Operation
Pressure Relief Procedure
Follow the Pressure Relief Procedure whenever
you see this symbol.
1. Turn off all the air to the spray gun except the cylin-
der air, which triggers the gun. If an air pilot fluid
regulator is used in the system, the air pressure is
needed at the regulator air inlet.
2. Turn off the fluid supply to the gun.
3. Trigger the gun into a grounded metal waste con-
tainer to relieve the fluid pressure.
4. If an air pilot fluid regulator is used, turn off the air
pressure at the regulator air inlet.
5. Relieve fluid pressure in the fluid supply equipment
as instructed in its instruction manual.
6. Open the pump drain valve and all other drain
valves in the system, having a waste container
ready to catch the drainage. Triggering the gun to
relieve pressure may not be sufficient. Leave the
drain valve open until you are ready to spray again
7. Close the bleed-type master air valve on the main
air supply line to shut off the air. Leave the valve
closed until you are ready to spray again.
8. If you suspect that the spray tip or hose is still
clogged or that pressure is not fully relieved after
following the steps above, very slowly loosen the
hose end coupling and relieve pressure gradually,
then loosen completely. Now clear the tip or hose
obstruction.
Startup
Check the following list daily, before starting to operate
the system, to help ensure you of safe, efficient opera-
tion.
Select a Spray Tip
The fluid output and pattern width depend on the size of
the spray tip, the fluid viscosity, and the fluid pressure.
Use the
Spray Tip Selection Chart
, page 45, as a
guide for selecting the appropriate spray tip for your
application.
This equipment stays pressurized until pressure is
manually relieved. To help prevent serious injury
from pressurized fluid, such as skin injection,
splashing fluid and moving parts, follow the Pressure
Relief Procedure when you stop spraying and before
cleaning, checking, or servicing the equipment.
All operators are properly trained to safely
operate an automatic electrostatic air-assisted
spray system as instructed in this manual.
All operators are trained in the
Pressure Relief
Procedure
on page 16.
The warning sign provided with the gun is
mounted in the spray area where it can be eas-
ily seen and read by all operators.
The system is thoroughly grounded and the
operator and all persons entering the spray
area are properly grounded. See
Grounding
on page 14.
The condition of the gun’s electrical compo-
nents has been checked as instructed in
Elec-
trical Tests
on page 22.
Ventilation fans are operating properly.
Workpiece hangers are clean and grounded.
All debris, including flammable fluids and rags,
is removed from the spray area.
All flammable fluids in the spray booth are in
approved, grounded containers.
All conductive objects in the spray area are
electrically grounded and the floor of the spray
area is electrically conductive and grounded.
The manifold exhaust tubes have been
checked for the presence of any fluid as
instructed in
Check for Fluid Leakage
on
page 21.
