[. . . ] INSTALLATION & SERVICE INSTRUCTIONS FOR KATES FLOW CONTROLLER MODELS 50FB, 50FB-UHRA IMPORTANT THE KATES FLOW RATE CONTROLLER IS DESIGNED TO ACCURATELY REGULATE FLOW RATES AND IS PRECISION BUILT WITH EXACTING TOLERANCES AND FINISHES. TO INSURE SATISFACTORY PERFORMANCE, THE REGULATED FLUID MUST BE CLEAN AND FREE OF DIRT OR SOLIDS. THE INSTALLATION OF A 20 MICRON FILTER IS RECOMMENDED JUST UPSTREAM OF THE CONTROLLER. [. . . ] On threaded connections, apply pipe thread compound sparingly to male threads only so that surplus will not get inside the controller and cause "sticking" or prevent operation. START UP PRODEDURE 1. Place controller "on stream" by opening upstream and downstream shutoff valves and slowly closing the bypass valve around the controller. When normal fluid temperature is above room temperature, especially with viscous fluids, there may be a "warming up" period until the controller reaches the same temperature as the fluid. During this warming up period, the controller may be somewhat sluggish in action. If desired, this warming up period may be eliminated by the use of a heating coil or jacket. SERVICE INSTRUCTIONS The Kates Flow Rate Controller has only one moving element, and is designed so that there are no complex linkages, delicate bearings, or any failure-prone components. Therefore, occasional cleaning may be the only servicing the controller will require. 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. If installation includes proper shutoff and bypass valves, operate these and take the controller off stream or control. Arrange a clean area where internal trim parts can be placed and kept free of lint or grit. Do not remove the hex nut and the socket head cap screw in the center of the adjuster orifice assembly. Remove the screws holding the adjuster orifice assembly in the body, pull the assembly out of the body, and place in the clean area. Remove end plug, spring, piston, and place all in the clean area. 5. 6. 9. Thoroughly clean all the parts that have been removed from the controller by immersing them in a suitable solvent. Thoroughly clean and flush inside of controller body with the solvent, and drain. Because of the closely fitted parts, it is VERY IMPORTANT that all parts and surfaces, including valve ports, be COMPLETELY CLEAN.
