Bunn LCA-2 IC Manual De Propietario

19

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 

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.

Note: Replacement Tube/Adapter Kits can be purchased from BUNN-O-MATIC.
