SUPPLY AIR TO THE SYSTEM
6.1 ADJUSTMENTS AND OPERATIONS
1.
Turn the red valve on the air inlet valve/regulator/filter clockwise to the on position. Turn regulator that is on top of
the air filter to an air pressure between 40
-
100 psi (2.8
-
6.9 bar). Air pressures higher than this will shorten the life
of the pump.
2.
Adjust the regulated air pressures (regulators on front panel).
•
If applicable, depending on your spray system you may have anywhere from Liquid Pressure regulation only to
Liquid Pressure; Pump Air (preset); Atomizing Air (drop size); Fan Air (spray angle/pattern).
Each air control line is equipped with a manual air pressure regulator. The regulators can be adjusted by first pulling
up on the knob to unlock the regulator and then turning clockwise to increase and counterclockwise to decrease
the pressure.
When the proper air pressure is reached, press down on the knob on the regulator to lock it in place.
Note:
Your system is equipped with cylinder air for air actuated spray nozzles. Cylinder air pressure is equal to the
inlet air pressure to the system. It is not regulated; therefore, you must provide a minimum of 45 psi (3.1 bar) to the
system. It must be above 45 psi (3.1 bar) to actuate air actuated nozzles like Spraying Systems Co.

1/4JAU series.
5.
Adjust the Liquid Pressure regulator. For pump version ensure that the pump inlet air valve is in the
“
open
”
position. The regulator can be adjusted by first pulling up on the knob and then turning clockwise to increase and
counterclockwise to decrease the pressure. When the proper liquid pressure is reached, press down on the knob to
lock it in place.
