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 1⁄2” 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 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. 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.
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 (Early Models)
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.
PLUMBING HOOk-UP (Late Models)
1. Flush the water line and securely attach it to the elbow fitting on the bottom of the dispenser.
2. Turn-on the water supply.
NOTE - Water pipe connections and fixtures directly connected to a potable water supply shall be sized, installed
and maintained in accordance with federal, state and local codes.
PRESET TANk TEMPERATURE
Tank temperatures have been preset at the factory to 180°F (82°C). Bunn recommends that to provide the best
quality beverage, the installer adjust the tank temperature to the powder product manufacturer’s recommended
temperature for the hot powder product being used.
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, 120/240 volt versions and 220-240 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 recon-
necting 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.

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 approxi-
mately 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 approxi-
mately 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.
6. Insert a tube to the bottom of the tank and syphon ALL of the water out.
NOTE - The dispenser must be refilled using the INITIAL FILL & HEAT steps before reconnecting to the power
source.
