2.2.3. When hoisting and guiding the tank, see Figures 2-1 and 2-2, and follow these instructions: • choose suitable lifting sling(s) for the tank being installed • when using multiple lifting lugs, the angle of the lifting sling should never exceed 30 degrees from vertical—see Figure 2-1 • when the tank is shipped upright, use all lifting lugs to unload and install the tank—see Figure 2-2 • some tanks are rotated on the truck for shipping purposes. These tanks have extra lifting lug(s)to aid in the loading/unloading process—see Figure 2-2 • use the lifting lugs that are situated on top of the tank in its rotated position to offload the tank from the truck and place it on the ground. • to install the tank, once it has been placed on the ground, carefully rotate the tank to its upright position and then use all lifting lugs situated on top of the tank in its upright position—see Figure 2-2 TOP OF TANK IN Lifting lugs to be ROTATED POSITION used when tank is in rotated position. Lifting lugs to be used when tank is in upright position. TOP OF TANK IN UPRIGHT POSITION 7 Lifting lugs to be used when tank is in upright position. 2.2.4. Do not wrap chain or cable around the tank at any time, including when securing the tank on the ground. 2.2.5. Use guide ropes to guide the tank when needed. A WARNING Do not use guide lugs for lifting. Failure to follow this warning could result in death, serious injury or property damage. 2.2.6. When handling a tank with a bottom sump orfitting, always take extra care so that the bottom sump or fitting is not damaged by contact with any other object, such as the truck bed or the ground. 2.3. STORING TANKS 2.3.1. Whenever a tank is temporarily placed above the ground at the site, place it on a smooth, solid, level area that is clear of large rocks, trash and debris, and then chock it in place to prevent rolling. A WARNING Always chock the tank. The tank is heavy and has a large surface area. The tank will roll on sloped surfaces and could be blown about by the wind. Movement of the tank could result in death or serious injury. 2.3.2. Tie the tank down if high winds are expected. Do not use wire rope or chains. Doing so could damage the tank. 2.3.3. Never place tie -down straps over collars, reservoirs or access openings 2.3.4. Whenever tank is temporarily placed above the ground at the site, always take extra care so water does not enter the collar. We recommend that the tank be rotated and/or the collar covered. 2.3.5. Ensure that the tank is UV -protected if it will be stored above the ground for an extended period of time, typically 12 months depending on the geographic location of the installation. NOTICE If water enters the collar, it could freeze and could result in damage to the tank and/or collar. 3: PREINSTALLATION INSPECTION AND TESTING 3.1. GENERAL A WARNING Do not conduct preinstallation testing while the tank is on a trailer. Failure to follow this warning could result in death or serious injury. NOTICE Do not put product in the tank until all necessary preinstallation inspection and testing is completed. Failure to follow this notice could result in property damage 3.1.1. The applicable inspection and testing procedures in sections 3 and 4 must be performed to validate the applicable limited warranty. 3.1.2. All tanks are tested and inspected at the factory prior to shipment. However, in order to verify the absence of any damage resulting from shipping or handling, prior to installation all tanks must also be inspected at the site. Some tanks must also be tested at the site prior to installation according to the applicable procedures. A WARNING Do not lift or hoist a tank under pressure. Failure to follow this warning could result in death or serious injury. 3.1.3. Not all tanks are pressure -testable in the field. We recommend the pressure test on any tank that can be safely sealed for testing. See section 4 for pressure -test instructions. If a tank needs to be hydrostatically tested, see section 4 and follow those instructions. 15
