4-7. ASSEMBLY. After the tank has been unpacked, deployed, and inspected, perform the following steps in
order.
a. Site Preparation.
CAUTION
All metals on the tank and the tank accessories are aluminum alloy. Do not
drop or strike these items. Scuffed or bent accessories will not assemble
properly.
(1) For ease in emptying the tank completely, dig a hole under the down slope drain fitting.
(a) Fold about 10 feet (3.05 meters) of each end of tank back over the rest of the tank to expose
connections for drain assemblies located on the bottom of the tank.
(b) At the point where the drain fitting strikes the ground, dig a hole approximately 36 inches
(91.5 centimeters) long by 36 inches (91.5 centimeters) wide and 3 inches (7.5 centimeters)
deep. Keep the drain fittings contact points centered.
(c) Dig a 3 inch (7.5 centimeters) wide by 3 inch (7.5 centimeters) deep by 10 inch (3.05 meters)
long.
(2) Attach Drain Hoses and Fittings.
(a) When attaching drain hoses to the drain fittings, wrap the drain hose male threads with 3 or 4
layers of Teflon tape to ensure a positive seal.
(b) Remove drain valves from drain hoses by unscrewing drain valve from hose (if attached):
(c) Remove drain plug from each drain assembly and attach a drain hose to each drain
assembly.
(d) Unfold tank ends to lie flat in original position. Hoses should extend from bottom of tank.
(e) Connect drain valves to drain hoses. Ensure that valves are closed. When attaching drain
valve to drain hose, wrap the drain hose male threads with three or four layers of teflon tape
to ensure a positive seal.
(f) Remove dust caps and dust plugs from tank, vent fitting and filler discharge fittings. Remove
dust plug and dust cap from 6 inch gate valve. If the sealing surfaces of the couplings are
dirty, wipe with a clean cloth.
(g) Inspect female coupling half (1) and vent pipe (2) for cleanliness. (See figure 4-6)
