INITIAL SET-UP

1.Locate the drip tray assembly beneath the dispenser nested in the packing material.

2.Remove the drip tray and the drip tray cover and set them aside.

3.Remove the water strainer assembly from the drip tray and set it aside.

4.Remove the four legs from the packaging material, apply non-skid pads to the bottom of the legs and securely install the legs in the dispenser base.

ELECTRICAL REQUIREMENTS

CAUTION - The dispenser must be disconnected from the power source until specified in Initial Set-Up.

The 120 volt version of this dispenser has an attached cordset and requires 2-wire, grounded service rated 120 volts ac, 15 amp, single phase, 60 Hz. The mating connector must be a NEMA 5-15R.

The 120/208 and the 120/240 versions of this dispenser has an attched cordset. The mating connector must be a NEMA 14-20R.

(Refer to the dispenser’s dataplate for exact voltage requirement.)

ELECTRICAL HOOK-UP

CAUTION – Improper electrical installation will damage electronic components.

1.An electrician must provide electrical service as specified.

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

3.Open the front door of the dispenser and place the heater switch in the “OFF” (upper position).

4.Connect the dispenser to the power source.

5.If plumbing is to be hooked-up later be sure the dispenser is disconnected from the power source. If plumbing has been hooked-up, the dispenser is ready for Initial Fill & Heat.

PLUMBING REQUIREMENTS

This dispenser must be connected to a COLD WATER system with operating pressure between 20 and 90 psi (138 and 620 kPa) from a 12" or larger supply line. A shut-off valve should be installed in the line before the dispenser. 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 14" flare.

NOTE - Bunn-O-Matic recommends 14" copper tubing for installations of less than 25 feet and 38" for more than 25 feet from the 12" water supply line. At least 18 inches of an FDA approved flexible beverage tubing, such as reinforced braided polyethylene or silicone, before the brewer will facilitate movement 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). For models installed outside the U.S.A., you must comply to the applicable Plumbing/Sanitation Code for your area.

PLUMBING HOOK-UP

1.Securely attach the short piece of tubing on the water strainer assembly to the inlet fitting on the bottom of the dispenser.

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

3.Turn-on the water supply.

4

29112 011906

 

INITIAL FILL & HEAT

CAUTION - The dispenser must be disconnected from the power source throughout the initial set-up, except when specified in the instructions.

1.Turn-on the water supply and connect the dispenser to the power source.

2.Water will automatically flow into the tank to the proper level and then shut-off. This will take less than five minutes.

3.When the tank is full of water, open the front door and place the heater switch in the “ON” (lower) position. A tank full of cold water will take approximately forty minutes for the water to heat on 120 volt versions or twenty minutes for 120/208 volt versions and 120/240 volt versions.

During this waiting period, complete these dispenser set-up steps:

a.Place the drip tray in front of the dispenser. Set the drip tray cover in place.

b.Place a set of keyholes in the cup locator plate over the screws beneath the hopper access door and push down gently.

c.Fill the hopper with the dry product to be dispensed.

LIQUID LEVEL CONTROL

The system automatically maintains the hot water tank’s level by energizing the refill solenoid when the water level drops below the liquid level probe. If the system for the FMD-2 only has not successfully refilled in 7 1/2 minutes, a refill error occurs.

When a refill error occurs, the refill solenoid is de-energized and the rinse L.E.D. will flash about once every 5 seconds.

Once the cause of the refill error has been investigated (see the troubleshooting guide in the Operating and Service Manual) and cured, the system can be reset by disconnecting (for at least 5 seconds) and then reconnecting the power to the machine.

RINSE TIMER (FMD-2 ONLY)

The dispenser is shipped from the factory with the rinse timer disabled. To enable the rinse timer, remove power from the dispenser, remove the lower access panel, and remove the jumper from J1 of the control board. Replace the lower access panel, and return power to the dispenser.

When enabled, the rinse timer automatically keeps track of the time since the dispenser was last run through a rinse sequence. If the dispenser detects that a rinse sequence has not been run for 8 hours, the rinse L.E.D. will flash continually. If, after an additional 4 hours (12 hours total), a rinse sequence has still not been run, the rinse L.E.D. will light continuously, and the hopper drives will be disabled until a rinse sequence has been run.

RUNNING A RINSE SEQUENCE

1.Place the rinse/run switch in the rinse position.

2.Sequentially, or simultaneously, at each of the two positions (FMD-2 only) dispense for at least 10 seconds.

3.After the rinse L.E.D. has extinguished, the rinse timer is reset (FMD-2 only).

4.Return the rinse/run switch to the run position.

DISPENSER USE

1.Simply place a cup on the drip tray beneath the dispensing tip.

2.Press the button to froth and dispense the beverage.

3.Release the button when the cup is approximately 2/3 full and allow the mixing chamber to drain.

NOTE - The mixing chamber must drain at the end of each dispense.

COLD BEVERAGE SET-UP (OPTIONAL FMD-2 ONLY)

Cold beverages may be dispensed from the left dispense position as follows:

1.Disconnect the dispenser from the power source.

2.Remove the lower front access panel.

3.Locate the Hot/Cold jumper connection near the whipper panel in the main wiring harness.

4.Remove the Hot jumper connection (red jumper plug) from the main wiring harness and connect the Cold jumper connection (blue jumper plug) to the main harness.

5.Replace the lower front access panel and reconnect the dispenser to the power source.

CLEANING

Refer to the decal on the rear of the dispenser door for cleaning recommendations and proccedures.

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

ADJUSTMENTS

The beverage solenoid is preset to dispense approximately one ounce per second. This amount can be adjusted:

1.Disconnect the dispenser from the power source.

2.Remove product hopper(s).

3.Remove the hole plug(s) in the auger motor mounting panel.

4.Rotate the control at the base of the solenoid clockwise to decrease or counterclockwise to increase the amount of water.

5.Reinstall plug(s) and hopper(s).

HOPPER MOTOR SPEED ADJUSTMENT (FMD-1)

The hopper dispense rate is preset at the factory. With 8 tooth gear and auger wire the preset dispense rate is approximately 3 to 5 grams per second. With 12 tooth gear and auger wire the preset dispense rate is approximately 5 to 7 grams per second. The hopper dispense rate can be adjusted to a range of dispense rates from approximately 1.5 to 12 grams per second, as follows:

1.Set the tank heater switch to the off position.

2.Open the top front cover of the dispenser and remove the two screws securing the top cover.

3.Remove the top cover assembly and set it aside.

4.Locate the motor speed adjuster (leftmost) on the dispenser cabinet top cross member.

5.Using extreme care not to touch the live terminals of the tank heater, adjust the motor speed by rotating the motor speed adjuster to the desired point, ranging from minimum (full counterclockwise) to maximum (full clockwise.)

6.After the motor adjustment is complete, replace the top cover assembly, securing it with the two screws, and return the tank heater switch to the on position.

HOPPER MOTOR SPEED PROGRAMING (FMD-2)

The hopper dispense rate is preset at the factory. With 22 tooth gear and auger wire the preset dispense rate is approximately 3 to 5 grams per second. With 32 tooth gear and auger wire the preset dispense rate is approximately 5 to 7 grams per second. The hopper dispense rate can be adjusted to a range of dispense rates from approximately 1.5 to 12 grams per second, as follows:

1.Place the rinse/run switch in the center (program) position.

2.Place the increase/decrease switch in the desired (increase or decrease) position.

3.Press and release the dispense switch for the chamber you wish to adjust. Each time the dispense switch is pressed, the rinse L.E.D. will flash, and the motor speed for that hopper will be increased/decreased by approximately 2 1/2%.

4.Return the rinse/run switch to the run position after hopper motor speed adjustments are complete.

DRAINING THE HOT WATER TANK

CAUTION - The dispenser must be disconnected from the power source throughout these steps.

1.Disconnect the dispenser from the power source.

2.Open front door and place tank heater switch in the “OFF” (upper) position.

3.Shut-off and disconnect the incoming water supply.

4.Remove the top panel.

5.Gently remove one of the grommets from the tank lid.

TROUBLESHOOTING

A troubleshooting guide is provided to suggest probable causes and remedies for the most likely problems encountered. If the problem remains after exhausting the troubleshooting steps, contact the Bunn-O-Matic Technical Service Department.

Inspection, testing, and repair of electrical equipment should be performed only by qualified service personnel.

All electronic components have 120 volt ac and low voltage dc potential on their terminals. Shorting of terminals or the application of external voltages may result in board failure.

Intermittent operation of electronic circuit boards is unlikely. Board failure will normally be permanent. If an intermittent condition is encountered, the cause will likely be a switch contact or a loose connection at a terminal or crimp.

Solenoid removal requires interrupting the water supply to the valve. Damage may result if solenoids are energized for more than ten minutes without a supply of water.

The use of two wrenches is recommended whenever plumbing fittings are tightened or loosened. This will help to avoid twists and kinks in the tubing.

Make certain that all plumbing connections are sealed and electrical connections tight and isolated.

This unit is heated at all times. Keep away from combustibles.

WARNING – • Exercise extreme caution when servicing electrical equipment.

Unplug the dispenser when servicing, except when electrical tests are specified.

Follow recommended service procedures

Replace all protective shields or safety notices
