INTERMEDIATE DEFLECTION MEASUREMENT After backfill is brought to the top of the tank,make an MINIMUM TURNBUCKLE DIAMETER MINIMUM intermediate measurement of vertical deflection according to the TANK (BY E) WIRE ROPE instructions in Section 13. DIAMETER HOOK JAW EYE DIAMETER TEST 4' 3/4" 1/2" 1/2" 3/8" After the tank has been measured and vertical deflection is 6' 3/4" 1/2" 1/2" 3/8" determined to be within the limits specified by Xerxes,the tank 8' 11/4" 3/4" 3/4" 1/2" must be pressure tested to ensure that no damage occurred during installation.The procedure in Section 2 Pre-installation 10' 11/4" 3/4" 3/4" 1/2" Testing should be followed,soaping all exposed areas of the tank 12' 11/4" 3/4" 3/4" 1/27' and all fittings. Because most of the tank exterior is no longer visible,the tank TABLE 7-3 must be tested by checking the gauge for one hour at the test manifold for any drop in pressure.Carefully relieve the pressure in the tank and remove the Quick Disconnect assembly from dry 31/4" Double Wall tanks. -�1-8/s" Do not use air pressure to test tanks that contain flammable or combustible liquids or vapors and do not perform any post- installation pressure test.The fuel/air mixture may explode and cause death,severe personal injury,or property damage.

The tank may be ballasted after the backfill is even with the top of the tank and post-installation testing,if applicable,has been successfully completed.Only under wet-hole conditions,as described in Section 6,should ballast be added before the backfill is even with the top of the tank.When filling the tank,make sure FIGURE 7-4A the tank is properly vented.The vent must be large enough to allow the displaced air to escape. zi. °' - il
