Tips to Maximize Your Product's Lifespan
Proper installation maximizes protection: mount surge-protected units within 6 feet of your main electrical panel to minimize voltage drop. During setup, verify proper grounding by checking continuity with a multimeter—poor grounding compromises surge protection effectiveness. Test your EPO function quarterly by triggering the manual shutdown button; this ensures mechanical components remain responsive. Keep air circulation around the unit clear (minimum 4-inch clearance on all sides) to prevent thermal stress on internal components. If you experience repeated EPO activations, document voltage readings and contact your utility company—persistent issues may indicate broader grid problems requiring professional investigation. Periodically inspect the unit for corrosion or moisture intrusion, especially in coastal or humid environments.
