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 keyholes in the drip tray bracket over the lower two screws in the panel below the hopper access door; push down gently and tighten the screws.
4. Place the set of keyholes in the splash panel over the upper two screws and position so the screws are between the holes.

ELECTRICAL REQUIREMENTS

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 corset. The mating connector must be a NEMA 5-15R.
To access the terminal block for high voltage models without a corset, remove the left side panel.

Electrical Hook-Up

220-240V AC
single-phase models

Note: This electrical service consists of 2 current carrying conductors (L1 and L2) and a separate conductor for the earth ground.
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. Place the ON/OFF/NIGHT switch in the “ON” 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 or hot water system with operating pressure between 20 and 90 psi (0.138 to 0.620 mPa) 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 (0.690 mPa) to reduce it to 50 psi (0.345 mPa). 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 FDA-approved flexible beverage tubing, such as reinforced braided polyethylene or silicone, before the dispenser, will facilitate movement to clean the countertop. 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.

NOTE – If a backflow preventer is required by code, a shock arrestor should be installed between the backflow preventer and dispenser.
Installing the shock arrestor as close to the dispenser as possible will provide the best results.
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.

PLUMBING HOOK-UP

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.

INITIAL FILL & HEAT

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 ten minutes.
3. When the tank is full of water, open the front door and place the ON/OFF/NIGHT switch in the “ON” (upper) position. A tank full of cold water will take approximately eighty minutes for the water to heat on 120-volt versions and forty minutes on 120/240 volt and 220-240 volt versions.
4. Fill the hopper(s) 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 adjusts 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 10 minutes, a refill error occurs. When a refill error occurs, the refill solenoid is de-energized. Once the cause of the refill  error has been investigated and cured, the system can be reset by either disconnecting (for at least 5 seconds) and then reconnecting the power to the machine,  or by entering one of the program modes (see Programming Modes.)

RINSE TIMER
The dispenser is shipped from the factory with the rinse timer disabled. To enable the rinse timer, refer to Programming the Dispenser and select yes in the  “Rinse Alarm ?” screen; set timer to the desired time and exit the programming mode.
When enabled, the rinse timer automatically keeps track of the time since the dispenser was the last run through a rinse sequence. If the dispenser detects that a  rinse sequence has not been run for the desired time, a message will appear on the LCD display. If the Lockout is set, after an additional 4 hours, a rinse cycle has still not been run, the LCD display will display a message, and the hopper drives will be disabled until a rinse sequence has been run.

RUNNING A RINSE SEQUENCE

1. Place the Normal/Program/Rinse switch (page 10) in the “rinse” position.
2. Sequentially at each position, press all of the dispense switches. The dispenser will run for 10 seconds with the hopper(s) disabled.
3. As each position is rinsed, the LCD display will show which position is being rinsed and count down from 10 seconds.
4. After all positions have been rinsed, return the Normal/Program/Rinse switch to the “Normal” position.

DISPENSER USE – Self Serve

1. Simply place a cup on the drip tray beneath the desired dispensing tip.
2. Press the button to froth and dispense the beverage.
3. Release the button when the cup is approximately 3/4 full and allow the mixing chamber to drain.

Note – The mixing chamber must drain at the end of each dispense.

DISPENSER USE – Portion Control

1. Simply place a cap on the drip tray beneath the desired dispensing tip.
2. Select the appropriate button for the cup size under the dispense tip, press momentarily, then release.
3. Let the mixing chamber completely drain before removing the cup.

HOT WATER DISPENSE – IMIX-5 only

1. Simply place a cap on the drip tray beneath the hot water dispense arrow.
2. Press the button to dispense hot water.
3. Release the button when the desired amount is reached.

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.
NOTE: Replacement parts or service caused by failure to perform required maintenance is not covered by warranty.

CLEANING

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. 

HOPPER DISPENSE RATE OF PRODUCT
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 rate 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, by following the procedures described in Programming Modes.

HOPPER LEVEL SENSOR CALIBRATION

The dispenser is equipped with sensors to detect a low level in each hopper. When low powder lockout is enabled, dispensing will be disabled when a low power condition is detected in a hopper. The LCD screen on the door will also display a low-level condition.

The dispenser is shipped from the factory with the low-level powder lock disabled. To enable the lock, place the “NORMAUPROGRAM/RINSE” switch (page 10) in the “PROGRAM” position. Press button A (page 10) below the BUNN logo on the front of the door. Continue to press this button until the “LOCKS/DISABLES?” menu is reached. Press button B (page 101 for “YES”, then press it again in the “LOW POWDER LOCK?” menu. The low powder lockout is now enabled. Press button C (page 10) to exit the program menus, then return the “NORMAUPROGRAM/RINSE” button to the “NORMAL” position. To disable the low powder lockout, repeat the process, and press button D (page 10) for “NO”, in the “LOW POWDER LOCK” menu.

The low-level sensors are factory calibrated for most products. If calibration is required for proper opera­tion, the sensors can be recalibrated to the current product.
The hopper must be at least half full of product for calibration. Place the “NORMAUPROGRAM/RINSE” switch in the “PROGRAM” position. Using button A (page 10), forward until the “CALIBRATION?” menu is reached. Press button B (page 10) for “YES”, then press button A (page 10) until “CAL HOPPER 1?” screen is reached. Continue to press button A until the hopper to be calibrated is reached.
To calibrate the hopper, press button B (page 10) to indicate “YES” in the “CAL HOPPER#? screen. The screen will then ask you if the hopper is full. Press the button again to indicate “YES”. The calibration will then take a few moments, then the screen will display “POWDER LEVEL RESET COMPLETE”. The next hopper may be calibrated by moving forward in the menu, or press button C (page 10) to exit.

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 the front door and place the ON/OFF/NIGHT switch in the “OFF” (center) position and let the water in the tank cool before draining.
3. Shut off and disconnect the incoming water supply.
4. Remove the drip tray and access panels below the door.
