WED" <br /> V.'- <br /> DWG#1 1146-10 <br /> Removal of Waterflow Switch <br /> • To prevent accidental water damage,all control valves should be shut tight and the system completely drained before waterflow detectors are <br /> removed or replaced. <br /> • Turn off electrical power to the detector,then disconnect wiring. <br /> • Loosen nuts and remove U-bolts. <br /> • Gently lift the saddle far enough to get your fingers under it. With your fingers,roll the vane so it will fit through the hole while continuing <br /> to lift the waterflow detector saddle. <br /> • Lift detector clear of pipe. <br /> PRINTED IN USA MFG.#5401146-REV M PAGE 4 OF 4 <br /> 11/15 <br />
