User manual WA KATES FM12

[. . . ] EQUALLY IMPORTANT: WHEN DIS-ASSEMBLING, SERVICING, OR CLEANING THE CONTROLLER, THE INTERNAL PARTS MUST BE HANDLED WITH CARE TO PREVENT DAMAGING THE SURFACE FINISH IN ANY WAY. OPERATION OF A KATES ADJUSTABLE FLOW RATE CONTROLLER THAT IS SUPPLIED BY A POSITIVE DISPLACEMENT PUMP, WILL BE SATISFACTORY ONLY IF A PRESSURE-RELIEVING VALVE IS CONNECTED BETWEEN THE PUMP AND THE CONTROLLER. THIS IS TO BYPASS EXCESS FLUID BACK TO THE FLUID SOURCE, OR TO THE INTAKE OF THE PUMP. INSTALLATION 1. [. . . ] 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. Remove bonnet bolts using a ¼" allen wrench, lift bonnet assembly straight up, remove body O-ring, and place all in the clean area. Using a ¾" socket wrench, only loosen orifice plug in the valve cylinder, do not remove. Remove the valve cylinder assembly from the body using a 7/8" socket wrench. CAUTION: Improper removal of orifice plug from the valve cylinder assembly may result in an injury, or may damage the part. Place the orifice plug, spring, piston, and valve cylinder in the clean area. 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. Any dirt, sediment, coating or gummy residue must be completely removed. CAUTION: in all cleaning operations, be very careful not to scratch, nick or mark any surfaces or edges.
