INITIAL SET-UP
1. Apply the four non-skid pads from the parts box to the bottom of the legs.
2. Remove the drip tray assembly, drip tray bracket, and splash panel assembly from the parts box.
3. Place a set of key holes in the drip tray bracket over the lower two screws in the panel below the hopper access door; push down gently and tighten screws.
4. Place the set of key holes in the splash panel over the upper two screws and position so the screws are
between the holes.
ELECTRICAL REQUIREMENTS
WARNING - If the power cord is ever damaged, it must be replaced by the manufacturer or its service agent with
a special cord available from the manufacturer or its service agent in order to avoid a hazard.
CAUTION - The dispenser must be disconnected from the power source until specified in Electrical Hook-Up.
The 120 volt version of this dispenser has an attached cordset.
Refer to the dispenser’s dataplate for exact voltage requirements.
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 100 psi
(138 and 690 kPa). This water source must be capable of producing a minimum flow rate of 4.5 fl. oz. (133.1
ml) per second. A shut-off valve should be installed in the line before the dispenser. Install a regulator in the
line when pressure is greater than 100 psi (690 kPa) to reduce it to 50 psi (345 kPa). The water inlet fitting is
.38" (9.52 mm) flare.
NOTE - At least 18 inches (457 mm) of an FDA approved flexible beverage tubing, such as reinforced braided
polyethylene or silicone, before the dispenser will facilitate movement to clean the countertop. It can be purchased
direct from Bunn-O-Matic (part number 32759.10--[See Illustrated Parts Catalog for complete part number]).
Bunn-O-Matic does not recommend the use of a saddle valve to install the dispenser. 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 with the applicable Plumbing/Sanitation Code for your area.
PLUMBING HOOK-UP
1. Flush the water line and securely attach it to the flare fitting on the bottom of the dispenser.
2. Turn-on the water supply.
36526 102705
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 eighty minutes (IMIX-5S) or forty-five minutes (IMIX-3S)
for the water to heat on 120 volt versions or forty minutes (IMIX-5S) or twenty-five minutes (IMIX-3S) 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 hoppers 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 has not successfully refilled in 15 minutes, a refill error
occurs. When a refill error occurs, the refill solenoid is de-energized and the left 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 placing the Rinse/Run switch in the
programming (center) position, momentarily.
RINSE TIMERS
The dispenser is shipped from the factory with the rinse timers disabled. To enable the rinse timers, remove
power from the dispenser, remove the lower access panel, and remove the jumper from J1 of the control boards.
Replace the lower access panel, and return power to the dispenser. When enabled, the rinse timers automatically keep 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 appropriate 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 appropriate rinse L.E.D. will
light continuously, and the appropriate 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 positions dispense for at least 10 seconds.
3. After the rinse L.E.D. has extinguished, the rinse timer is reset.
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 and dispense the beverage.
3. Release the button when the cup is approximately 3/4 full and allow the whipper chamber to drain.
NOTE - The whipper chamber must drain at the end of each dispense.
36526 040706
CLEANING
Refer to the decal on the rear of the dispenser door for cleaning recommendations and procedures.
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. Do NOT clean this equipment with a water jet device.
ADJUSTMENTS
The beverage solenoid is preset to dispense approximately 9/10 ounce per second (26 mL/sec). This amount
can be adjusted:
1. Disconnect the dispenser from the power source.
2. Remove the hoppers and the access panel behind the hoppers.
3. Rotate the control at the base of the solenoid clockwise to decrease or counterclockwise to increase the
amount of water.
4. Replace access panel when finished.
HOPPER MOTOR SPEED PROGRAMING
NOTE: The hopper dispense rates are preset at the factory. With 22 tooth gear and auger wire the preset dispense rate is approximately 3 to 5 grams per second. With 30 tooth gear and auger wire the preset dispense is
approximately 5 to 7 grams per second. The hopper dispense rates can be individually programmed 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. Hold the increase/decrease switch in the desired (increase or decrease) position.
3. While holding the increase/decrease switch, 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.
For IMIX-3S only:
5. Once any of the three hopper motors has been programmed to the desired speed, either or both of the other
hopper motors can be set to the same speed as follows:
a. Place the rinse/run switch in the center (program) position.
b. Press and hold the dispense switch that has been programmed for the correct speed.
NOTE: Care must be taken not to exceed 5 seconds, or a hopper throw test will occur.
c. Momentarily press the dispense switch for the hopper motor to be programmed. The rinse L.E.D. will light
for approximately 1 second, indicating that the speeds have been set equal.
d. Release both dispense switches.
e. Repeat step 5. b. through 5. d. for remaining hopper motor if desired.
f. 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. Place the tank heater switch in the “OFF” position.
3. Shut-off and disconnect the incoming water supply.
4. Remove the front, lower access panel.
5. Pull out drain tube to empty into a sink or a container with a minimum of 7-1/2 gallon (28.5 L) capacity.
6. Make sure drain clamp is closed. Then, remove drain plug.
7. Direct tube into sink or container and open drain clamp. Continue draining tank until ALL of the water is
out.
WARNING: Be very careful with the draining water because it can be very hot.
8. Close drain clamp, insert drain plug, place drain tube back into machine, and replace lower access panel.
NOTE - The dispenser must be refilled using the INITIAL FILL & HEAT steps before reconnecting to the power
source.
