D) ATTACHING THE MANOMETER <br />D.1 - At this point, after the ALDP test, the interstice should still be holding vacuum. Maintain 20" of <br />Vacuum and slowly open ball valve to let fluid into the interstice until it exits the venturi assembly. <br />Visually check whether the fluid level reaches the top of the interstitial space. <br />Electronic liquid <br />level sensor is <br />installed inside <br />primary manometer <br />D.2- Cut the barb & ball valve assembly free by cutting the <br />tubing just below it and connect open end of tubing to the <br />bottom of the primary Manometer. <br />D.3- Cut the Tee and Gauge assembly free by cutting the <br />tubing just below it and connect open end of tubing to the <br />bottom of the atmospheric manometer. adjust atmospheric <br />manometer bracket so the manometer is in a position clear of <br />obstructions. <br />.4 - It is not uncommon for some interstitial fluid to be lost <br />while connecting the tubing to the primary manometer. This is <br />ok. Replace lost fluid by topping off manometer with interstitial <br />fluid until the liquid level reaches just 2 inches below the top <br />of manometer. <br />. - Hydrostatic Field Integrity Test <br />Mark the date and time of test and manometer level. Allow 1 hour <br />to look for a change in level. No change in level or visible leaking <br />means box passes test. <br />.6 -If interstitial test fluid changes its level more than 1/4", <br />visually look for any signs of leaking around fittings both interior and <br />exterior to sump. Pay special attention to field installed fittings. <br />NOTE: If you have completed the Air Integrity Test without <br />problems, and completed the Vacuum Hydrostatic Method of <br />filling and still have problems with sump integrity, Contact the <br />Factory. <br />.7 -If interstitial monitoring is required, install a California Listed <br />Hydrostatic Sensor (LG -113) using the sensor manufacturer's fitting. <br />Run the sensor cable through the cap assembly. The electronic <br />liquid level sensor should be set at the bottom of the primary (larger) <br />manometer reservoir. Follow your leak detector manufacturer's <br />installation instructions. Cover the manometer with cap and fasten <br />with wire and lead crimp seal. <br />P -Traps OK since vacuum fill method leaves no room for air. <br />11 ii -B8000 -9000 -DW -11B <br />
