OPERATION

WARNING

Pressure 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 off 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 off 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.Turn off 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, efficient 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 differ- ent nozzle and air cap combination, use instruction manual 307–803 to select the appropriate fluid nozzle and air cap.

Gun Functions

The gun functions include the following:

SFluid Trigger (only)

SSpray (properly timed on/off sequence of fan air, atom air, and paint)

STurbine Air

SVoltage Select

Activating the Fluid Trigger Only

To activate the fluid trigger alone, first relieve the air pres- sure to the trigger module, then shut off the air supply to the ATOM and FAN 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 efficien- cy, always use the lowest air pressure possible.

NOTE: See the Spray Pattern Troubleshooting Chart

on page 13 to correct spray pattern problems.
