Ensure the mounting thread (3\/4-14 NPT) is clean and free of debris. When installing the housing, tighten the dome cover securely to maintain the explosion-proof seal. The cable seal grip should accommodate your cable diameter; select the appropriate grommet size from the provided set (1\/8-3\/16 in, 1\/4-5\/16 in, or 5\/16-3\/8 in).\u003c\/p\u003e\u003cp\u003ePosition the probe so that the tip achieves the recommended gap for your application. Use the probe penetration dimension (9.2 in) to verify correct insertion depth. For hazardous area installations, follow all local regulations and ensure the housing is properly grounded.\u003c\/p\u003e\u003ch2\u003eMaintenance \u0026amp; Reliability\u003c\/h2\u003e\u003cp\u003eRegular inspection of the housing and probe is recommended to ensure long-term reliability. Check for any signs of wear on the O-rings and thread seal. Verify that all fittings remain tight and that the cable seal grip maintains a proper seal. Clean the exterior with a mild solvent if needed, but avoid abrasive materials that could damage the aluminum surface.\u003c\/p\u003e\u003cp\u003eThe 21000-28-05-00-092-03-02 is designed for minimal maintenance, reducing downtime and operational costs.
