Since the actual differential pressure generated is only 237 p.s.i., very <br />little drift should be measured. . <br /> <br />PROCEDURE <br /> <br />. ~ <br /> <br />L <br />h <br />~ <br /> <br />WARNING -1~t.:::SlI~~:@..f.~;II:!!I:I~I!::i1[i~il.~;~t($.t.~Ii;Ii.'ii;1I.Q..~I!Bii <br />i@iI1Iiilli~ilt~~~a~~lyl:liiiRri~gtg;i,-gi. <br /> <br />CAUTION - Disengage ring-follower hanger <br /> <br />H in NEUTRAL, E and F are CLOSED. <br /> <br />OPEN E~ and D to test ring-follower #1. <br /> <br />OPEN ring follower #1 by shifting G to OPEN until fully opened. <br /> <br />Begin ciosing the ring-follower by shifting G to CLOSE. <br /> <br />CLOSE D.
