Special Instructions:
Fusible link must never be replaced with a piece of wire. On first inspection,
make sure that damper is not installed backwards. In all cases, the air movement
should tend to close damper.
Items to Check & Initial Completion:
1.___ Determine that access door is reasonably air tight and latches properly.
2.___ If damper is closed, check for ruptured fusible links, broken attachment or
hinges, damage, corrosion, etc.
3.___ Remove fusible link and check for proper rating.
4.___ Determine that damper is self-closing and properly latches. Adjust if
necessary.
5.___ Check operation of motorized damper control. Lubricate friction points and
exercise damper to insure complete freedom of movement. Remove old or
excess lubricant.
6.___ Each year, in areas of vibration, install new fusible links of proper
rating and tensile strength.
7.___ Reinstall fusible link (locations where vibration is not a problem).
8.___ Close access door and check for wind noise.
Tools & Materials:
