PLASTE OELUTROKI' Double-Wa INSTALLATION INSTRUCTIONS Tank i 1. GENERAL The PLASTEEL' ELUTRON' underground tank is a U.L. Listed Jacketed tank providing corrosion protection and 360° secondary containment per U.L. 1746 and 58. ELUTON' underground tanks must be installed according to these installation instructions, the latest issue of the Flammable and Combustible Liquids Code, N.F.P.A. 30 for underground tanks and the authority having jurisdiction. The installer and/or owner must read and be familiar with the entire installation instructions and Appendix A prior to installing the ELUTR' tank. To activate the PLASTEEL' ELUTO'Tank Warranty, a completed and signed Certificate of Installation for the PLASTEEV ELUTRO' Underground Tank must be returned to the manufacturer. For additional installation references, consult the current editions of: — Petroleum Equipment Institute, RP -100 — American Petroleum Institute, RP -1615. Prior to setting tank in hole, inspect exterior for damage. If tank exterior is damaged, call factory regarding correct repair procedures. Exterior damage is indicated when the blue color of the FRP laminate has shown a white fractured pattern. Good construction engineering practice, common sense and safety must prevail during this phase. ELUTR ' tanks are not to be dropped or rolled off of the delivery vehicle onto the ground or into the hole. The lifting hook or hooks provided must be used in combi- nation with the proper capacity unloading equipment. It is the responsibility of the owner to provide the qualified personnel and safe, proper unloading equipment, with specific consideration given to tank weight and reach distance to set tank in excavation. The preferred lifting cable included angle is 60° and must never exceed 120°. A spreader bar may be used to achieve this angle. IV. EXCAVATION DEPTH, BEDDING AND BACKFILL Follow all applicable local regulations and codes. When excavating, allow a minimum clearance of 6" for backfill around the tank. For minimum burial cover, consult N.F.P.A. 30. If burial cover over top of tank exceeds five (5) feet, consult factory. Backfill materials should be clean, debris free, sand or pea gravel. Hydrocarbon exposed sand or pea gravel may be re -used if approved by the AHJ. Native sand may be used if approved by the tank man- ufacturer and the AHJ. Allow a minimum of 12" of backfill between traffic slab and all appurtenances that are attached to the tank. Damage to tank may occur if surface traffic loads are transmitted directly to tank. ■ CAUTION: The decision to use an anchoring system is the responsibility of the owner. Damage to the tank may occur if the tank is subjected to movement. Consult the factory for number, size and type of holddown assemblies required when using a concrete pad under the tank. You may set and securely anchor the ELUTRON' tank on the pad with a minimum of 6" of backfill between tank bottom centerline and the pad. Upon local implementing agency approval, you may set and securely anchor the ELUTRO' tank directly on the smooth, flat pad taking care to place a 12" wide x 1" thick piece of felt between the entire tank bottom centerline and the pad to minimize damage during placement. Consult factory for other anchoring techniques. PRE -INSTALLATION: Aboveground, prior to replacement of tank in excavation, precisely follow one of the three testing options cited in Appendix A attached. Do not deviate from these procedures. If the SLUT' tank is delivered with a vacuum on the interstice, refer to Option #2 of Appendix A. CAUTION: IF OPTION #3 IS USED. DO NOT APPLY ANY PRESSURE TO THE INTERSTICE BEFORE THOROUGHLY UNDERSTANDING AND FAITH- FULLY FOLLOWING THE PROCEDURES CITED IN OPTION #3 OF APPENDIX A. DAMAGE TO TANK MAY OCCUR IF YOU DEVIATE FROM THE PROCEDURES AND SPECIFICATIONS. POST -INSTALLATION: Complete the backfill procedures to the top of the tank. Complete all piping and connections ensuring that unused openings are secured tight with threaded steel plugs. Apply a 5 PSIG pressure test in the primary tank and check for tight- ness of piping connections and tank manhole covers. Gauge should be checked prior to testing for accuracy and have a maximum limit of 15 PSIG. CAUTION: THE PRIMARY TANK TEST PRESSURE SHALL NOT EXCEED 5 PSIG. DAMAGE TO TANK MAY OCCUR. ISOLATE PIPING FROM TANK BEFORE TESTING THE PIPING AT HIGHER PRESSURES. The interstice (annular space) will be tested using option #2 or #3 in Appendix A. OPTION: See Appendix B for procedures to perform the Interstitial Vacuum Test that has been third party evaluated to meet the EPA tank tightness test protocol. VII. VENTING The PRIMARY (inner) tank must always be vented to atmosphere. The interstitial space does not require venting. However, local codes may require such interstitial venting. Comply with N.F.P.A. 30. CAUTION: DO NOT MANIFOLD VENT FROM PRIMARY TANK TO VENT FROM INTERSTITIAL SPACE. These procedures must be performed prior to completion of backfill and AFTER TESTING. To ensure complete corrosion pro- tection, the following instructions must be followed: a.
