possible will provide best results.

As directed in the International Plumbing Code of the International Code Council and the Food Code Manual of the Food and Drug Administration (FDA), this equipment must be installed with adequate backflow prevention to comply with federal, state and local codes. For models installed outside the U.S.A., you must comply with the applicable Plumbing /Sanitation Code for your area.

Plumbing Hook-Up

1. Remove the shipping cap from the fitting on the rear of the brewer.

2. Securely attach adaptor elbow assembly to the fitting at the rear of the brewer.

3. Flush the water line and securely attach it to the adaptor elbow.

4. 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. Insert an empty funnel into the funnel rails. (FIG 6A)

2. Place an empty server (customer supplied) 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 6B)

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 flow into the tank and stop when the tank is filled 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 flow 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 refill circuit. Pressing the switch again (indicator off) stops tank refilling and brewing. Stopping a brew cycle after it has been started will not stop the flow 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 refill 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 refill. 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

Steady green - ready to brew.

Steady red - tank is heating up.

PROGRAMMING - SILVER SERIES

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 flashes 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 finish.

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 finish.

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 flash 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 flashing 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 flashing 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.

Note: The Restore process cannot be done when Dip Switch # 1 is On (Program Lockout)

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.

It will help prevent liming problems in the brewer and takes less than a minute.

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 fingertips 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 five 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

CLEANING OPTIONAL LARGE SPRAYHEAD

1. Remove the brew funnel.

2. Remove the sprayhead by turning it counterclockwise with your fingertips.

3. Disassemble sprayhead by removing rubber gasket.
