WARNING

PRESSURIZED FLUID HAZARD

Spray from the gun, hose leaks or ruptured components can splash fluid in the eyes or on the skin and cause serious injury.

D Do not stop or deflect fluid leaks with your hand, body, glove or rag. D Follow the Pressure Relief Procedure on page 9 whenever you: are instructed to relieve pres-

sure; stop spraying; clean, check, or service the equipment; or install or clean the spray nozzle.

Warning Symbol

WARNING

This symbol alerts you to the possibility of serious injury or death if you do not follow the instructions.

Caution Symbol

CAUTION

This symbol alerts you to the possibility of damage to or destruction of equipment if you do not follow the instructions.

D Tighten all fluid connections before each use.

D Check the hoses, tubes and couplings daily. Replace worn, damaged, or loose parts immediately.

Permanently coupled hoses cannot be repaired; replace the entire hose.

D Handle and route hoses and tubes carefully. Keep the hoses and tubes away from moving parts

and hot surfaces. Do not use the hoses to pull equipment. Do not expose Graco hoses to temperatures above 180_F (82_C) or below –40_F (–40_C).

FIRE AND EXPLOSION HAZARD

Improper grounding, poor air ventilation, open flames or sparks can cause a hazardous condition and result in a fire or explosion and serious injury.

D Ground the equipment and the object being sprayed. See Ground the system on page 6. D If there is any static sparking while using the equipment, stop spraying immediately. Identify and

correct the problem.

D Provide fresh air ventilation to avoid the buildup of flammable vapors from the solvent or the fluid

being sprayed.

D Do not smoke in the spray area.

D Extinguish all open flames or pilot lights in the spray area.

D Do not turn on or off any light switch in the spray area.

D Electrically disconnect all equipment in the spray area.

D Keep the spray area free of debris, including solvent, rags and gasoline.

D Do not operate a gasoline engine in the spray area.

WARNING

EQUIPMENT MISUSE HAZARD

INSTRUCTIONS

Equipment misuse can cause the equipment to rupture, malfunction or start unexpectedly and result in serious injury.

D This equipment is for professional use only.

D Read all instruction manuals, tags, and labels before operating the equipment.

D Use the equipment only for its intended purpose. If you are uncertain about usage, call your Graco

distributor.

D Do not alter or modify this equipment. Use only genuine Graco parts and accessories.

D Check equipment daily. Repair or replace worn or damaged parts immediately.

D Do not exceed the maximum working pressure of the lowest rated system component. This pack-

age has a 100 psi (0.7 MPa, 7.0 bar) maximum working pressure at 100 psi (0.7 MPa, 7.0 bar) maximum incoming air pressure.

D Route the hoses away from the traffic areas, sharp edges, moving parts, and hot surfaces. Do not

expose Graco hoses to temperatures above 180_F (82_C) or below –40_F (–40_C).

D Do not use the hoses to pull the equipment. D Use fluids or solvents which are compatible with equipment wetted parts. See the Technical Data

section of all equipment manuals. Read the fluid and solvent manufacturer’s warnings.

D Fluid hoses must have spring guards on both ends to protect it from rupture caused by kinks or

bends at or close to the couplings.

D Comply with all applicable local, state and national fire, electrical and other safety regulations.

TOXIC FLUID HAZARD

Hazardous fluids or toxic fumes can cause serious injury or death if splashed in the eyes or on the skin, swallowed, or inhaled.

D Know the specific hazards of the fluid you are using. Read the fluid manufacturer’s warnings.

D Store hazardous fluid in an approved container. Dispose of hazardous fluid according to all local,

state and national guidelines.

D Wear the appropriate protective clothing, gloves, eyewear, and respirator.

Setup

CAUTION

This equipment is compatible with most water-based materials. See the wetted parts in the Technical Data section and your fluid and solvent manufacturer’s compatibility information.

3. Bring an air line from your compressed air supply to the pressure pot location. Be sure the air is dry and filtered. Install a bleed-type master air valve upstream from the pressure pot. When it is closed and the pressure pot air regulator (33) is opened, the bleed-type master air valve relieves all air pressure to the equipment components.

I. Prepare the operator.

All persons who operate the system should be trained in the safe, efficient operation of all system components as well as the proper handling of the chemical coating. At a minimum, all operators should thoroughly read the safety, installation and operation sections of this manual and the component manuals.

II. Prepare the site.

1. Use a minimum 5 HP (3.7 kW) air compressor for efficient operation.

2. Clear obstacles and debris that could cause an unsafe operating environment.

4. Ventilate the spray booth.

WARNING

TOXIC FLUID HAZARD

To prevent hazardous concentrations of toxic and/or flammable vapors, spray only in a properly ventilated spray booth.

Never operate the spray gun unless ventilation fans are operating.

Check and follow all of the national, state and local codes regarding air exhaust velocity requirements.

Setup

III. Unpack the system.

1. In addition to the assembled unit, these components are packed loosely or separately: hose set, gun, instruction manuals. These are the manuals you should receive:

308369 Pressure pot 308167 Air regulator 312414 HVLP spray gun (Model 237413) 312414 Air spray gun (Model 237409)

IV. Connect the hose set and gun to the

system. See Fig. 1, on page 5.

1. Connect the air hose (43) between the gun air shutoff valve (17a) and the air inlet of the spray gun. These are 1/4–18 npsm swivel fittings.

2. Connect the fluid hose (40) between the fluid shutoff valve (18) and the fluid inlet of the spray gun. These are 3/8–18 npsm swivel fittings.

3. Verify that all fittings throughout the system are tightened securely.

V. Ground the system.

WARNING

FIRE AND EXPLOSION HAZARD

To reduce the risk of static sparking, ground the pressure pot and all other equipment used or located in the spray area. Check your local electrical code for detailed grounding instructions for your area and type of equipment. Also read FIRE AND EXPLOSION HAZARD on page 2.

Ground all of this equipment:

1. Pressure pot: One end of the ground wire (13) is

already connected to the pressure pot. Connect the other end of the ground wire to a true earth ground.

2. Air compressor: Ground according to manufac-

turer’s recommendations.

3. Object being sprayed: Ground according to local

code.

4. Fluid supply container: Ground according to

local code.

5. All solvent pails used when flushing: Ground

according to local code. Use only metal pails, which are conductive. Do not place the pail on a non-conductive surface, such as paper or cardboard, which interrupts the grounding continuity.
