INSTALLATION AND MAINTENANCE DCF 800 TWINDOCUMENT #47556SPECIFICATIONSPiping Connections:• Inlet and Outlet: 2 inch NPTE, or option ordered• Purge: 1.5 inch NPTE, or option orderedFilter Element Type: Slotted, Defined Pore, or PerforatedFilter Body Volume: 4.0 US gallons (14.8 liters)Contaminant Purge Volume: 25 US ounces (0.74 liters)Design Pressure: Maximum Pressure: 150 PSIG (1035 kPa)Minimum Operation Pressure: 30 PSIG (207 kPa)Maximum Temperature:Defined by the elastomer and cleaning disc selectedMaximum Differential Pressure on filter element:Slotted or Perforated Element: 110 PSID (760 kPa)Defined Pore Elements: 50 PSID (345 kPa).INSTALLATION INSTRUCTIONS1. Secure the filter unit legs to a foundation.2. Attach the inlet and outlet connections to the interconnectingpiping (customer supplied). To properly support the filter unit,mount the filter in a vertical position. Take care to avoidexcessive nozzle loading at the filter connections. Consultyour pump manufacturer’s installation guide for minimum piperun length between the pump outlet and the inlet of the filterunit. NOTE: Isolation/block valves (supplied by others) arerequired on all process connections of the filter unit so thefilter can be isolated from the process liquid in the event thatservice is required. Pressure gauges (supplied by others) arealso recommended before and after the filter.3. Connect the drain line (customer supplied) to the filterunit’s purge valve. To avoid restricting purge flow the drainline should be: 1) the same or larger diameter as thepurge valve size, 2) as short as possible, and 3) at orlower than the height of the purge valve.4. See additional instructions for air and electrical installationinstructions.CHECKLISTComplete this checklist before operating the system. Verify that all process connections are secure and free of -leaks. -Element must be clean and free of damage.-Top and bottom element seals must be properly installed.-Proper element type must be used, as process requires.-Confirm that the gasket sealing the lid to the filterhousing is in good condition and properly installed.Disassembly of the unit may be required to verify above. Check Star Packing Wheel and tighten as required.Urethane seal requires only finger tight. Teflon requires atight fit with continued tightening adjustments as needed Verify that all lid bolts are tight. Verify that cleaning disc can be activated manually andautomatically if so equipped. Verify that purge valve is operable and normally in theclosed position for operation and start-up. Check that the purge line is directed in a suitable fashionto accept waste when purged.OPERATION INSTRUCTIONS1. The DCF-800 cleaning disc should stroke the elementclean to keep the differential pressure between the inletand outlet of the filter below 15 PSID. Stroking toofrequently will shorten the life of all wear components.Note: The burst strength of the filter elements is 110 PSIDdifferential pressures for slotted and perforated elements,and 50 PSID for defined pore.2. The filter unit is supplied with a valve used to purge thecontaminants from the housing. This valve should beopened before the collected contaminants exceed thepurge volume and causes a differential pressure increase.3. If filter element is removed from unit, avoid high-pressure washing from the outside of the element.This may force contaminants into the filter media andcause permanent blockage and/or element damage.4. Always pressurize the unit slowly on start-up andwatch for any leakage.5. The unit is equipped with a plug in the lid forplacement of overpressure vents, for use as an airrelease and/or connect for fluid filling of vessel.6. Monitoring of the differential pressure between inletand outlet pressures should be used to determinestroking and purging rates. Normal operation shouldexhibit low differential pressure that is maintainedthroughout.WARNING!MAXIMUM WORKING PRESSURE IS 150 PSIG (1035 kPa).CAUTION: PNEUMATIC CYLINDERS MAY MOVE FAST AND INAN UNEXPECTED MANNER—KEEP AREA DIRECTLY ABOVETHEM CLEAR.DO NOT STROKE CYLINDER WHEN BLOCK VALVES ARECLOSED.THIS FILTER UNIT MAY BE UNDER PRESSURE – EXTREMECARE MUST BE TAKEN WHEN INSPECTING OR SERVICINGTHE EQUIPMENT.
