PLASTEE - ®ELUTRO :" Double-wau <br /> APPENDIX A Tank <br /> INSTALLATION SITE TESTING PROCEDURES <br /> Option /1: EXTERIOR HOUDAY TEST Option i2: VACUUM TEST INTERSTICE <br /> Prior to arrival of the Elutron® tank at the installation The Elutron® tank may be delivered with an interstitial vacuum established at <br /> site, coordinate with the Elutron® manufacturer to have the factory. The delivery document will state the vacuum gauge reading required <br /> a 12,500 volt holiday test performed using a Tucker-Rasor, for acceptance at the delivery location. Record the vacuum gauge reading on the <br /> Model APW, tester. Any pinholes detected must be delivery document when the tank is delivered. If the vacuum gauge has decreased <br /> repaired using the Plasteel® sealing kit materials. Re-test from the vacuum gauge reading listed for acceptance on the delivery document, <br /> and repair until tank is pinhole free. This test must be call the factory for further instructions. If an interstitial vacuum is to be established <br /> performed by a person qualified by the Elutron® tank at the installation, follow the instructions in Appendix 13, Interstitial Vacuum Test. <br /> manufacturer. Do NOT apply a vacuum to the primary tank,D MAY OCCUR. <br /> Option /3• PRESSURE TEST INTERSTICE <br /> If a field pressure test is required,set-up test equipment per the schematic diagram and precisely follow the test procedures listed. <br /> CAUTION: DAMAGE TO TANK MAY OCCUR IF PRESSURE IN THE <br /> INTEFISTICE EXCEEDS 2 PSIG ABOVEGROUND. <br /> Step 1. Ensure gauges are accurately calibrated. B. Observe G2 for 30 minutes. G2 should remain at <br /> 11/2- 2 psig. (Call factory H G2 decreases to zero.) <br /> 2. Ensure all connections are leak tight. <br /> 9. Open V3, vent interstice, G2 to read zero. <br /> 3. Close V2, open V3, G2 should read zero. <br /> 10. Open V1, vent primary tank, G1 to read zero. <br /> 4. Open V1, pressurize primary tank until G1 reads Test complete. <br /> 3-5 psig, close V1.Disconnect air source. <br /> NOTE: If the Elutron0 tank is covered with backfill, you may <br /> 5.
