0 I]nuRLF WAf I TANK 1Urn4 nRv iumnii TITIAI epi NOTE: Your tank may arrive on site with a hose/valve assembly (see Figure 2-3 HV) or with a Quick Disconnect assembly (see Figure 2-3 DD). If the tank is not configured as shown in one of the illustrations prior to pre -installation testing, call the Xerxes coordinator at the plant nearest you or the technical services department at Xerxes headquarters. NOTE: In order to test the tank, the hose/valve assembly must be connected from a monitor fitting to a service fitting. PRIMARY (INTERNAL) TANK TEST 1. Open one service fitting and the monitor fitting which is not connected to the hose/valve assembly. Check to see that all remaining service and monitor fittings are properly doped, plugged and tightened. 2. Close the valve on the hose/valve assembly. Install the test manifold in the open service fitting. Connect the pressure source to the test manifold. (See Figure 2-3 HV). 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. 4. Monitor the pressure for one hour. Soap all fittings and man - ways and watch for active air bubbles which indicate a leak.

Once the valve on the hose/valve assembly has been opened, do not close it until all testing is complete and all test pressure has been released. 1. Maintain the pressure on the primary tank. Plug the monitor fitting which was previously open. Slowly open the valve on the hose/valve assembly and pressurize the secondary (external) tank to 5 PSIG. Add or remove air as needed and allow the pressure to stabilize. Close the valve on the test manifold. Disconnect the air supply line. 2. 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 air supply valve. The air supply line should already have been disconnected. Remove the test manifold. QUICK DISCONNECTASSEMBLY 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) TANKTEST 1. Connect the test manifold to an available service fitting. Check to see that all remaining service fittings are property doped, plugged and tightened. Ej 2. Open the monitor fitting not connected to the hose quick disconnect assembly. 3. 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. 4. Monitor the pressure for one hour. Soap test all service fittings and manways. Watch for active air bubbles which indicate a leak.

Maintain the pressure in the primary tank. 2. Plug the monitor fitting which was previously open. See Step 2 3. Free the hose from the service fitting by cutting the nylon tie. 4. 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. 5. 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. 6. 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 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 — brine will be lost. Check to see that all remaining service and monitor fittings are property doped, plugged and tightened. 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 man - ways 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 • J
