Replacing the Sample Pump Tubing

The tubing for the sample pump loses elasticity over time and must be replaced annually to ensure
proper flow rates. The tubing must be purchased from GE Analytical Instruments; use of tubing from
other sources or failure to replace the tubing on the prescribed replacement schedule will affect
Analyzer functionality.
Installation of the pump tubing requires access to the inside of the
Analyzer. To avoid potentially dangerous shock, disconnect the power
cord before opening the Analyzer's front panel.
