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 /> OD.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 /> 0 <br /> Q 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 /> DA - 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 /> Cut off barb fluid until the liquid level reaches just 2 inches below the top <br /> & ball valve of manometer. <br /> assembly D.5 - 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 /> D.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 /> `m Factory. <br /> s <br /> a <br /> cno Ec <br /> E c m D.7 - If interstitial monitoring is required, install a California Listed <br /> ca Q <br /> a 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 /> tinstalled <br /> ronic liquid with wire and lead crimp seal. <br /> l sensor is <br /> inside P-Traps OK since vacuum fill method leaves no room for air. <br /> manometer <br /> 11 ii-B8000-9000-DW-11B <br />
