Preparation for Operation

Preparation for Operation

WARNING

Halogenated Hydrocarbon Hazard

Never use 1, 1, 1-trichloroethane, methylene chloride, other halogenated hydrocarbon solvents or fluids containing such solvents in this equipment. Such use could result in a serious chemical reaction, with the possibility of explosion, which could cause death, serious injury, and/or substantial property damage.

Consult your fluid suppliers to ensure that the fluids being used are compatible with aluminum parts.

WARNING

Fire, Explosion, and Electric Shock Hazard

When using the pressure cup with an electrostatic spray gun, connect the Graco

Grounded Air Supply Hose between the gun air fitting on the pressure cup and the gun's air inlet. The electrostatic gun air inlet has a left-hand thread. Connect the air supply hose ground wire to a true earth ground.

Prepare the paint or other coating according to the manufacturer’s instructions. Strain the paint through a fine nylon mesh bag, available at paint dealers. Fill the cup

(A) with paint and fasten the lid securely.

Connect the air (E) and fluid (D) hoses as shown in F IG .

1. On electrostatic guns, connect the air hose ground

wire (F) to a true earth ground.

Measure the resistance between the gun air inlet fitting and a true earth ground. The resistance must be less than 1 megohm.

Operation

Operation

One Quart Pressure Cup

WARNING

Pressurized Equipment Hazard

To reduce the risk of over-pressurizing the equipment, which could cause serious injury including splashing fluid in the eyes or on the skin, never exceed 20 psi (0.14 MPa, 1.4 bar) air pressure to the cup. The safety valve (9) is preset to relieve pressure at 20 psi (0.14 MPa, 1.4 bar). Do not alter the safety valve.

Pressure Relief Procedure

WARNING

Pressurized Equipment Hazard

The system pressure must be manually relieved to prevent the equipment from starting or spraying accidentally. To reduce the risk of an injury from accidental spray from the gun or splashing fluid, follow the Pressure Relief

Procedure whenever you:

• are instructed to relieve the pressure

• stop spraying

• check or service any of the system equipment

• or disconnect any of the system equipment.

1.

On electrostatic guns only, turn the ES ON/OFF valve OFF.

2.

Turn off the gun air regulator (4) and the cup air regulator (6).

3.

Trigger the gun into a grounded metal waste container to relieve the fluid pressure.

4.

Place the cup on a table and slowly release the clamp lever (3b) to bleed off pressure in the cup. Be sure to return the clamp lever to the locked position before turning the gun regulator on again.

Daily Setup

1.

Fill the cup (2) with fluid. Fasten the lid (3) securely.

2.

Turn on the main air supply.

3.

Set the gun air regulator (4) to 40 psi (0.28 MPa, 2.8 bar) while spraying. Push the knob in to lock the regulator, pull out to unlock.

4.

Set the cup air regulator (6) to 10 psi (.07 MPa, 0.7 bar). Push the knob in to lock the regulator, pull out to unlock.

5.

Spray a test panel. If the paint is not fully atomized, either decrease the fluid pressure using the cup air regulator or increase the setting of the gun air regulator.

To decrease the cup fluid pressure, turn the cup air regulator knob counterclockwise incrementally until you get the desired results.

Always use the lowest possible pressure needed to achieve the desired results.

WARNING

Pressurized Equipment Hazard

To reduce the risk of over-pressurizing the equipment, which could cause serious injury including splashing fluid in the eyes or on the skin, never exceed 50 psi (0.35 MPa, 3.5 bar) air pressure to the cup. The safety valve (9) is preset to relieve pressure at 50 psi (0.35 MPa, 3.5 bar). Do not alter the safety valve.

• check or service any of the system equipment

• or disconnect any of the system equipment.

1.

On electrostatic guns only, turn the ES ON/OFF valve OFF.

2.

Turn off the gun air regulator (2) and the cup air regulator (10).

3.

Open the pressure relief valve all the way (counterclockwise) to bleed off pressure in the cup.

4.

Trigger the gun into a grounded metal waste container to relieve the fluid pressure.

5.

Place the cup on a table and slowly unscrew the lid.

Daily Setup

1.

Fill the cup (1) with fluid. Fasten the lid securely.

2.

Turn on the main air supply.

3.

Turn the pressure relief valve fully clockwise.

4.

Set the gun air regulator (2) to 40 psi (0.28 MPa, 2.8 bar) while spraying. Push the knob in to lock the regulator, pull out to unlock.

5.

Set the cup air regulator (10) to 10 psi (.07 MPa, 0.7 bar). Push the knob in to lock the regulator, pull out to unlock.

6.

Spray a test panel. If the paint is not fully atomized, either decrease the fluid pressure using the cup air regulator or increase the setting of the gun air regulator.

To decrease the cup fluid pressure, turn the cup air regulator knob counterclockwise incrementally until you get the desired results.

Always use the lowest possible pressure needed to achieve the desired results.

Cleaning

Cleaning

One Quart Pressure Cup

CAUTION

To avoid damage to the air regulator diaphragms, do not clean the air regulators in a gun washer or use any cleaning method which allows solvent to enter the regulator.

1.

Relieve the pressure, page 4.

2.

Push the clamp lever (3b) to the unclamped posi-

tion, against the yoke. See F IG . 2.

3.

Twist the lid counterclockwise to disengage it.

Remove the lid.
