POLYETHYLENE MANHOLE ADJUSTING RINGS INSTALLATION INSTRUCTIONS

Clean the concrete cone or top slab with a whisk broom or chisel to obtain a flat seating surface, eliminating all rocks, gravel, blacktop, protruding concrete or frozen debris.
Apply an approved sealant tot he first HDPE ring. Place the sealant 360 degrees on the flat side of the ring, as close as possible to the male lip. (A second application of sealant can be applied between the first sealant and the holes, helping the first ring to seat level if surface irregularites are present).
Place the ring male lip down, inside the cone or top slab opening.***
Place sealant around the second ring on the flat side, as close to the male lip as possible, being careful to cover the entire 360 degrees of the ring. Install the second ring on top of the first, compressing the sealant by standing on the rings.
Continue step 4 using 4", 2", 1-1/2", 1-1/4", and 3/4" x 1-1/2" sloped rings as required for each manhole to obtain a height difference of 1/4" of grade after the casting is installed.
Prior to placing the casting, install an approved sealant to the top of the last ring so the sealant is between the casting and the flat portion of the top ring (all 360 degrees).
When directed by the engineer, wrap filter fabric around the top 1 to 2 inches of the concrete cone, the entire height of the rings, and the casting flange. Overlap the flange approximately 4 to 6 inches, (usually an 18" width of fabric is sufficient). Place dirt around fabric as necessary to hold in place.
***If the cone or top slab is eccentric, and does not allow the ring to seat flush, use a wood saw to cut a portion (usually 90-120 degrees is sufficient) of the male lip off until the ring can sit flush on the concrete.
