This document is the FlexStorm Wall Mount Filter Operation & Maintenance Guide. Installation and maintenance guidelines discussed.

Installation Instructions say to enter manhole opening with inlet filter(s) and mounting hardware. Align filter frame with curb opening and mark centerline of each corner hanging bracket. Using supplied brackets, mark location of the concrete anchors 1”(25 mm) below the top ledge of concrete. Drill ¼” (6.4 mm) pilot holes to a depth of ½”(12.7 mm) greater than the length of the ADS supplied fasteners. Secure wall mount brackets using ADS supplied concrete fasteners. Hang FlexStorm inlet filter(s), then check fit before exiting drainage structure.

Maintenance Guidelines are to enter manhole opening. Lift filter frame hangers off wall mounted brackets and remove from manhole opening. Clean filter and examine bag assembly for rips, tears, or hydrocarbon oil pouch saturation (when applicable). Replace bag if rips, tears, or loose bands are observed. Replace hydrocarbon oil pouch every 60-90 days or when discolored, to maintain effectiveness. Remount filter(s) on brackets. Alternatively, you can service with a truck mounted vacuum.

An example of an operation & maintenance log with Inlet ID, date, task performed and initials included.

A detail showing the sample configurations is provided.
