Installation

General Information

NOTE: Reference numbers and letters in parentheses

in the text refer to the callouts in the figures and the parts drawing.

NOTE: 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.

Prepare the Operator

All persons who operate the equipment must be trained in the safe, efficient 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.

The following manuals are included with this equipment:

D 3A1450, 3:1 President Pump D 306982, President Air Motor D 307273, 307282, or 308918, Fluid Filter D 307068, Fluid Ball Valves D 308401, Back Pressure Regulator

Prepare the Site

Ensure that the wall is strong enough to support the weight of the pump and accessories, fluid, hoses, and stress caused during pump operation.

Ensure that you have an adequate compressed air supply. Refer to the performance chart on page 21 to find the air consumption.

Refer to Fig. 2 on page 9. Bring a compressed air supply line (A) from the air compressor to the pump location. 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.

Install a bleed-type shutoff valve (B) in the air line to isolate the air line components for servicing. Install a moisture trap and drain valve (C) to help remove moisture and contaminants from the compressed air supply.

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

Refer to Fig. 2 on page 9.

WARNING

A red-handled bleed-type master air valve (11h) and a fluid drain valve (D) are supplied. These components help reduce the risk of serious injury, including splashing of fluid in the eyes or on the skin, and injury from moving parts if you are adjusting or repairing the pump.

The bleed-type master air valve relieves air trapped between this valve and the pump after the air is shut off. Trapped air can cause the pump to cycle unexpectedly. Locate the valve close to the pump.

The fluid drain valve assists in relieving fluid pressure in the displacement pump, hose, and gun. Triggering the gun to relieve pressure may not be sufficient.

D The red-handled bleed-type master air valve

(11h) is required in your system to relieve air

trapped between it and the air motor when the valve is closed (see the WARNING above). Be sure the bleed valve is easily accessible from the pump, and is located downstream from the pump air filter/regulator (11a).

D The pump air filter/regulator (11a) controls pump

speed and outlet pressure by adjusting the air pressure to the pump. It includes an air filter with a 40 micron polypropylene element, to remove harmful dirt and moisture from the compressed air supply. Locate close to the pump, but upstream from the bleed-type master air valve (11h).

D The air line lubricator (11b) provides automatic

lubrication of the air motor.

D The air relief valve (11j) opens automatically to

prevent overpressurization of the pump.

D Fluid is supplied to the pump through the suction

hose (16) and tube (50). See Fig. 2.

D The fluid filter (5) includes a 60 mesh (250 mi-

cron) stainless steel element to filter particles from the fluid as it leaves the pump.

D The fluid drain valve (D), is mounted in the bot-

tom of the fluid filter bowl, and is required in your system to relieve fluid pressure in the hose and gun (see the WARNING at left).

D The back pressure regulator (12) controls back

pressure to the gun and maintains proper circulation pressure.

Conversion Modules

Supply Module 239857

Part No. 239857 Supply Module is available to convert a pump module to a circulation package. The supply module includes an elevator, stainless steel drum cover, back-geared agitator with suction tube, and connecting hardware. See manual 308769.

Heater Modules 239850 (120V), 239851 (240V), and 239852 (220/240V)

Three Heater Modules are available to convert a pump module to a heated system. Each module includes a heater configured to the desired voltage, and mounting hardware. See manual 308771.

308768 7

Installation

Installing the Pump Module

The pump module consists of the pump mounted on the pump bracket, the air controls, back pressure regulator, hoses, and plumbing.

NOTE: Refer to Fig. 2 on page 9, and to the Dimension drawing on page 22 and the Mounting Hole Layout on page 23.

1. Ensure that the wall is strong enough to support the weight of the pump and accessories, fluid, hoses, and stress caused during pump operation.

2. Position the bracket mounting plate (37) on the wall so the edge with the hook is facing up. Mount the plate so the top edge is 4 to 5 ft (1.2 to 1.5 m) above the floor. Check that the plate is level. Mark two holes on the wall, using the plate as a template. Drill two holes and attach the plate with 1/2 in. bolts and washers.

3. Using two people, hang the pump module on the bracket mounting plate (37). Have one person hold the module in place while the other checks that the pump bracket (22) is level. Mark four holes on the wall, using the pump bracket as a template. Remove the pump module.

4. Drill four holes in the wall.

WARNING

Using the Quick Connectors

To open a quick connector (11c), loosen the captive screw (S) and open the connector. Slide the desired component into the connector, close, and tighten the screw. See Fig. 1.

11c

Connect the Fluid Lines

Connect a 1 to 3 ft (0.3–0.9 m) hose (E) to the ball valve (15) at the outlet of the fluid filter (5), to isolate the pump module from the main fluid line. Connect the other end of the hose to the main fluid line (F).

The pump bracket (22) must be bolted to the wall with four bolts. Do not simply hang the pump bracket on the bracket mounting plate (37).

5. Lift the pump module back into position, hang it on the bracket mounting plate (37), and bolt the pump bracket (22) to the wall. Use 1/2 in. bolts and washers to mount the pump module to the wall. Use bolts that are long enough to keep the pump bracket (22) from vibrating during operation.

Connect the fluid return line (G) to the ball valve (14) at the inlet of the back pressure regulator (12). The return hose (21) connects the back pressure regulator to the 3-way recirculation valve (19).

Connect the Air Line

Connect the main air supply line (A) to the tee (11k) of the air filter/regulator/lubricator assembly (11).
