LOADING TUBING
CAUTION: Turn the drive off before removing or installing tubing. Fingers or loose clothing
could get caught in the drive mechanism.
Use Masterfl ex PERFECTPOSITION B/T Tubing. Th ese pumps are designed to use PERFECTPOSTION
B/T tubing sizes 87 and 91 only. Th e PERFECTPOSITION tubing retention marks (found on most of the
tubing formulations), indicate the best placement of the tubing within the pump head.
NOTE: Th e tubing sizes refer to the last two digits of the Masterfl ex PERFECTPOSITION B/T tubing
model numbers.
NOTE:
•
Check to confi rm that the rollers are clean and free of defects.
•
Tubing should be clean and routed so that the bend radii are at a minimum of four (4) times the outside
tube diameter and are as short as possible.
•
Use the appropriate tube diameter for the required fl ow rate and viscosity.
•
Recalibrate tubing regularly to maintain the best fl ow rate accuracy (for further information see
Calibration" on page 2-13).
•
After installing new tubing the pump should be run for 20-30 minutes to properly condition the tubing
and increase dispense accuracy (for further information see "To condition new tubing" below).To
condition new tubing:
Step 1: Unlatch the door, but fi rst
cut off the power to the pump by
disconnecting the line cord. Do
not assume that turning off the
switch is "safe enough".
