Match the fusible link to the exact damper listing and approved submittal, keep it undamaged, and replace it only with the specified listed part.

Stop if

• Can we verify the correct fusible-link rating and listed replacement part for this exact damper before I install it?

Check

• Identify the damper model and listing
• Read the link marking without guessing
• Check for bends, corrosion, paint, contamination, or damage
• Verify the replacement part and orientation
• Confirm required inspection or functional test
