local code. Use only conductive metal pails placed on a grounded surface. Do not place the pail on a nonconductive surface, such as paper or cardboard, which interrupts the grounding continuity.

• To maintain grounding continuity when flushing or relieving pressure, always hold a metal part of the gun firmly to the side of a grounded metal pail, then trigger the gun.

The equipment must be grounded to reduce the risk of static sparking. Static sparking can cause fumes to ignite or explode. Grounding provides an escape wire for the electric current.

Ground the suppressor and the rest of your system.

Ground the suppressor and all other spray equipment used or located in the spray area. The following are minimum requirements for grounding a basic spray system. Your system may include other equipment or objects which must also be grounded. Always check your local electrical code for detailed grounding instructions. Be sure your system is connected to a true earth ground.

Installation

Proper hose grounding continuity is essential to maintaining a grounded spray system. Check the electrical resistance of your air and fluid hoses at least once a week. If your hose does not have a tag on it which specifies the maximum electrical resistance, contact the hose supplier or manufacturer for the maximum resistance limits. Use a resistance meter in the appropriate range for your hose to check the resistance. If the resistance exceeds the recommended limits, replace the hose immediately.

Before flushing, be sure the entire system and flushing pails are properly grounded. See

Grounding, page 6 .

Installation

The active surge suppressor must be mounted vertically. For more information, see

Dimensions and Mounting Hole Layout, page 20

.

Three mounting kits are available:

Direct Mount Kit, 18A983, page 17

Floor/Wall Mount Surge Suppressor, 18A984, page 18

Floor Stand Adapter Kit, 18A985, page 19

1.

Assemble the breather valve (33b) to the mounting bracket (33a) with the jam nut (33c).

Torque to 8–10 ft-lb (11–14 N•m). Thread the air fitting (33d) into the breather valve (33b).

Note

Before assembling the breather valve system, verify clearances by setting up the breather valves vertically as a test.

Mounting brackets have several possible breather valve mounting configurations.

The breather valve must be mounted in a vertical position to function properly. The breather valve mounting bracket allows the repositioning of the valve for the required vertical mounting.

The breather valve system indicates a breach in the diaphragm. If a breach occurs, the working fluid passes through the diaphragm to the back side of the diaphragm. Fluid then flows into the clear tubing and into the breather valve. The breather valve stops the fluid from exiting the suppressor.

2.

Attach the assembly to the air cover (13) using a screw (18).

Note

Breather valve assemblies must be mounted and installed with the breather valve in the vertical direction for proper operation. See the illustrations in

Figure 2

for some possible mounting configurations.

3.

Connect the tubing (33e) to the fittings (33d) to complete the breather valve assembly.

Figure 2 Possible Breather Valve Mounting Positions

3A6103C 9

Installation

For optimal performance of the surge suppressor, note the following:

• Size of the inlet and outlet ports:

Each port is 1.5 inches in diameter.

• Size of the air line:

Do not use an air line smaller than 1/4 inch NPT.

• Amount of air pressure:

– The air pressure must be at least 1/3 of the fluid pressure.

– The air pressure must not exceed 100 psi

(.7 MPa, 7 bar).

For example:

– If the fluid pressure is 180 psi

(1.2 MPa, 12 bar), use an air pressure from 60–100 psi

(.4–.7 MPa, 4–7 bar).

– If the fluid pressure is 220 psi

(1.5 MPa, 15 bar), use an air pressure from 73–100 psi

(.5–.7 MPa, 5–7 bar).

Either port may be used as the fluid inlet. The direction of fluid flow does not affect the performance.

See

Dimensions and Mounting Hole Layout, page 20

.

Proper line sizing is an important part of the system.

Contact your Graco distributor if you need assistance.

To obtain proper flow through the system, use the proper size plumbing.

Use a minimum 25 mm (1 in.) diameter flexible hose between the pump and suppressor and a hard or flexible pipe after the suppressor.

A fluid drain valve is required in your system to help reduce the risk of serious injury, including splashing fluid in the eyes or on the skin, or contamination from hazardous fluids when relieving pressure.

Opening the fluid drain valve helps relieve pressure in the surge suppressor, pumps, hose, and gun after shutting off the system. Triggering the gun to relieve pressure may not be sufficient.

1.

Install a fluid drain valve (D) near the surge suppressor outlet.

2.

Install a fluid shutoff valve (C) before and after the surge suppressor to isolate it when servicing the suppressor.

Note

When using Direct Mount Kit

(18A983), install the fluid shutoff valve (C) after the surge suppressor.

( Direct Mount Kit, 18A983, page 17

.)

Operation

Follow the Pressure Relief Procedure whenever you see this symbol.

7.

Before relieving the air pressure in the surge suppressor, ensure that you have relieved the fluid pressure.

Open the surge suppressor air relief valve (39), as shown in the following figure.

This equipment stays pressurized until pressure is manually relieved. To help prevent serious injury from pressurized fluid, such as splashing clean, check, or service the equipment.

1.

Shut off the power to the pump.

• In a hydraulic system, close the hydraulic shutoff valves.

• In an air-powered system, close the pump air regulator and close the bleed-type master air valve (required in your system).

2.

Close the fluid shutoff valves from the supply tanks.

3.

Hold a metal part of the gun (if used) to a grounded metal pail. Trigger the gun to relieve the pressure.

4.

Open the fluid drain valve (required in your system), having a container ready to catch the drainage. Keep hands away from the end of the drain valve when opening it.

5.

Leave the drain valve open until you are ready to return to operation.

6.

Close the bleed type air valve that is connected to the inlet of the surge suppressor.

Figure 4 Surge Suppressor Relief Valve

1.

Open the air valve to the suppressor. The surge suppressor automatically adjusts the air charge pressure for optimal performance.

To work effectively, the air pressure must be at least 1/3 of the fluid pressure.
