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.

REPLACING THE PUMP TUBING

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 inside the Cabinet door.

Note: To avoid concentrate spills, rinse the pump tubing with warm tap water prior to removing the tubes, (Refer to steps 1 - 4 of the Weekly Sanitizing instructions).

1.Loosen the thumbscrew (Fig 1) securing the tubing retainer plate to the pump body and set the retainer plate aside.

2.Depress the tension screw and remove it from the notch in the pump body, releasing the spring tension on the pump band (Fig 2).

3.Gently pull the pump tube from around the pump rotor (Fig 3).

4.Inspect the pump bands, rollers and housing for contamination or signs of wear. Clean or replace worn parts if neces- sary.

5.Apply lubricant (BUNN-O-MATIC part no. M2531.0001) to the middle section of the new pump tubing (Fig 4).

6.Carefully wrap the new tubing around the rotor, making sure that the elbow and clamps end up on the front side of the pump body (Fig 5).

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

8.Install the free end of the tube over the inlet port of the mix chamber on that side of the cabinet (Fig. 5).

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

9.Open the product container and insert the stainless steel drawtube into the container (Fig 6).
