[. . . ] 3) Before installing the controller, be sure to flush out the piping system to remove any foreign material such as dirt, scale, chips, etc. All controllers are constructed substantially, but pipe supports should be located so that the controller is not subject to mechanical load due to piping, or to the expansion or contraction of piping. The controller should be installed at a point in the pipe where it will be completely filled with liquid under all conditions of operation. On threaded connections, apply pipe thread compound sparingly to male threads only, so that surplus will not get inside the controller. START UP PROCEDURE Note: If the flow rate setting knob (or the adjuster bar) does not turn, loosen the dial lock screw. [. . . ] CAUTION: MAKE SURE THAT THE CONTROLLER IS RELIEVED OF PRESSURE BEFORE ATTEMPTING TO SERVICE OR CLEAN. TO CLEAN CONTROLLER CAUTION: in all cleaning operations, be very careful not to scratch, nick or mark any surfaces or edges. The controller operates by downward flowing liquid and is self cleaning for most liquids. Downflow design also will allow drainage on shutdown of many systems if discharge shutoff valve is closed after inlet shutoff valve. If installation includes proper shutoff and bypass valves, operate these and take controller off stream or control. Arrange a clean area where internal parts can be placed and kept free of dirt. Remove bonnet bolts, lift bonnet assembly straight up, remove body O-ring, and place both in the clean area. Slowly lift out the impeller, valve sleeve assembly, and spring, and place in the clean area. Remove the orifice cylinder clamp screws and lift out the orifice cylinder and place in the clean area. NOTE: Normally it is not necessary to remove the valve tube to clean it sufficiently. If it must be removed, follow instructions below "TO REMOVE VALVE TUBE". Thoroughly clean all parts that have been removed from the controller by immersing them in a suitable solvent. Clean and flush inside of flow controller body and the valve tube with the solvent, and drain. All surfaces, especially the metering orifice, the valve tube and integral valve ports, must be COMPLETELY CLEAN. Any dirt, sediment, coating or gummy residue must be completely removed. Replace orifice cylinder, and tighten clamp screws; replace the spring, impeller, and valve sleeve assembly on the valve sleeve. Make sure that the valve sleeve will slide freely on the valve tube with no sticking. Replace orifice sleeve, and make sure that orifice sleeve turns freely in both directions until it hits the vertical stop pin. Replace body O-ring, then lower the bonnet slowly, at the same time turning the flow rate setting knob until the key on the end of the adjuster shaft fits into the slots in the orifice sleeve, and the shoulder on the lower face of the bonnet fits into the body. When properly assembled, bonnet will seat squarely on the body all the way around. Place controller in service as specified under steps 2-7, "START UP PROCEDURE". TO REMOVE VALVE TUBE 1. If the valve tube must be removed, for cleaning or replacement, first remove all other internal parts of the controller. (Steps 1-7 above) Remove the valve tube screws, lift out the valve tube, and clean with solvent. [. . . ] Replace the bonnet, and put the controller in service by following Steps 2-7 listed under the heading "START UP PROCEDURE". 7.
