Maintenance
NOTES
• After removal of the wires, check the strips of fiber glass for damage; replace if necessary.
• Check the condition of the tensioning springs at both ends of the seal beam; replace if necessary.
• Using the seal beam without the springs may cause the sealing wires to break.
• Check contact plate for damage; replace if necessary.
INSTALL THE SEALING AND CUTTING WIRES AS FOLLOWS:
1. If necessary, install new strips of fiber glass on the seal beam.
2. Insert the new wires behind one of the mounting plates and tighten the screws; make sure that the end of
the wires line up with the bottom edge of the mounting plate.
3. Position the wires across the seal beam and loosely install the second mounting plate.
4. Carefully clamp the seal beam upside down in a bench vice.
5. Pull the wires as tightly as possible with a pair of pliers and secure the second mounting plate by tightening
the screws.
NOTE
1. The wires can be further tightened by slightly loosening the screws of one of the mounting plates.
2. Pull the wires one-by-one tighter with a pair of pliers.
3. Re-tighten the screws after the correct tension has been achieved.
4. Cut the end of the wires flush with the bottom edge of the mounting plate.
