8. On the atomizer speed select card, toggle the
“Enable” #1 switch down.
9. Stop the spinning bell by pressing the manual
brake button on the front panel of the test sta-
tion. Do not allow the turbine to spin in the re-
verse direction or it will damage unit.
4. Increase the shaping air pressure to 60 psig at
the gauge. Read the flow meter for airflow rate.
The rate for this pressure should be between
17 to 21 SCFM (481 SLPM to 594 SLPM).
(Note: This depends on length of shaping air
hose.)
5. Set the shaping air pressure back down to 0
psig and return the switch to the off position.
Turn off turbine.
6. Turn on “seal air” switch.
7. Increase the seal air pressure to 30 psig.
8. Select seal at flow rate select switch. Read
flow rate at the meter. The range of flow should
be between 8 SCFM to 12 SCFM (226 SLPM
to 340 SLPM).
9. Turn seal air switch off.

Shaping Air / Seal Air Test
1. Turn the shaping air switch to the “On” postion.
Set the shaping air pressure gage to read 25
psig by adjusting the regulator.
2. Set the atomizer speed select to 50,000 rpm.
Press the speed enter button. The turbine
should now begin spinning. This should be au-
dible.
3. Select the shaping air flow meter at the flow
rate select button. The flow rate should read
between 8 (226 SLPM) to 13 SCFM (368
SLPM) (Note: This depends on length of shap-
ing air hose.)

> If the On/Off switches for the
shaping and seal air are rapidly
turned on and off, the air flow meter
may de-couple and show a zero
reading. To recouple, leave the air
On/Off switch in the on position and
adjust the regulated air pressure
back to zero.
