5.4. INSTRUCTIONS FOR REPLACING THE FUSIBLE LINK<br />
When a fusible link breaks the damper closes and will remain closed as long as the fusible link remains<br />
unfixed. To fix the fusible link you must either A) replace the broken link, or B) replace the whole fusible link<br />
package with a new fusible link package. In case B remember to rewire the junction box (or pneumatic lines in<br />
case of pneumatic damper) exactly like it was before.<br />
1. Open fixing bolts (figure 2) and withdraw the complete thermo intermediate link.<br />
2. Press the spring (figure 3) and insert new fusible link to the spring. Note: Ensure that the replaced<br />
fusible link has the same temperature rating as the old one.<br />
3. Reinstall the thermo intermediate link and tighten the fixing bolts (figure 5).<br />
