9 <br />SELECTING THE CORRECT PUMP TUBING <br />There are two pump tube sizes available for use with this dispenser. To determine the correct tubing for your <br />application, first determine the dispenser flow rate you intend to use, refer to Setting Dispenser Flow Rate. Then <br />look up the recommended tube size for the mix ratio of your concentrate, refer to the Tube Selection Chart. <br />Examples: <br />1. For a Dispenser Flow Rate of 2.5 Oz./sec (74 mL/sec) and a Mix Ratio of 35:1 – use 3/16” I.D. Tubing. <br />2. For a Dispenser Flow Rate of 1.8 Oz./sec (53 mL/sec) and a Mix Ratio of 60:1 – use 1/8” I.D. Tubing. <br />Tube kits can be purchased from BUNN-O-MATIC. <br />Part # 34727.1000 for 3/16” I.D. Tubing or #34728.1000 for 1/8” I.D. Tubing. <br />INSTALLING THE PUMP TUBING (Refer to the Tubing Installation Instructions in side the cabinet door for <br />details.) <br />1. Loosen the thumbscrew securing the tubing retainer plate to the pump housing. Set it and the retainer plate <br />aside. <br />2.

Apply lubricant (BUNN-O-MATIC part number M2531.0001) to the new pump tubing. <br />4. Insert the tubing onto the mix chamber port and wrap the tubing around the pump rotor, making sure that <br />the elbow and clamps end up on the bottom side of the pump body. <br />5.
