ELECTRICAL REQUIREMENTS

WARNING -

The brewer must be disconnected from the power source until speciﬁ ed in Initial Set-Up. Refer to Data Plate on the Brewer, and local/national electrical codes to determine circuit requirements.

ELECTRICAL HOOK-UP (All Models) CAUTION – Improper electrical installation will damage electronic components.

1. An electrician must provide electrical service.

2. Determine the available on-site electrical service.

3. Select the desired unit voltage based on the available on-site electrical service.

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

5. Remove the front access panel beneath the sprayhead to gain access to the terminal block.

6. Feed the supply leads through the rear of the brewer.

7. Using the above diagrams, connect the desired electrical service to the ﬁ eld wiring terminal block.

8. If wiring the machine for operation on 120/208 or 120/240 volts with a Power Supply Cord, the Power Supply Cord must be UL Listed Flexible Cord Type SO, SJO, SJTO, HSJO or SJOW, No. 12 AWG, 4 Conductor, Rated 90° C. Attachment Plug Cap must be UL Listed, NEMA 14-20P or L14-20P Conﬁ guration, Rated 125/250V, 20 AMPS. The Power Supply Cord must be at least 3 feet long and maximum 6 feet long (measured from Strain Relief to end of the Attachment Plug Cap).

9. Before proceeding, verify the voltage at the ﬁ eld wiring terminal block.

10. Set voltage switch to the appropriate position and replace the access panel. (DV Models Only)

11. 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.

Note: This electrical service require 3

current carrying conductors (Neutral, L1 and L2) and a separate conductor for earth ground

Twins

All Twins are 120/208 & 120/240V AC

Single phase unless otherwise noted.

Note: Power cord must be

connected to center terminal block on all Twins unless otherwise noted.

PLUMBING REQUIREMENTS

These brewers must be connected to a cold water system with operating pressure between 20 and 90 psi (138 and 620 kPa) 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 (620 kPa) to reduce it to 50 psi (345 kPa). The water inlet ﬁ tting is 1⁄4" ﬂ are.

NOTE - Bunn-O-Matic recommends 1⁄4" copper tubing for installations of less than 25 feet and 3⁄8" for more than 25 f eet from the 1⁄2" water supply line. A tight coil of copper tubing in the water line will facilitate moving the bre wer to clean the counter top . 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 Ser vice Sanitation Manual of the Food and Drug Administration (FDA). For models installed outside the U.S.A., comply with the applicable Plumbing /Sanitation Code.

1. Flush the water line and securely attach it to the inlet ﬁ tting at the rear of the brewer.

2. Turn on the water supply.

INITIAL SET-UP

1. Insert an empty funnel into the funnel rails.

2. Place an empty server under the funnel.

3. Connect the brewer to the power source.

4. Turn on the main ON/OFF switch located on the

left side of brewer (If equipped).

5. Press and release the "ENABLE BREW ON/OFF"

switch. (Indicator m ust be lit!). Water will ﬂ ow into the tank and stop when the tank is ﬁ lled to its capacity . Displa y will show "PLEASE W AIT...T ANK FILLING" until tank is ﬁ lled with water.

6. Wait approximately twenty minutes for the water

in the tank to heat to the proper temperature. Display will show "READY TO BREW...W ATER TEMP: 200°" when tank is at operating temper ature. Some water will drip from the funnel during this time; this is due to e xpansion and should not occur thereafter.

7. Place a small container beneath the faucet and

open the faucet handle. Release it when you hear the tank reﬁ lling.

8. Water volumes and ﬂ ow settings have been preset

at the factory. Refer to adjustments for the Set Brew Volumes section of this manual should the volume need to be increased or decreased.

9. The brewer is now ready for use in accordance

with the instructions for Coffee Brewing.

10. Repeat steps 5-9 for remaining side on Twins.

If setting up new brewer in high mineral locations, refer to programming (Enable Brew Logic). Pertains to units with software version 1.06 & up.

Brew water temperature is factory set at 200o F (93.3o C) Areas of high altitude will require lowering this temperature to prevent boiling. This chart should be used as a guide when readjusting the brew water temperature.

OPERATING CONTROLS

(A) ENABLE BREW ON/OFF SWITCH

Pressing the "ENABLE BREW ON/OFF" switch (indicator on) supplies power to the brew station w armer, enab les the brew circuit, and energizes the tank reﬁ ll circuit. Pressing the switch again (indicator off) stops tank reﬁ lling and brewing and de-energizes the brew station warmer . 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 – Hot water will be availab le at the f aucet in a limited

amount when the "ENABLE BREW ON/OFF" switch is in the "OFF" position because the tank will not reﬁ ll.

(B) BREW SWITCH

Momentarily pressing and releasing the switch starts a brew cycle when the "ENABLE BREW

ON/OFF" indicator is on.

Pressing any additional warmer switch so that the indicator is on, supplies power to the associated warmer. NOTE: APS & TC models have no warmers.

COFFEE BREWING

1. Begin each brew cycle with a clean empty brew funnel.

2. Insert a BUNN ﬁ lter into the funnel.

3. Pour (or grind) fresh coffee into the ﬁ lter and level the bed of grounds by gently shaking.

4. Slide the funnel into the funnel rails until it stops.

5. Place an empty server under the funnel.

6. V erify that the "ENABLE BREW ON/OFF" indicator is on.

7. Momentarily press and release the "BREW" switch. The display will read "NO W BREWING", and show the time remaining in the brew cycle.

8. Following the brew , the displa y reads "DRIPPING" which shows the time remaining until the coffee no longer drips from the funnel tip.

9. After the coffee ﬁ nishes dripping from the funnel tip, carefully remove the brew funnel and discard the grounds and ﬁ lter.

NOTE: Some models are equipped with a backup pour in feature, in case the plumbed water supply is disrupted. In this e v ent, disregard steps 7-8, and pour in 64 ounces of fresh water.

CLEANING

1. The use of a damp cloth rinsed in any mild, nonabrasive, liquid detergent is recommended for cleaning all surfaces on Bunn-O-Matic equipment.

2. Check and clean the spra yhead. The sprayhead holes must alw ays remain open. Insert the short end of the sprayhead cleaning tool into each of the ﬁ ve water outlets of the plastic sprayhead to remove any mineral deposits (Refer to Fig 1)

3. Insert the long end of spra yhead cleaning tool into the spra yhead ﬁ tting, and rotate sev eral times to remove any mineral deposits from the ﬁ tting (Refer to Fig 2).

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.

NOTE: In the event that the "Brew Logic" circuit activates (compensating for high lime build up), it will temporarily disable the "Recovery Booster" and "Pulse Brewing" systems until the unit has been de-limed. Refer to the Troubleshooting section for more details.

FIGURE 1 FIGURE 2

1. Loosen screws that secure the front access panel. Remove the panel.

2. Unfasten the hose clamp at the end of the drain hose. Remove the plug.

3. Place the end of the drain hose in a container that has a minimum capacity of 200 oz (5.9 L).

4. Release the white clamp to drain water from the tank.

5. When tank is empty, close the white clamp, replace the plug, and tighten the clamp at the end

of the drain hose. (Repeat steps 2-5 for remaining side on Twins)

6. Replace the front panel and tighten screws.
