Design Pressure: Maximum Pressure: 150 PSIG (1035 kPa)
Minimum Operation Pressure: 30 PSIG (207 kPa)
Maximum Temperature:
Defined by the elastomer and cleaning disc selected
Maximum Differential Pressure on filter element:
Slotted or Perforated Element: 110 PSID (760 kPa)
Defined Pore Elements: 50 PSID (345 kPa).
INSTALLATION INSTRUCTIONS
1. Secure the filter unit legs to a foundation.
2. Attach the inlet and outlet connections to the interconnecting
piping (customer supplied). To properly support the filter unit,
mount the filter in a vertical position. Take care to avoid
excessive nozzle loading at the filter connections. Consult
your pump manufacturer’s installation guide for minimum pipe
run length between the pump outlet and the inlet of the filter
unit. NOTE: Isolation/block valves (supplied by others) are
required on all process connections of the filter unit so the
filter can be isolated from the process liquid in the event that
service is required. Pressure gauges (supplied by others) are
also recommended before and after the filter.
3. Connect the drain line (customer supplied) to the filter
unit’s purge valve. To avoid restricting purge flow the drain
line should be: 1) the same or larger diameter as the
purge valve size, 2) as short as possible, and 3) at or
lower than the height of the purge valve.
4. See additional instructions for air and electrical installation
instructions.
CHECKLIST
Complete 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 filter
housing 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 a
tight fit with continued tightening adjustments as needed
Verify that all lid bolts are tight.
Verify that cleaning disc can be activated manually and
automatically if so equipped.
Verify that purge valve is operable and normally in the
closed position for operation and start-up.
Check that the purge line is directed in a suitable fashion
to accept waste when purged.
OPERATION INSTRUCTIONS
1. The DCF-800 cleaning disc should stroke the element
clean to keep the differential pressure between the inlet
and outlet of the filter below 15 PSID. Stroking too
frequently will shorten the life of all wear components.
Note: The burst strength of the filter elements is 110 PSID
differential pressures for slotted and perforated elements,
and 50 PSID for defined pore.
2. The filter unit is supplied with a valve used to purge the
contaminants from the housing. This valve should be
opened before the collected contaminants exceed the
purge 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 and
cause permanent blockage and/or element damage.
4. Always pressurize the unit slowly on start-up and
watch for any leakage.
5. The unit is equipped with a plug in the lid for
placement of overpressure vents, for use as an air
release and/or connect for fluid filling of vessel.
6. Monitoring of the differential pressure between inlet
and outlet pressures should be used to determine
stroking and purging rates. Normal operation should
exhibit low differential pressure that is maintained
throughout.
WARNING!
MAXIMUM WORKING PRESSURE IS 150 PSIG (1035 kPa).
CAUTION: PNEUMATIC CYLINDERS MAY MOVE FAST AND IN
AN UNEXPECTED MANNER—KEEP AREA DIRECTLY ABOVE
THEM CLEAR.
DO NOT STROKE CYLINDER WHEN BLOCK VALVES ARE
CLOSED.
THIS FILTER UNIT MAY BE UNDER PRESSURE – EXTREME
CARE MUST BE TAKEN WHEN INSPECTING OR SERVICING
THE EQUIPMENT.

MAINTENANCE
To service unit: Isolate it from the process air and electric supply
using proper lockout tagout plant procedures. De-pressurize and de-
energize all sources of power.
•Disconnect all remote airlines running to the assembly, marking
all airlines before removing. Loosen the 4 swing bolts from the
lid and remove the lid assembly with cleaning disc attached.
•Inspect cleaning disc for excessive wear. If replacement is
required see the spare parts drawing supplied with the unit and
select the appropriate repair kit or contact Ronningen-Petter
Customer Service. Refer to instructions included with disc
repair kit.
•Remove element by using the element removal handle
supplied with the unit (see the drawing below). Inspect element
for damage and plugging. Clean or replace as needed.
Remove lower “O” ring and clean.
•To reassemble, flush housing removing all dirt and
contaminant. Clean and inspect all “O” rings for damage,
replace as needed. Place lower “O” ring in the bottom of the
housing making sure it lays flat and is centered on the ID of the
housing (Attach top element “O” ring as needed.) Replace
clean element in the housing with the handles up.
•To replace the lid and cleaning disc assembly, extend the
center shaft to allow compression of the cleaning disc with the
compression pliers supplied with the unit. Place the Lid “O” ring
on the upper body flange checking to see that it is laying flat
and centered on the housing. Insert the cleaning disc in the
element and release the pliers and seat the lid double-checking
the placement of the lid “O” ring. Replace the lid bolts and
tighten.
•Reconnect the airlines
•Place the system back online using proper plant procedures.
For maintenance of other items such as lid seals, actuators, and
valves, see instructions supplied with repair kits.
