Selection Charts
Proper Needle/Nozzle Selection
The spray gun's needle/nozzle kits range in size to provide different fluid flow rates.
As a general guideline, use the fluid nozzle that will give the required flow with the needle fully triggered at a fluid pressure of 5-20 psi (0.035 MPa, 3.5 bar - 0.14 MPa. 14 bar)
For low flow rates or light viscosity fluid, select the smaller nozzle sizes.
For high flow rates or high viscosity fluid, select the larger nozzle sizes.
For thicker, abrasive fluids, hardened SST needle tips and nozzles are recommended.
Gun Selection
HVLP Guns
An HVLP gun is a high transfer efficiency gun that limits the air pressure at the air cap to 10 psi (0.07 MPa, 0.7 bar) maximum. In some areas, an HVLP gun is required for compliance with environmental standards.
Compliant Guns
A compliant gun is a high transfer efficiency gun that has been tested to have a transfer efficiency greater than or equal to HVLP guns. In addition, the compliant air cap consumes much less air than the HVLP air cap.
The Graco compliant guns have no restrictions on air cap pressures, but the gun inlet pressure must remain under 30 psi (0.21 MPa, 2.1 bar) to remain in compliance.
Airspray Guns
An airspray gun has excellent atomization and high production rates typically with some reduction in transfer efficiency.

Installation
Installation
The Automatic XT spray guns were designed to produce the highest quality finish with today's fluids as well as the low V.O.C. (volatile organic compound) fluids of tomorrow.
This spray gun can spray most coatings or finishes currently being used for automotive, industrial, aerospace, marine, wood, plastic and architectural applications, while easily operating from paint delivery systems, such as pressure pots or remote pumps for production line operation.
The air regulator must have a minimum air flow capacity of 30 scfm at 100 psi (0.7 MPa, 7 bar) air pressure.

If your regulated air source does not have a filter, install an air filter (G) on each air line to ensure a dry, clean air supply to the gun. Dirt and moisture can ruin the appearance of your finished work-
Install a bleed type air shutoff valve (E) on each gun air supply line, downstream of the gun air regulator, to shut off air to the gun.
Connect Fluid Hose
Before connecting the fluid line, blow it out with air and flush it with solvent. Use solvent that is compatible with the fluid to be sprayed.
Install a fluid regulator (L) on the fluid line to control
fluid pressure to the gun. See F IG . 9.
Install a fluid shutoff valve (M) to shut off the fluid
supply to the gun. See F IG . 9.
Filter the fluid line of coarse particles and sediment to avoid clogging the fluid nozzle and causing finishing defects.
1.
For manifolds with a separate ATOM and FAN port, the gun cylinder, fan, and atomization air must be supplied and regulated separately. For the manual fan valve manifold, only one supply line is required for both atomization and fan air.
The gun atomizing and fan air inlets are 3/8 in. O.D. tubing. The cylinder air inlet accepts 1/4 in. (6.3 mm) O.D. tubing. Use 3/8 in. (9.5 mm) O.D. tubing for fan and atomization air to minimize excessive pressure drop in the hoses.
1.
Connect the fluid supply hose (J) to the gun fluid
inlet (S) 1/4 npsm thread. See F IG . 10.
2.
Connect the other end of the fluid hose (J) to a regu-
lated fluid supply outlet (M). See F IG . 9.
3.
In a circulating system, connect a grounded fluid
return hose to the gun fluid outlet (T). See F IG . 10.
In a non-circulating system, remove the gun fluid outlet fitting (T) and plug the outlet port with the pipe
2.
Connect each air hose (D) to a regulated air supply line (H).

Position Air Cap
Air caps are factory-set with the alignment pin (A) set to a vertical spray pattern. To change the air cap to a horizontal spray pattern, use a needle nos pliers to unscrew the alignment pin (A) and relocate it to the horizontal spray pattern hole. When relocating the pin use low strength thread locker. Torque to 1.5-2.5 in-lb (0.2-0.3
N•m). Do not overtighten. Refer to F IG . 11.

Setup
Adjust Spray Pattern
A larger fluid nozzle at a reduced fluid pressure will maintain the same flow rate, but the fluid stream
(velocity) will slow down. When air is applied, this allows air to act on the fluid longer and improve the atomization.
Do not exceed 100 psi (0.7 MPa, 7 bar) maximum fluid and air pressure. Higher pressures can cause parts to rupture and result in serious injury.
The spray gun fluid flow is controlled by the fluid pressure regulator and the fluid control knob. Use the fluid pressure regulator to adjust the general fluid flow and the fluid control knob to make precise fluid flow adjustments.
CAUTION
Use caution when operating the fluid control valve near the closed position. The plastic needle tip may be damaged if forced too hard against the nozzle seat by the fluid control valve.
Follow these steps to establish the correct fluid flow and air flow:
1.
To achieve desired flow, adjust the fluid flow using the fluid pressure regulator (L) installed in the gun fluid line. Typical industrial flow rates will vary with regulator pressures from 5 to 30 psi (34 to 210 kPa,
0.3 to 2.1 bar). If the fluid pressure is too low at the desired flow rate, install a smaller nozzle. If the fluid pressure is too high, install a larger nozzle.
For spray guns equipped with the fluid control knob, you can make flow rate changes at the spray gun.
Rotate the fluid control knob clockwise to reduce the flow.
2.
Using the air pressure regulator (F), set the fan and atomizing air supply pressure per Table 1. Use these suggested settings as a starting point.

HVLP and Compliant Gun Limits
HVLP Guns: local laws may limit the maximum pressure to 10 psi (70 kPa, 0.7 bar) at the air cap for compliance. 35 psi (25 kPa, 2.5 bar) inlet air yields 10 psi (70 kPa, 0.7 bar) at the air cap. To measure pressure at the air cap, use the accessory
tapped air cap. See Accessories, page 33.
Compliant Guns: the maximum inlet pressure to the manifold is 30 psi atomizing air.

3.
Test the spray pattern atomization while keeping the gun a consistent distance, about 6 to 8 inches (150 to 200 mm), from the test piece.
Check the atomization quality. Increase the gun atomizing air supply pressure with the air pressure regulator in 5 psi (34 kPa, 0.3 bar) increments until you obtain the desired atomization.
For the best transfer efficiency, use the lowest setting needed to achieve desired finish quality.
4.
If the spray pattern is too wide or split, reduce the fan air pressure (or slightly close the fan adjustment valve on manifold 288223).
To further control the spray pattern of airspray guns
only, use an alternate air cap. For a list of available
air caps, refer to Accessories, page 33.
Reducing the fan air pressure to 0 psi (or fully closing the fan adjustment valve) will produce a round pattern.

Operation
Operation
Pressure Relief Procedure
1.
Turn off all bleed type air valves and all other air and fluid supplies to the gun.
2.
Trigger the gun into a grounded metal waste container to relieve air and fluid pressure.
To achieve best results when applying fluid:
• Keep gun perpendicular and 6 to 8 in. (150 to 200 mm) from object being sprayed.
• Use smooth, parallel strokes across surface to be sprayed with 50% overlap.
Incorrect
TI8174a
F IG . 14: Pressure Relief
Apply Fluid
The spray gun has a built-in lead and lag operation.
When triggered, the gun begins emitting air before the fluid is discharged. When the trigger actuation air is stopped, the fluid stops before the air flow stops. This helps ensure that the spray is atomized and prevents fluid buildup on the air cap and tip.
Adjust the system control device, if it is automatic, so the gun starts spraying just before meeting the part and stops as soon as the part has passed. Keep the gun a consistent distance, 6 to 8 in. (150 to 200 mm), from the surface of the object being sprayed.
