General Information

Reference numbers and letters in parentheses in the text refer to the callouts in the figures and the parts drawing.

Always use Genuine Graco Parts and Accessories, available from your Graco distributor. If you supply your own accessories, be sure they are adequately sized and pressure-rated for your system.

FIG. 1 is only a guide for selecting and installing system components and accessories. Contact your Graco distributor for assistance in designing a system to suit your particular needs.

Prepare the Operator

All persons who operate the equipment must be trained in the operation of all system components as well as the proper handling of all fluids. All operators must thoroughly read all instruction manuals, tags, and labels before operating the equipment.

Prepare the Site

Ensure that you have an adequate compressed air supply.

Bring a compressed air supply line from the air compressor to the pump location. Refer to the performance charts in your pump assembly manual to find the air consumption of your pump. Be sure all air hoses are properly sized and pressure-rated for your system. Use only electrically conductive hoses. The air hose should have a 3/8 npt(m) thread. A quick disconnect coupling is recommended.

Wall Mount Packages

1. Be sure the wall can support the weight of the pump, bracket, hoses and accessories, as well as the stress caused during operation.

2. Position the wall bracket about 4–5 ft (1.2–1.5 m) above the floor. For ease of operation and service, make sure the pump air inlet, fluid inlet, and fluid outlet ports are easily accessible.

3. Using the wall bracket as a template, drill 0.4 in. (10 mm) mounting holes in the wall. Wall mounting dimensions are shown on page 33.

4. Attach the bracket to the wall. Use 3/8 in. (9 mm) screws that are long enough to keep the pump from vibrating during operation.

NOTE: Be sure the bracket is level.

Ventilate the Spray Booth

Provide fresh air ventilation to avoid the buildup of flammable or toxic vapors. Do not operate the gun unless ventilation fans are operating.

Electrically interlock the gun air supply with the ventilators to prevent gun operation without ventilating fans operating. Check and follow all National, State, and Local codes regarding air exhaust velocity requirements.

Keep the site clear of any obstacles or debris that could interfere with the operator's movement.

Have a grounded, metal pail available for use when flushing the system.

Installation

Supplied Components

See FIG. 1. Components vary by package ordered. See tables on pages 6 to 7. Your package may include:

• The red-handled bleed-type master air valve (U) is required in your system to relieve air trapped between it and the air motor and gun when the valve

is closed.

Trapped air can cause the pump to cycle unexpectedly, which could result in serious injury from splashing or moving parts.

• The pump air regulator (X) controls pump speed and outlet pressure by adjusting the air pressure to the pump.

• The air relief valve (not shown) opens automatically to prevent overpressurization of the pump.

Do not block access to the valve.

• The 3-way valve (M) allows choice to circulate fluid back to the pump or return it to the supply container.

• A fluid drain valve (G) relieves fluid pressure in the hose and gun.

•The fluid heater (D) heats the fluid as it passes through, to maintain the correct spraying viscosity.

Read and understand all instructions in the supplied heater manual 309524 before operating the heater.

Heat causes fluid to expand. If the heated fluid is trapped with nowhere to expand, it can cause component rupture. Be sure to keep the heated fluid circulating (turn the 3-way valve to CIRC). Do not install a fluid shutoff device between the heater and the gun.

• The gun air regulator (T) adjusts the air pressure to the air-assisted spray gun (H).

• The air-assisted or airless spray gun (H) dispenses the fluid. The gun houses the spray tip (not shown), which is available in a wide range of sizes for different spray patterns and rates of flow. Refer to gun manual for tip installation.

• The hose bundle (L) supplies fluid (and air for AA guns) to the gun, and allows recirculation of fluid when the gun is not triggered.

• The gun swivel (J) allows for freer gun movement.

• The suction hose (N) with strainer (P) allows the pump to draw fluid from a 5 gallon (19 liter) pail.

• A fluid filter (F) with a 60 mesh (250 micron) stainless steel element filters particles from fluid as it leaves the pump.

• DataTrak (V) provides pump diagnostics and material usage information. See page 19.

• The back pressure regulator (E) controls pressure back to the gun and maintains proper circulation pressure.

Installation

Grounding

The equipment must be grounded. Grounding reduces the risk of static and electric shock by providing an escape wire for the electrical current due to static build up or in the event of a short circuit.

1. Pump: See F is attached and tightened securely to the air motor. Connect the other end of the ground wire (R) to a true earth ground.

FIG. 2. Ground screw and wire

2. Pump fluid hoses: use only electrically conductive fluid hoses Check electrical resistance of hoses. If total resistance to ground exceeds 25 megohms, replace hose immediately.

3. Viscon HP Heater: refer to the heater manual, supplied.

4. Air compressor: follow manufacturer's recommendations.
