Pressure Relief Procedure

To avoid injury, relieve air and fluid pressure before checking, cleaning, or repairing the equipment.
The following is a basic pressure relief procedure. Be sure to follow the specific pressure relief procedure in your spray gun and/or fluid supply equipment manuals.
1.Close the main air
2.Trigger the gun or dispense valve and open any drain valves to relieve pressure.
Air Filter with Auto Drain 234402, Series B
To maintain maximum filtering efficiency and avoid excessive pressure drop, the filter must be kept clean. See Manual 309919 for cleaning and parts information.
Coalescer with Auto Drain 234397, Series B
It is recommended that Air Filter 234402 be 
installed upstream of the coalescing filter to
remove 3 micron and larger size particles and sep- arate large droplets of moisture from the air line.
CAUTION
Never let the liquid level in the bowl reach the base of the coalescing element.
Maintenance
• Relieve the pressure before cleaning, checking 
or repairing equipment. Follow Pressure
Relief Procedure, above.
•Check system at least once per shift to ensure proper drainage.
See Manual 309919 for operation, cleaning, and parts information.
