VII. System Maintenance Procedures (continued)
I. Inlet Particulate Filter Element Replacement
NOTE: Filter replacement is most easily accomplished just after the machine stops
processing automatically and the empty source container is disconnected. If the source
container is not empty perform section-V.E: Disconnecting the Source Container
When it is not empty; before starting this procedure.
Figures 10 and 11 will detail the location and replacement of the inlet particulate filter
element. The inlet particulate filter element should be replaced after every 10000 pounds
of AGENT processed. The inlet particulate filter element will require early replacement if
the red indicating button of the filter is extended out past the indicator ring.
Replacement Procedure
Required Materials:
Vacuum Pump
Clean Dry Nitrogen Gas
Cloth Rags
Vacuum Gauge
Pressure Gauge
¼” Refrigeration Service Hoses
Leak Detector Fluid
1. Verify the Manual Inlet and Inlet Evacuation Valves are Closed.
2. Place the front panel System Power Switch to the On position.
3. Place the front panel Inlet Valve Switch to the On position.
4. Place the front panel Inlet Compressor Switch to the On position.
5. Wait for the front panel Pressure Gauge to indicate a vacuum condition.
6. Place the front panel Inlet Compressor Switch to the AUTO position.
7. Place the front panel Inlet Valve Switch to the AUTO position.
8. Place the machine System Power Switch to the Off position.
9. Disconnect main electrical power from the machine.
10. Open the filter maintenance access door on the top-right corner of the front control
panel black hood.
11. Locate the filter maintenance manual ball valve MV-2 and close the valve. The valve
will be closed when the handle of the valve is at a 90 angle with the body of the valve.
Refer to figure-11 for component locations.
12. Open and then Close the Manual Inlet Valve to release the vacuum.
13. Remove the aluminum housing of the inlet particulate filter by rotating it
counterclockwise and pulling it straight away from the filter head.
14. Clean the interior of the filter housing and head using a soft brush or cloth.
15. Remove the filter element by pulling it straight away from the filter head.
16. Install a new filter element; part number A4-05-2500-00-1, as depicted by figure-10.
17. Verify the integrity of the filter head O-ring and backup ring seals. Replace the seals
as required using O-ring, A4-04-7060-00-0, and backup ring, A4-04-7060-00-1.
18. Install the aluminum housing onto the filter head and over the filter element by
threading in a clockwise rotation.
19. Remove the cap from the inlet valve of the machine and connect a source of clean dry
nitrogen, regulated from 200 to 250 psi, to the Manual Inlet Valve. The nitrogen supply
to the machine may be used see section-VII.H.
20. Open the Manual Inlet Valve to pressurize the inlet components with the nitrogen.
