6. Use upper adjustor (E) to position the door panel
in the center of the lintel. After alignment is
achieved tighten locking nut.
7. Repeat same procedure for second traffic door
panel (bi-parting models only).
Adjusting the Tension
NOTE
The torsion spring mechanisms are adjusted at the factory
for normal operation of the traffic doors. Releasing the
tension completely is not advised and care should be taken
not to over-tighten as damage to the spring may occur.
To Increase Tension:
1. Open door panel to 90 degrees. Insert a
retaining tool (N) (not supplied) in the second free
hole of the adjusting ring (L) starting from the one
into which the pin is already inserted.
2. Allow the door panel to close slightly until the
retaining tool (N) inserted into the adjusting ring
(L) rests against the inside of the doorway.
3. Remove the pin and slowly recluse the door
panel until the inside hole of the mechanism
matches up with the new hole in the adjusting
ring.
4. Insert the pin (M) in the new hole.
To Decrease Tension:
The procedure is the same as increasing the tension
with the following two differences:
1. The retaining tool must be inserted only one
hole away from the pin.
2. When the pin has been removed, the door panel
must be opened instead of closed to insert the pin in
its new position.
NOTE
Supra Model door panels may be field modified. Ultra Model
door panels may be field modified up to 4” in width and 2” in
height.
