Relief Procedure
To
reduce the risk
of serious bodily injury
, including
splashing in the eyes or on the skin, injury from
moving parts or electrostatic shock, always follow
this
procedure when shutting of
f the system, when
checking
or servicing any part of the spray system,
when
installing, cleaning or changing fluid nozzles,
and
whenever you stop spraying.
1. Turn
of
f the air to the control module, except for
the
manifold air
. If the air pilot fluid regulator is
used,
air pressure is needed at the regulator air
inlet
to relieve pressure in the fluid line.
2. T
urn of
f the fluid supply to the gun.
3. Trigger the gun into a grounded metal waste
container
to relieve fluid pressure.
4. Open the pump drain valve, having a waste
container
ready to catch the drainage.
5. Leave
the pump drain valve open until you are
ready
to spray again.
WARNING
If any fluid leakage from the gun is detected,
stop
spraying
IMMEDIATELY!
Fluid leakage into
the
gun shroud could cause fire or explosion and re
-
sult in serious bodily injury and property damage.
See
Check for Fluid Leakage
, page 12.
Operating Checklist
Check
the following list daily
, before starting to operate
the
system,
to help ensure you of safe, ef
ficient operation.
1. Be sure all operators are properly trained to
safely operate an automatic electrostatic air
spray
system.
2. Be
sure all operators are trained how to prop
-
erly
and completely relieve system pressure.
3. Be sure the system is thoroughly grounded.
See FIRE, EXPLOSION OR ELECTRO-
STATIC SHOCK HAZARD on page 3, and
Check the Electrical Grounding on
page 8.
4. Be
sure the operator and all persons entering
the
spray area are properly grounded by
wear
-
ing shoes with conductive soles or personal
grounding
straps.
5. Be sure ventilation fans are operating
properly.
6. Be
sure the workpiece hangers
are clean and
grounded. Contact points must be sharp
points
or knife edges.
7. Be sure all refuse is removed from the spray
booth.
8. Be sure all flammable liquids in the spray
booth
are in approved, grounded containers.
9. Be sure all conductive objects in the spray
area
are electrically
grounded and the floor of
the spray area is electrically conductive and
grounded.
10. Be sure to check the manifold exhaust tubes
for the presence of any fluid as instructed in
Check for Fluid Leakage
, page 12
.
Selecting a Fluid Nozzle and Air Cap
This
gun is supplied with fluid nozzle 185–158 (1.5 mm)
and
air cap 177–033. If your application requires a
dif
fer-
ent nozzle and air cap combination, use instruction
manual 307–803 to select the appropriate fluid nozzle
and
air cap.

Activating the Fluid Trigger Only
To
activate the fluid trigger alone, first relieve the air
pres
-
sure
to the trigger module, then shut of
f the air supply to
the
A
T
OM and F
AN air lines. Apply 50 psi (3.5 bar) mini
-
mum
air pressure to the CYL air supply line to activate the
gun’s
fluid trigger
.
Adjusting the Spray Pattern
Follow the steps below to establish the correct fluid
flow
and
air flow
.
DO NOT
turn the turbine air (electrostatics)
on
yet.
1. Adjust the fluid flow with the fluid line’ s pressure
regulator.
2. Rotate
the air cap for the desired spray pattern.
3. Use
an air pressure regulator to adjust the degree of
atomization
and pattern width. For the most ef
ficien-
cy,
always use the lowest air pressure possible.
NOTE:
See the
Spray Pattern T
roubleshooting Chart
on
page 13 to correct spray pattern problems.
