Frequently Asked Questions - iMIX-5 Bunn

How do I clean my Bunn iMIX-5 coffee maker?

Daily rinsing of the brew basket and decanters is recommended. Weekly, run a cleaning cycle using Bunn Cleaner or a descaling solution to remove mineral deposits.

What type of water should I use?

Use filtered or softened water to minimize scale buildup. Hard water may require more frequent descaling.

How do I set the programmable timer?

Press the PROG button, then use the HOUR and MINUTE buttons to set the desired start time. Press ENTER to confirm.

My brewer is not heating the water. What should I check?

Ensure the power cord is plugged in and the circuit breaker is not tripped. If the issue persists, check the thermal fuse or contact service.

Can I use pre-ground coffee or must I grind beans?

The iMIX-5 is designed for pre-ground coffee. Use a medium grind for best extraction.

What is the warranty on this machine?

Bunn offers a 3-year warranty on parts and labor for commercial use. Contact your dealer for details.

How do I replace the spray head?

Turn off and unplug the brewer. Remove the brew basket, then unscrew the spray head with a Phillips screwdriver. Install the new head and reassemble.

My coffee tastes bitter. What could be wrong?

Bitter coffee often indicates over-extraction. Use a coarser grind or reduce brew time. Also check water temperature should be 195-205°F.

How often should I descale the brewer?

Descaling frequency depends on water hardness. Typically every 3 months or when you notice slow brewing or error codes.

Where can I find replacement parts?

Original Bunn parts are available at authorized dealers and online retailers. Use the model number iMIX-5 for correct parts.

PLUMBING REQUIREMENTS

This dispenser must be connected to a cold water system with operating pressure between 20 and 90 psi 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 to reduce it to 50 psi. 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 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 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 230 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 adjust the tank temperature to the powder product manufacturer's recommended temperature for the hot powder product being used.

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 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.

NOTA:

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 powder condition is detected in a hopper. The LCD screen on the door will also display a low level condition.

The despenser is shipped from the factory with the low level powder lock disabled. To enable the lock, place the “NORMAL/PROGRAM/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 10) 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 “NORMAL/PROGRAM/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 “NORMAL/PROGRAM/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.
