 After cutting the tube, be sure to remove all burrs and finish tubing ends to the
correct surface. (The same must be done for branch tubes (purchased separately).)
 When bending tubes, be sure the bend radius is at least 4 times the outer diameter
of the tube.
 When cutting or bending tubes, be careful not to cause any pinching or blockage of
the tube.
• Prevent foreign substances such as dirt or water from entering the tube by
sealing the end of the tubes with either a cap or with tape.
Otherwise, this can damage the devices and result in malfunction.
