Over time the water inlet strainer can become clogged and reduce water flow. Reduced water flow limits the system cooling and can result in the instrument shutting down during analysis and triggering error or warning messages such as:
Steps to Follow
Turn off the water chiller or heat exchanger.
Locate the water manifold on the back left corner of the ICP-MS.
Place a container or absorbent material under the water filter.
Unscrew the water filter drain plug with a 17 mm open ended wrench while holding the brass Y piece with a 23 mm wrench to keep it from spinning.
Remove the drain plug.
Remove the strainer from the housing.
Clean the strainer with tap water and a soft brush.
Refit the strainer.
Be sure that the gasket is correctly positioned before closing the cap, and reinstall the drain plug.
Turn on the chiller or heat exchanger and check for leaks.
