10 NOTE: Your tank will arrive with a Quick Disconnect assembly (see Figure 2.3 OD) unless you have a liquid -filled interstitial space tank. If the tank is not configured as shown in the illustration prior to pre -installation testing, call the Xeres Coordinator at the plant nearest you or the Technical services Department at Xeres' headquarters. QUICK DISCONNECT ASSEMBLY NOTE: In order to test the primary tank alone, the test hose must NOT be connected to the service fitting - keep the nylon tie in place. PRIMARY (INTERNAL) TANK TEST 1. Connect the test manifold to an available service fitting. Remove the remaining fittings, redope, and reinstall fitting plugs. 2. Pressurize the primary tank to 5 PSIG; add or remove air as necessary and allow the pressure to stabilize. Close the valve on the test manifold supply line. 3. Monitor the pressure for one hour. Soap test all service fittings and manways. Watch for active air bubbles which indicate a leak. ------------- - NYLON TIE PRESSURE RELIEF DEVICE _--� FROM COMPRESSOR QUICK DISCONNECT AIR SUPPLY VALVE ASSEMBLY AIR SUPPLY GAUGE MONITOR FITTING SERVICE FITTING FIGURE 2-3 QO SECONDARY (EXTERNAL) TANK TEST 1. Maintain the pressure in the primary tank. 2. Free the hose from the service fitting by cutting the nylon tie. 3. Insert the hose into the Quick Disconnect check valve (found at the top of the service fitting). This will allow air to transfer from the primary to secondary tank. 4. Pressurize to 5 PSIG. Add or remove air via the supply valve as needed and allow the pressure to stabilize. Close the valve on the test manifold. Disconnect the air supply line. 5. Monitor the pressure for one hour. Soap the entire exterior of the tank and watch for active air bubbles which indicate a leak. When the test is complete, carefully release the air pressure from the tank by opening the supply valve. The air supply line already should have been disconnected. When the air flow from the supply valve stops, remove the test manifold. PRIMARY (INTERNAL) TANK TEST NOTE: Keep the tank vertical (the reservoir on top) during the preinstallation testing or the liquid (typically brine) may drain from the reservoir. 1. Open one service fitting and the fitting on the reservoir. Check for liquid in the reservoir - it should be about half full. Do not open the monitor fittings - liquid (typically brine) will be lost. Remove the remaining fittings, redope, and reinstall fitting plugs. 2. Visually check the interior of the tank for liquid - there should not be any. Install the test manifold in the open service fitting. Connect the pressure source to the test manifold. (See Figure 2.4). 3. Pressurize the primary (internal) tank to 5 PSIG. Add or remove air as necessary and allow the pressure to stabilize. Close the valve on the test manifold. Disconnect the air supply line. 4. Monitor the pressure for one hour. Soap all fittings and manways and watch for active air bubbles which indicate a leak. Check the reservoir for bubbles in the monitor fluid. 5. Release the pressure from the primary tank.

Check the exterior of the tank for monitoring liquid - if liquid is found, wipe the tank dry and verify that the liquid does not reappear. Lift the tank to check the bottom. Do not roll the tank. 0 DANGER: Do not stand under the tank while it is being lifted. When the test is complete, remove the test manifold. Visually check the interior of the tank for liquid. Replace the protective covers in the service fitting and the reservoir fitting. K
