Air Pressure and Air Flow Settings
(contd)
8. See Figure 3-3. Adjust the pulse-valve air pressure and volume.
a. Open the slide gate (4) on the side of the fan section to access the
pulse-valve air controls. Set the pulse valve regulator (1) to
345 − 413 kPa (50 − 60 psi). The valves will start pulsing. Watch the
pressure gauge (3). The pressure will drop when the valves open.
b. Adjust the gate valve (2) so the air pressure returns to 345 − 413 kPa
(50 − 60 psi) just before the next pulse. This adjustment will prevent
the powder pumps from being deprived of air during pulses.
9. Adjust the fan damper hand wheel (5) (Horizon 400 only) to obtain the
correct air flow through the enclosure. Refer to Fan Damper Adjustment
on page 3-6.
NOTE:
At this point, you can season your cartridge filters. Seasoning is not
required, but may extend the life of the filters. Refer to the Cartridge Filter
Seasoning section in this manual.
10. Start spraying powder. Adjust your application equipment settings to
obtain the coverage and film thickness desired.
11. Set the color module fluidizing air pressure to 0.7 bar (10 psi). The
recovered powder in the color module hoppers should boil gently.
Increase or decrease the fluidizing pressure as necessary.
