Apropedy <br />bonded joint should have adhesive visible from all bonded <br />surfaces. <br />NOTE: Donot disturb ocompleted containment piping joint <br />when assembling additional joints. The adhesive must be <br />1b|kv cured before applying stress to the assembled joints. <br />Read and observe the filled adhesive instructions supplied <br />with each adhesive kit. <br />Electric Heating Collar <br />(Refer to Bulletin No. F6640 for complete operating <br />imstrmctimmm') <br />Approximate adhesive cure time when <br />using electric heating collars nnclam <br />shell secondary containment fittings iw =~ <br />250o3Ominutes porjoinL See pages <br />10-11 for additional heating collar <br />information. <br />Two heating collars are required for each end ofmclam shell <br />containment fitting bond. <br />For Saddles - CuhnQ saddles can be accomplished by <br />wrapping aheating collar over the saddle outlet. For outdoor <br />installations, plate wind <br />shields on both sides ofA�k <br />the saddle to prevent heat <br />loss. Total cure time must <br />be two hours for saddles. <br />Allow the saddle to cure <br />and cool down to ambient temperature before bonding or <br />threading in the side run. Do not use chemical hamd packs <br />to cure saddles. <br />Allow the joint to return to ambient temperature before <br />applying stress to the joint. <br />Industrial Heat Gun <br />An industrial heat gun and heavy duty aluminum foil may <br />also be used to cnambe o mini oven around the clam shell <br />secondary containment fitting.
