8) Check to see that the Diaphragms are in usable condition. Diaphragms which are bowed
or have bent legs must be replaced.
9) Check that the Fender Panels are properly attached with the Mushroom Washer
Assemblies. Damaged Fender Panels and Transition Panels must be replaced.
10) Check the gaps between Fender Panels. The maximum gap allowed for these overlapping
parts (including Fender Panels overlapping panels behind the system) is 3/4” [20 mm] for
narrow systems and
1.00” [25 mm]
for wide systems (p. 53). Ensure the Mushroom
Washer Assemblies are tightened until the nuts make contact with the bolt shank. If the
gaps between the Fender Panels are still too large it may be necessary to replace bent
parts.
11) Replace all crushed Cartridges. Refer to Cartridge Placement on page 37 or 51.
12) Check the torque of all anchor bolts on the system (p. 13).
13) Check to be certain that the site is free from excessive dirt or debris. The QuadGuard
