24. Actual capacities shown will be reduced if an overfill -protection device is installed in the tank. 25. Actual tank height may be greaterthan that shown with actual tank diameter when certain accessories are installed on a tank. 26. Load height during shipping may vary due to tank placement on the shipping trailer. 27. When using Appendices B1, 62,63 and B4 for determining the weight of a multicompartment tank, you must select the tank size in the chart given the total nominal capacity of all compartments. Note the following: • Single-wall (SW) tanks with flat baffle(s) installed are not considered multicompartment tanks. Refer to one -compartment tank data for these tanks. • For double-wall (DW) tanks with a dry interstice, use the DW Dry Weight column. • For double-wall (DW) tanks with a factory -installed TRUCHEK' wet monitoring interstice, use the DW Wet Weight column.

This section of the Installation Manual contains information that you need to consider before a tank is delivered so that you are prepared to proceed with installation. This includes, but is not limited to, equipment needed for installation, backfill material selection, excavation requirements, tank anchoring options, taking diameter measurements, and onsite testing requirements. 1.1.2. The following list is to be used as a guide for equipment recommended fortank installation: • excavation equipment capable of producing a level -bottom hole and placing backfill material at any point in the excavation • suitable lifting equipment capable of lifting and placing the tanks and associated tank anchors • spirit level • transit or grade level • 50 -foot [15 -meter] tape measure • tamping rod(s) • pipe wrenches and appropriate pipe joint compound • a test manifold for each pressure -testable tank or compartment (reference Figure 4-1) • source of pressurized air capable of 6 psig [40 kPa] or inert gas • soap and water solution (during freezing conditions, a suitable solution such as windshield wiper fluid may be added to the soap and water mixture) • soft cloth, brush or hand-held pneumatic sprayer • hand shovel • lifting sling(s) • soil compacting equipment (if necessary) 1.2. BACKFILL MATERIAL AND GEOTEXTILE 1.2.1. GENERAL 1.2.1.1. Tanks shall be installed using select rounded stones or crushed stones as primary backfill material. See section 1.2.2 for specifications of primary backfill material and Appendix C. 1.2.1.2. Alternatively, tanks shall be installed using primary backfill vertically up to at least 75 percent of the tank diameter and secondary backfill above the primary backfill. See section 1.2.3 for specifications of secondary backfill and Split Backfill Instructions (Appendix D) for more information regarding this alternative. 1.2.1.3. Using backfill material other than that specified here without prior written authorization from us will void our obligations under the applicable limited warranty. NOTICE Using other than specified backfill material could cause tank failure, or could result in damage to the tank and/or surrounding property. 1.2.2. PRIMARY BACKFILL 1.2.2.1. Primary backfill material must meet the following specifications: • Material is to be clean, free-flowing, and free of dirt, sand, large rocks, roots, organic materials, debris, ice and snow. • Backfill material shall not be frozen or contain lumps of frozen material at anytime during placement and compaction.
