I,& A2. Bed and Backfill (cont.) Approved Gravel Must consist of clean, natural- ly -rounded aggregate with a mix of particle sizes not less than 1/8" or more than 3/4". Approved Crushed Stone or Crushed Gravel Must be washed with angular particle size not less than 1/8" or more than 1/2".

TANK DAMAGE CAN RESULT. • All tanks must be tested for leaks prior to installation. Use the visual air/soap test: • Visual Air/Soap Test - to be performed on all tanks. ❑ Warm weather soap solution - 5 gallons of water with 8 ounces of household dishwashing detergent. ❑ Freezing conditions soap solution - substitute 1 gallon of automotive windshield washer solution for 1 gallon of water. ❑ Cover entire tank outer surface with soap solution.* ❑ Cover all fittings with soap solution. ❑ Carefully inspect for leaks as indicated by bubbles. *Exception - double-wall tanks with annular space filled. • In the unlikely event a tank leak is discovered, discontinue the installation and immediately call the Owens-Corning Field Service Department to schedule a repair. See phone numbers on page 2. Testing Single -Wall Tanks These tests must be performed before installing tanks: • Remove fitting plugs. • Apply pipe dope and reinstall fitting plugs. • Pressurize tanks. ❑ 4' through 10' diameter tanks to 5 psi maximum. ❑ 12' diameter tanks to 3 psi maximum. ❑ Use a pressure relief valve. • Soap the tank and carefully inspect for leaks as indicated by bubbles. • Maintain test pressure and continue inspection for at least 30 minutes. DO • Use an air gauge with 1/4 or 1/2 lb. increments. • Make sure you understand these instructions. If in doubt, call the Owens-Corning Installation Manager in Toledo at (419)-248-7317. DO NOT • Approach endcaps or manways while tanks are under pressure. This could result in personal injury. • Lift or hoist a tank under pressure. This could result in personal injury. • Use a vacuum gauge. Testing Double -Wall Tanks with Dry Annular Space This section is for tanks which do not have monitoring tracer fluid installed. If tank arrives at site with monitoring fluid installed, use instructions for Double -Wall Tanks with Annular Space Filled on page 4. For All Tests: DO • Install air gauge at the fitting where the air pressure hose is connected to the tank. • Install a second gauge at the other monitoring fitting. • Use an air gauge with 1/4 or 1/2 lb. increments. DO NOT • Lift or hoist a tank under pressure ( to avoid potential injury). Outer Wall Test Step #1 • Close manifold valve between primary tank and annular space. • Pressurize primary tank to 5 psi maximum. • Use a pressure relief valve. Do not connect the air supply directly to the monitoring fitting or tank damage will result.
