VII. System Maintenance Procedures (continued)
R. Outlet Section Maintenance
This procedure will detail the isolation and evacuation procedures required for the
maintenance or replacement of any of the outlet components: Liquid Pump Particulate
Filter F6, Liquid Pump LP1, Liquid Pump LP2 and Outlet Solenoid Valve SV-4. Refer to
figue-13 in section-VII.K.
Machine Evacuation Procedure
Required Materials:
AGENT Vapor Recovery Pump
Vacuum Pump
Leak Detector Fluid
Evacuated AGENT Storage Cylinder
Clean Dry Nitrogen Source regulated to 200 psi
Vacuum Gauge
¼” Refrigeration Service Hoses
Straight Blade Screwdriver
Wrench Set
NOTE: All plumbing connections to the various access valves of the machine require
SAE ¼” x 45 Female Flare connectors. Access valve locations designated by “AV” will
require valve core depressors. Standard ¼” refrigeration service hoses will mate to all
of the access valves and may be used to simplify all plumbing connections.
1. Place the front panel Power Switch to the OFF position and disconnect Main Electrical
Power from the Machine.
2. Remove the lower left side panel of the machine
3. Remove the valve cover from the Process Outlet Manual Valve MV-4. Support the
Large Hex of the valve with a wrench and rotate the center bar of the valve clockwise to
close the valve.
4. Close the receiving container valves.
5. Disconnect the receiving container from the machine and cap the Outlet Port of the
machine.
6. Recover the trapped AGENT from the machine pump plumbing through the AV-5
access valve.
7. Maintenance or replacement of the Liquid Pump Particulate Filter F6, Liquid Pump LP1,
Liquid Pump LP2 and Outlet Solenoid Valve SV-4 may now be performed. Leak test
any plumbing connections using 200 psi of nitrogen gas through the AV-5 access valve
and the leak detector fluid. Depressurize the plumbing after leak testing through the AV-
5 access valve.
8 To Clean the Liquid Pump Particulate Filter: hold the body of the filter with an adjustable
wrench and rotate the large hex of the filter counterclockwise. Unscrew the hex and
remove the filter screen. Empty the filter screen. Replace the filter screen and large hex
back to the filter body and tighten securely.
9. Evacuate the pump plumbing to a minimum 1000-micron vacuum level using a vacuum
pump through the AV-5 access valve then disconnect the vacuum pump and cap the
AV-5 access valve.
10. Open the Process Outlet Manual Valve MV-4.
11. Replace the lower left side panel of the machine
