INSTALLATION INSTRUCTIONS 

 

1. 

Secure the filter unit frame 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.

 

‰

 

Check that safety switch is operational and functional

 

 

                
OPERATION INSTRUCTIONS 

 

1. 

The DCF-1600 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, 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). 

 

OPERATE EQUIPMENT ONLY WITH SUPPLIED SAFETY 
DEVICES  -WHICH ARE PROVEN TO BE CORRECTLY 
INSTALLED AND OPERATIONAL.  

 

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.
