[. . . ] 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. [. . . ] 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. If the adjuster is moved rotationally, then the flow rate will be altered from the factory set point. Remove bonnet bolts (or knurled nut), lift bonnet straight up, and place in the clean area. Carefully tip body upside down so that the piston and spring slide out, and place both 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. [. . . ] This guarantee is valid for one year from date of shipment from its plant.
