5.6 PARTICULATE FILTER
The particulate filter (five micron) is included to prevent moisture and dirt from entering the
solenoid valve by way of the compressed air line. Excess moisture will condense inside the
attached polycarbonate bowl. The polycarbonate bowl water level can be viewed through
the slots of the metal bowl protector.
CAUTION: Regularly monitor the water level and do not allow it to go
above the maximum level indicator. If the water level exceeds the
maximum level indicated on the metal bowl cover, water may enter the
solenoid valve causing component failure.

DRAINING THE PARTICULATE FILTER BOWL
While the regulator is still under pressure, slowly rotate the drain valve on the bottom of
the bowl protector
counterclockwise
until water begins to drain. After all the water is
drained, rotate the drain valve
clockwise
to close the drain.
CAUTION: Ensure that the metal bowl protector does not rotate with the
drain valve. Hold the metal bowl protector in place while rotating the
drain valve if necessary.
REPLACING THE PARTICULATE FILTER ELEMENT
1.
Disconnect the compressed air line from the filter regulator assembly
2.
Open the drain valve on the bottom of the metal bowl protector—
This will ensure that no pressurized air
remains in the particulate filter.
3.
Rotate the metal bowl protector counterclockwise until it stops
4.
Pull the bowl protector downward until it releases from the particulate filter body
5.
Rotate the black plastic hex nut counterclockwise to unscrew it from the filter body until it is removed
6.
Remove the filter element and replace it with a clean new one
7.
Reinstall the hex nut and the metal bowl protector and close the drain valve
8.
Reconnect the compressed air line
5.7 VERIFYING THE FLUID RESERVOIR ASSEMBLY SET UP
Check that the following has been completed:
•
The air pressure switch, solenoid cable, and fluid level float switch are wired into the spray control panel
•
The air pressure switch is securely connected to the compressed air line, and the switch is securely
connected to the pump
•
The pump output line is securely connected to the fluid input on the electrostatic nozzle
