Replacing the sample manager leak sensor

Users or Waters field service personnel can replace the sample manager's leak sensors.

The sample manager has lower and upper leak sensors. The leak sensors monitor for fluid leaks at the column heater and sample manager and stop system flow when either sensor detects approximately 1.5 mL of accumulated fluid. Faulty leak sensors can result in undetected fluid spills.

The procedures for replacing the leak sensors are identical.
