INSTALLATION & OPERATING INSTRUCTIONS

INTRODUCTION

This equipment will grind a preselected amount of whole bean coffee into the brew funnel and automatically brew a
half-gallon batch of coffee into an awaiting decanter. All functions of the grinder and brewer are independently adjustable.
It includes a hot water faucet for allied beverage use. It is only for indoor use on a sturdy, level counter or shelf.
The grind is preset at the factory to drip specifications as set forth by the United States Department of Commerce and

ELECTRICAL REQUIREMENTS

CAUTION - Do not connect to the power source until specified in Initial Set-Up.

This equipment requires either 2-wire, grounded service rated 120 volts ac or 3-wire, grounded service rated 120/

208 or 120/240 volts ac, 20 amp, single phase, 60 Hz. Refer to the product data plates on the brewer and grinder for
actual voltage of your particular model.

CAUTION – Improper electrical installation will damage electronic components.

1. An electrician must provide electrical service as specified.

2. Remove the brewer top lid held in place with one screw. Lift the front of the lid slightly and push it back.

3. Remove the restraining device from the swing-away coffee chute. it will swing to a vertical position when freed.

4. (1-hopper grinder) Remove the screw below the grinder's front decal. Tilt the grinder back on the top lid and set
the screw aside for later installation.
(2-hopper grinder) Remove the front inspection panel on the grinder. Set it aside for later installation.

5. Set the grinder on top of the brewer sliding it to interconnect the tab with its mating slot.

6. Plug the grinder's polarized six-pin electrical connector into its mate at the top of the brewer.

7. Install the screw to secure the front of the grinder to the brewer.

8. (1-hopper grinder) Tilt the grinder forward over the hood front.

NOTE – The swing away coffee chute mechanism must not get jammed. It must be in front of the movable sprayhead
mechanism. Move the sprayhead mechanism out of the way if necessary by pushing the threaded rod to either side
of the hood and then pushing the bracket until it is as far back as possible.

8. Place the switch on the rear of brewer in the “OFF” (lower) position.

9. Remove the front panel of the brewer. Set it aside for later installation.

10. Place the heater switch at the bottom of the Digital Brewer Control (DBC) , the box on the top of the component
mounting bracket, in the “OFF” (left) position.

11. Feed the cord through the strain relief at the rear of the brewer and connect it to the terminal block.

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

13. Connect the brewer to the power source, verify the voltage at the terminal block and reinstall the brewer front panel.

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.

14. 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.

PLUMBING REQUIREMENTS

This brewer must be connected to a cold water system with operating pressure between 30 and 90 psi 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 to reduce it to 50 psi. 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 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 as indicated on the illustration adjacent to the water inlet fittings.

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

3. Turn on the water supply.

INITIAL SET-UP

CAUTION - The Combo® must be disconnected from the power source throughout the initial set-up, except when

specified in the instructions.

Brewer

1. Place the switch at rear of the Combo® in the “ON” (upper) position

2. Insert an empty funnel into the funnel rails.

3. Hold an empty decanter beneath the hot water faucet on the front of the Combo®. Hold the faucet open until a steady
stream of water flows from it.

4. Empty the decanter and place it on the warmer.

5. Place the Selector switch (center) in the lower “BREW ONLY” position.

6. Connect the Combo® to the power source. Place the On/Off switch in the lighted “ON” position and momentarily
press the start switch. Water will flow into the tank.

7. When the flow of water into the tank cannot be heard, remove and reinsert the empty brew funnel. Press the start
switch again to initiate a second cycle.

8. When the flow of water into the tank cannot be heard, remove and reinsert the empty brew funnel. Press the start
switch again to initiate a third cycle. During this cycle, the tank will fill to its capacity and the excess will flow from
the funnel into the decanter. Place the On/Off switch in the “OFF” position and empty the decanter when the flow
of water from the funnel stops.

9. Disconnect the Combo® from the power source, remove the brewer front panel, and place the heater switch on the
Digital Brewer Control (DBC) , the box on the top of the component mounting bracket, in the “ON” position.

10. Connect the Combo® 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.

11. Place the On/Off switch in the lighted “ON” position, remove and reinsert the empty brew funnel, and momentarily
press the start switch. Place the On/Off switch in the “OFF” position and empty the decanter when the flow of water
from the funnel stops.

12. Allow the water in the tank to heat to the proper temperature.
