Detector Module Replacement
Note: Check the O-ring is in place on the enclosure base before replacing the detector module.
Note: Take proper precautions to prevent damage from electro-static discharge.
Note: In the event of a fault, the Detector Module can be replaced to enable rapid maintenance.
Note: Use a strap wrench at low temperature if the enclosure binds.
