4. Close the Vacuum Manifold Ball Valve
5. Release Vacuum from the entire AutoVap System
SLOWLY, open the vacuum release ball valve until the vacuum gauge reaches 0 HG.
CAUTION:
You must open the valve SLOWLY while looking at the vacuum gauge. If
you open the ball valve too quickly you risk pulling over crude oil into your nicely
recovered solvent.
6. Close the Vacuum Release Ball Valve
7. Open the Solvent Discharge Valve (See "4" on the figure above)
8. Locate the Air Chuck Assembly on the Residue Recovery Tank. The Ball Valve should be closed.
9. Attach an air compressor or N02 Generator to the Air Chuck Assembly [Located on the Residue Recovery
Tank]
If there is a pressure regulator on the compressor, set it between 5-15 PSI. You will not be using more than
5 PSI for this operation.
CAUTION: The Residue Recovery Tank is HOT, use caution when working near/around it.
10. Introduce Pressure to the system
Slowly open the Air Chuck Assembly ball valve to introduce pressure. Start with 1-3 PSI while monitoring
the pressure gauge.
WARNING: Do NOT pressurize the system above 15 PSI. If you do, the 15 PSI Pressure Relief Valve will
trigger. Be sure to have a collection vessel under the PRV blow off assembly.
A suggestion to ensure you do not over pressurize the system, is to toggle the Ball Valve on the Air Chuck
Assembly so that the system can only reach a maximum of 5 PSI.
The solvent should now be discharging from the Solvent Discharge Valve.
11. Verify the Solvent Recovery Tank is empty (view through sight glass)
12. Close the Ball Valve on the Air Check Assembly
13. Close the Solvent Discharge Valve.
STEP 4.1: RESTART THE SYSTEM
Now that you have discharged your solvent, you can restart the system.
1. Pull Vacuum on System
Open the Vacuum Manifold Ball Valve
Wait until the vacuum pressure reaches the desired setpoint (21-24 HG). You may need to adjust the
Vacuum Manifold Needle Valve Adjustment
2. Open the Feed Line Ball Valve
3. Start the Feed Pump
Press "Run" on the VFD Remote Control
