7 Insul-Pipe Systems Installation instructions For Below Ground Installation of Field insulation kits For Pipe with Plain End Couplings Read these important instructions carefully Following Assembly and testing: 1. Seal exposed end of insulation with mastic provided by I-PS at all field cuts. 2. Insulation materials for coupling joints consist of a PVC wrap, A&B Component Pour Urethane, and sealant tape. 3. Insulation material for fittings consists of an A&B Component Pour Urethane, PVC fitting covers, and sealant tape. Fittings: Step one: Position and strap Roll PVC Fitting Extension over Jacket of adjacent pipe seal seams with self seal tape. Step two: Create 2 hole in and wrap molded PVC cover over the fitting and extensions and tape in place. Fitting cover should overlap a few inches onto extension and create a mold for the pour between adjacent pipes over the fitting. Step three: Measure urethane components according to attached chart in equal amounts in preparation for mixing in separate bucket. Stir with paint mixer stick or electric drill for volume of 2 quarts or more in clean mixing bucket. Wait until the foam reacts (starts to cream) and pour quickly into mold. Insure that foam has completely filled mold and spills out of hole. Second pour if necessary into any voids. Step four: After foam has hardened, trim off any excess and seal the fitting cover with self-sealing tape provided by I-P S. Inspect seams for possible release of foam, trim and re-tape. Couplings: Cover coupling with roll PVC provided, sealing seams with tape provided. Poke a hole in sleeve and pour urethane foam into the annular space. Wait for it to react, then clean off the excess and seal with tape provided. 5 PE AB FILL COUPLE AND FITTING AND EXT

In no event shall Insul-Pipe Systems be liable for incidental or consequential damages. Handling and storage Insul-Pipe Systems sections should be handled with care when being unloaded and placed on the jobsite. Damage to the carrier pipe or jacketing may occur if the material is dropped or handled roughly. Webbing belt lifting slings should be used on sections too heavy to be handled by hand. Handle with care Check shipment for damage when received. Make note of any damaged goods on the freight bill. Keep a signed copy of the freight bill for filing a claim through the Freight Company. Storage at the Job site If the pipe is not ready to be installed immediately when received on the job, then it may be stockpiled. Store on level ground and protect ends from debris, dirt, etc. Do no stack more than six layers high. Store in a convenient location away from possible damage from construction equipment and vehicles. Stringing the pipe Pipe when strung, should be placed as near the trench as possible and on the opposite side of the excavated earth. When pipe gaskets are received separate from the pipe, install them in the gasket race at the time of assembly. 1

10 INSUL-PIPE SYSTEMS Installation instructions for Carrier pipe field connections Joints in the field Full joints may be cut to desired length in the following manner: 1. Determine the exact length of carrier pipe desired. 2. Measure, mark and cut pipe all the way through at using the proper cut-off tool for the type of pipe being used. 3. Cut off 4 to 6 of the jacket and insulation to allow room for fitting installation (see amount on factory end). Do not cut into the carrier pipe. Jacket may be cut with a hacksaw or carpenter s saw. Insulation should be cut with a knife down to the carrier pipe. Remove cut off insulation and jacket, clean exposed carrier pipe and proceed with installation. 4. Seal exposed end of insulation with material provided by Insul-Pipe Systems. 2
