I1 1 <br />0 <br />Monitor Fitting <br />The monitoring fitting allows for the placement of <br />probe(s) to detect the presence of liquid in the <br />interstitial space. , <br />CE 1 FiberglassReservoir/Brine <br />Xerxes double wall tanks can be shipped with a <br />factory brine -filled interstice, which provides a <br />positive pressure hydrostatic monitoring system <br />to detect a leak. This system provides continuous <br />leak protection for both the primary and secondary <br />walls of the tank. In addition, Xerxes TRU-CHEK® <br />UL verified tank -rightness <br />test can be perform- <br />ed on all brine -filled <br />tanks. See page <br />16 for more C � <br />TRU-CHEK@ <br />details. l \\ <br />F Fiberglass Manways <br />Manways provide both access to the interior of the <br />tank as well as a location for service fittings. The <br />standard manway I.D. is 22-. Manways with 30" <br />and 36" I.D.'s are available on certain tanks. <br />Each manway is provided with a steel cover, with <br />plated bolts, nuts and washers, and a UL4isted <br />gasket. Manways are placed in standard locations <br />as shown on the standard tank drawings. <br />NPT Fittings <br />Steel NPT service fittings in the manway cover are <br />available in 2", 4", 6" and 8- half couplings. See <br />Standard Tank Data <br />on pages 7, 8 and 9 <br />for size and <br />quantities. z <br />Typical Manway Cover Fitting Configurations <br />A B C D <br />EIle <br />F G H <br />00 <br />Notes: <br />1.

When bolted to the manway, an extension <br />provides a watertight access to the tank interior. <br />Extensions are available in 22", 30" and 36" diam- <br />eters, and in two foot lengths or more. Extensions <br />include nuts, bolts, washers and a gasket. <br />
