Remove the lower splash guard assembly to access the digital programming module with LCD display

Open the cabinet door and set the Function Switch to the Rinse position. Close the door

Place a large container under the Left dispenser tip, then activate and hold the left dispenser

Dispense long enough to rinse all the concentrate out of the mix chamber and for the Conductance reading to stabilize and stop dropping

Record the nominal Conductance value displayed. This is the conductance reading of the water in your area

Repeat steps 3, 4 & 5 for the Right dispenser

Add 100 points to the larger of the Left or Right side Conductance value. This is the new Empty BIB threshold value for your dispenser

Enter this new value into the Empty BIB Alarm threshold

Locate the programming module and use the Arrow Down key to scroll through the LCD screen until 'CAL HOT WTR FLO?' appears

Did 'CAL HOT WTR FLO?' appear on the LCD screen?

Place a 64 Oz (2000 ml) graduated container under Hot Water Tip and press the hot water switch. The unit will dispense Hot Water for 20 seconds and then shut OFF automatically. Keep the graduated container under the dispense tip until all the water stops dripping

Measure the volume of water collected in the graduated container

Is the volume of water collected within the acceptable range of 32 - 38 Oz. (946 - 1124 ml)?

If the amount collected is not within the acceptable range, empty the container and repeat steps 2 & 3

If the amount collected is still not within range, inspect the hot water valve, tubing and fittings for lime, kinks, or other obstructions

Is the volume of water collected now within the acceptable range?

When satisfied with the volume of concentrate collected, press the Down Arrow Key

Select Prime on the Function Selector Switch and Run on the Mode Selector Switch

Remove the bag connector from the product box and disassemble or prop open the internal valve to allow free flow of product through the connector

Place the bag connector into a one-gallon (3.8 liter) container of warm soapy tap water 140°F (60°C)

Place an empty container under dispense tip and activate the corresponding Dispenser until the clean soapy water is dispensed from the dispense tip

Repeat steps 4 and 5 with warm tap water 140°F (60°C) to rinse the soapy water from the pump tubing

Continue dispensing until the water is clear, and no soapy water is being dispensed

Prepare 2.5 gallons (9.46L) of sanitizing solution by dissolving 1 packet of Kay 5 sanitizer into 2.5 gallons (9.46L) of 120°F (48.9°C) water to ensure 100 ppm of available chlorine

Again, repeat steps 4 and 5 with the sanitizing solution. Once sanitizing solution is visible, continue to dispense for 1 minute. Release handle and allow solution to sit for 5 minutes

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

Replace pump hoses every 6-Months or as needed

The pumps and tubing used in the dispenser are designed to give maximum performance and long life. However, the tubes are a wear item and must be replaced periodically. How long the tubes last is dependent on usage and properties of the concentrate. Excessive wear will reduce the output of the pumps resulting in a weak mixed beverage

Rinse the pump tubing with warm tap water (Refer to steps 1 - 5 of the Weekly Sanitizing instructions) prior to removing the tubes to avoid concentrate spills

Loosen the thumbscrew securing the tubing retainer plate to the pump housing. Set it and the retainer plate aside

Depress the tension screw and remove it from the notch in the pump housing, releasing the spring tension on the pump band

Open the compression band and gently pull the pump tube from around the pump's rotor

Inspect the pump bands for signs of wear. Replace if necessary

Apply lubricant (BUNN-O-MATIC part number M2531.0001) to the new pump tubing's rotor side.

Select Rinse on the Function Selector Switch and Run on the Mode Selector Switch

Place a 1/2 gal (2 liter) container under the appropriate dispense nozzle or nozzles

Activate the Dispenser of the appropriate side or sides for approximately twenty seconds or until the hot water is clear or has no concentrate coloring in it

Open the dispenser door, select Normal on the Function Selector Switch, and then close door

Note: To clear the 'Rinse' alarm, activate each dispenser until the flow stops automatically (approx. 20 seconds for each tip). The 'Rinse' alarm LED will turn off when the Rinse Procedure has been satisfied for both sides
