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.

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

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.

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.

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.

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.

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 (whipper models only).

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

HOPPER THROW TEST

The hopper throw rate, grams per second (g/s) or ounces per second (oz./s), can be checked by automatically running the hopper motor for 10 seconds.

1.Remove the steam collector and mixing chamber (whipper models only) from under the hopper to be checked.

2.Position a small cup under the hopper outlet.

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

4.Press and hold the dispense switch of the appropriate chamber for 5 seconds. The hopper motor will run for 10 seconds at the programmed speed.

5.Remove the cup and weigh the dispensed product. To calculate the throw rate (g/s or oz./s), divide the total weight of the dispensed product by 10.

6.Replace the mixing chamber and steam collector, and return the rinse/run switch to the run position.

PREVENTIVE MAINTENANCE

Bunn-O-Matic® Corporation recommends that preventive maintenance be performed at regular intervals. Maintenance should be performed by a qualified service technician. For Technical Service, contact Bunn-O-Matic® Corporation at 1-800-286-6070.

ADJUSTMENTS

The beverage solenoid is preset to dispense approximately 9/10 ounce per second (26 mL/sec) or approximately 4/10 ounce per second (12 mL/sec) on non whipper models (oatmeal, etc.). 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 and can be individually programmed per hopper, 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.
