Door Panel Adjustments - Pioneer 500 ST Installation Manual

11. Door Panel Adjustments

During normal operation, the tension pipes should run in close proximity of each other. The clearance
between the tension pipes should normally be between 1/4" to 1/2" (6.35 mm - 12.7 mm). There are two
situations pertaining to the tension pipes that may cause problems with door operation. If the tension pipes
are too far apart, the tension pipes will not repel each other. This causes poor contact between the hook &
loop. On the other hand, if the tension pipes are riding one another (i.e. touching one another), the door
panel material does not flow evenly, thus leaving wrinkles in the panel instead of a stretched, smooth &
even appearance.
Adjustment Procedures
The clearance between the tension pipes can be adjusted by raising or lowering the door panels. Each door
has three panels: (1) The inside panel (panel facing the inside of building) is attached to the back plate. (2)
The center panel is attached to the roller. (3) The outside panel (facing the outside of building) is attached
to the front bar. Adjustments are made to the inside panel and/or the outside panel.
To adjust the height of the outside tension pipe, raise or lower the outside door panel by detaching the panel
hook & loop from the front bar, and raising or lowering the panel. Then re-attach the panel loop to the
hook on the front bar. Be sure to keep tension pipe level during this procedure.
To adjust the height of the inside tension pipe, raise or lower the inside door panel by detaching the panel
hook & loop from the back plate, and raising or lowering panel. Then re-attach the panel loop to the hook
on back plate. Be sure to keep tension pipe level during this procedure. Install Tek screws through the
panel material and into the back plate to securely hold the material in place.
