Replacing The Pump Tubing - Bunn SLCC-6 Installation & Operating Manual

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 tube 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 thumbscrews securing the tubing retainer plates to the pump bodies and set the retainer plates
aside.
2. Depress the tension screws and remove them from the notch in the pump body, releasing the spring tension
