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

1-800-286-6070.

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. Bunn-O-Matic recommends replacing the Pump Tubing a minimum of once every 6 months or

sooner if warranted.

Refer to the Tube Replacement Instruction on the Cabinet door for details.

1. 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.

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

aside.

3. Depress the tension screw and remove it from the notch in the pump housing, releasing the spring tension

on the pump band.

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

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

6. Apply lubricant (BUNN-O-MATIC part number M2548.1000) to the new pump tubing's rotor side.

7. Insert the tube onto the mix chamber port, then wrap the new tubing around the pump rotor, making sure

that the elbow and clamps end up on the bottom side of the pump housing.

8. Depress the tension screw and insert it in the notch in the pump body, reapplying spring tension on the pump

band.

9. Replace the tubing retainer plate and tighten the thumbscrew.

10. Repeat steps 1 through 9 for the other pump.
