5. Apply the compressed air to the compressed air inlet of the
Aspirated Sampling Module at 20 to 25 psig (137 to 172 kPa).
6. Pull out the red locking ring and adjust the knob on the air
regulator to obtain a reading of 10 psig (90 kPa).
7. Notice the low flow indication on the front panel:
• If low flow indication is not ON, push in the air regulator red
locking ring to lock the regulator at this pressure.
• If the low flow indication is still ON, increase air pressure by
turning the knob until the indication turns OFF [do not exceed
15 psig (100 kPa)]. When indication turns OFF, push in the red
locking ring of the air regulator.
• If the low flow indication is still ON at 15 psig (100 kPa),
reduce the pressure below 10 psig (90 kPa) until the low flow
indication turns OFF.
