Replacing the Pinch Valve Tubing
Pinch valve tubing in the Analyzer’s pinch valves must be replaced periodically to ensure proper operation of
these valves. The tubing should be replaced after one year of operating time for neutral pH samples. If samples
are acidic or basic, the tubing should be replaced every 3 to 6 months. The operating life remaining in the tubing
is shown on the Analyzer’s
Main
screen and on the
Consumables
screen. For this procedure, the Analyzer
should be powered on. Contact GE Analytical Instruments at 303. 444.2009 or 800.255.2595 for a replacement
