ADHESIVES For secondary contairnTient systems conveying alcohols or alcohol/gasoline blends, use 8000 or 7000 series adhesive. Follow the adhesive mixing instructions that are packaged with each kit. Refer to page 7 for infomnation on adhesive labeling. ADHESIVE MIXING When the weather is cool or ti -re adhesive has been stored in a cool environment (below 650F), pre -warm the adhesive kits. (Do not heat above 100°F) Empty all of the contents of the hardener. Never attempt to split a kit. Cut through the adhesive with the edge of the mixing stick to assist in mixing the two components. Mix until the adhesive has a uniform color and a consistent flow off the mixing stick. Wipe down the sides, bottom, and under the rim of the can with the mixing stick to assure complete mixture. FILLER MUST BE ADDED TO THICKEN THE ADHESIVE. The filler is packaged in pre -measured quantities for use with 7014 or 8014 and 7069 or 8069 adhesive kits. One bag of filler is used for each adhesive kit. Before adding the filler to the mixed adhesive, be sure both the adhesive base and hardener are thoroughly mixed together. All of the filler in the bag should be used. The thickened adhesive may be applied with either the brush or the stir stick provided in the kit. Refer to Table below for the number of adhesive kits required to bond containment fittings. TABLE 13.

Apply adhesive to both halves and to pipe (1 /16" min. thickness) r � _. Pipe must fit snugly into fitting socket so that no gap exists Assemble the containment fitting by Placing the half with the pre-installed threaded female inserts on the bottom. Do not insert pipe past scarfed area. Inserts must be used on 3" and 4" 901 elbows and tees for Closed Interstitial Monitored Systems. inserts are not required for Open Gravity Flow Systems. Prior to bonding the insert, spread the insert splice 3 or 4 times to relax the insert. The insert may be placed on the containment pipe or primary fitting for easy access prior to bonding of the containment fitting. Locate the inserts next to the inside radius of the containment fitting, as shown on drawing below. The split in the insert must be facing up. Do not allow insert to overlap itself. Number of adhesive kits per containment fitting is based on Use the bolts supplied with the clam shell fitting to assemble applying a 1/16" (1.6 mm) minimum thickness of adhesive to the fittings on the pipe.

JOINT ASSEMBLY FOR RED THREAD IIA SECONDARY CONTAINMENT PIPING After cleaning the inside surfaces (I.D.) of both halves of the two-piece fitting, apply a thick coating (1/16"/1.6 rrim minimum of filled adhesive to the entire I.D. of both halves of the fitting. including the flanges (flat bonding surfaces). Next apply a thick coating (1/16"/1.6 mm minimum) of adhesive to the scarfed or sanded surfaces of the pipe ends. NOTE: Prior to bonding, make sure the pipe fits snugly into the socket ends of the two-piece fittings and there are no gaps between pipe ends and fitting sockets. A properly bonded joint should have adhesive visible from all bonded surfaces. NOTE: Do not disturb a completed containment piping joint when assembling additional joints. The adhesive must be fully cured before applying stress to the assembled joints. Read and observe the filled adhesive Instructions supplied with each adhesive kit. 20
