Seasoning Without a Fan Damper or AMS System
1. Remove the final filters.
2. Open the seasoning slide dampers.
3. Start the exhaust fan. Measure the face velocity at the enclosure
openings with a hand-held velometer. Record your readings.
4. Disconnect the powder feed hoses from the powder spray guns. Secure
the hose to the gun mounting bars. Do not point the hoses directly at
the cartridge filters.
5. Turn on the gun control units. Do not turn on the electrostatic voltage.
6. Adjust the flow-rate and atomizing air regulators on each gun control
unit to approximately 1.4 bar (20 psi). Raise or lower the pressures until
you obtain a light flow of powder from the feed hoses.
7. Take readings with the velometer until the face velocity decreases to
1
/
2
of the initial values recorded in step 3.
8. Adjust the pulse air pressure to 1.7 bar (25 psi) and start pulsing the
cartridge filters.
9. Continue to take velometer readings until the face velocity again
reaches
1
/
2
of the value recorded in step 3.
10. Adjust the pulse air pressure to 2.75 bar (40 psi).
11. Repeat step 9.
12. Adjust the pulse air pressure to 4.1 bar (60 psi). Adjust the gate valve
so the pressure decreases during a pulse and slowly builds back to
4.1 bar (60 psi) just before the next pulse. This will prevent starving the
powder pumps of air during pulses.
13. Close the seasoning slide gates. The face velocity should rise to
30 − 38 m/min (100 − 125 fpm) and remain steady.
14. Shut off the exhaust fan and install the final filters.
15. Check the face velocity. If it is below 30 m/min (100 fpm), contact your
Nordson representative.
