V. System Operations and Controls
B. Initial System Start-Up Procedure (continued)
6. Nitrogen Gas Purge.
NOTE: The machine is shipped with a small amount of nitrogen gas pressurizing the
system. Clear the nitrogen from the system by performing the following steps (a)
through (e). When charging the machine after system maintenance evacuation
procedures these steps are NOT TO BE PERFORMED unless nitrogen gas has been
added to the system.
a. Place the Inlet Valve switch to the ON position.
b. Place the N2 Valve switch to the ON position.
c. Observe the pressure controller display. Wait for the pressure to drop to a 15 to 16
PSI display.
d. Place the Inlet Valve switch to the AUTO position.
e. Place the N2 Valve switch to the AUTO position.
7. Install the agent source container to the machine as per section-IV.G. of this manual.
8. Open the valve of the source container to allow agent to flow to the Manual Inlet Valve
of the machine.
NOTE: If the inlet plumbing requires repairs the trapped Agent in the plumbing may
be drawn into the machine by first closing the outlet valve of the source container.
Then open the Manual Inlet Valve of the machine followed by placing the Inlet Valve
Switch to the ON position. The Inlet Pressure Gauge of the machine should drop to
zero pressure. Close the Manual Inlet Valve and place the Inlet Valve Switch to the
AUTO position. Repair the leak points and begin again with step-7.
9. Open the Manual Inlet Valve of the Machine.
10. Place the Inlet Valve Switch to the ON position. AGENT will now flow into the
machine.
11. Observe the Moisture Indicator Sight Glass on the front panel. The sight glass should
initially appear empty then fill with the incoming AGENT liquid.
12. Observe the Agent Liquid Level Lamps on the front panel. When the Low Level
Lamp illuminates: Close the valve of the source container to stop the flow of
agent to the machine.
13. Observe the Moisture Indicator Sight Glass and the Inlet Pressure Gauge on the front
panel. When the sight glass once again appears empty and the pressure is below 100
psi for 1301 and FE25 or below 30 psi for FM200 or below 15 psi for 1211: perform
step-14.
14. Place the Inlet Compressor Switch to the ON position. The vapor compressor will
begin to evacuate the remaining vapor from the inlet plumbing connected to the source
container.
15. Observe the Inlet Pressure Gauge of the front panel. When the pressure gauge
indicates a vacuum level, continue with step-16.
16. Place the Inlet Compressor Switch to the AUTO position.
17. Place the Inlet Valve Switch to the AUTO position.
18. Close the Manual Inlet Valve of the machine.
The machine is now primed. The source container may be disconnected from the
machine, or after reviewing sections-V.C: Inlet Pressure Switch Function and Adjustment
and sections-V.D: Automatic System Operation of this manual. The source container can
be completely emptied and evacuated into the machine in either the automatic mode or
manually.
