Installation

1.Install the air line accessories as shown in FIG. 3. Mount these accessories on the wall or on a bracket. Be sure the air line supplying the accesso- ries is grounded.

a.Install an air regulator (C) and gauge to control the fluid pressure. The fluid outlet pressure will be three times the setting of the air regulator.

b.A bleed-type master air valve (B) is required in your system to relieve air trapped between it and the pump when the valve is closed. Trapped air can cause the pump to cycle unexpectedly which could result in serious injury including splashing in the eyes or on the skin, or injury from moving parts. Be sure the bleed valve is easily accessible from the pump, and is located downstream from the air regulator.

c.The air line filter (D) removes harmful dirt and moisture from the compressed air supply.

d.A second bleed-type air valve (T) isolates the air line accessories for servicing. Locate upstream from all other air line accessories.

2.Install a grounded, flexible air hose (A) between the accessories and the pump air inlet. See Technical Data on page 25 to determine the air inlet size of your pump. Use a minimum 13 mm (1/2 in.) ID air hose.

3.Screw an air line quick disconnect coupler (N) onto the end of the air hose (A), and screw the mating fit- ting into the pump air inlet snugly. Do not connect the coupler to the fitting until you are ready to oper- ate the pump.

Fluid Suction Line

???Use conductive hoses (E). See FIG. 3.

???See Technical Data on page 25 to determine the fluid inlet size of your pump.

???For maximum suction lift (wet and dry) information, see Technical Data on page 25.

1.Use conductive fluid hoses (J). See FIG. 3. See Technical Data on page 25 to determine the fluid outlet size of your pump.

2.Install a fluid drain valve (G) near the fluid outlet. The fluid drain valve is required to relieve pressure in the hose and gun. The drain valve reduces the risk of serious injury, including splashing in the eyes or on the skin, or injury from toxic fluids.

3.Install a shutoff valve (H) in the fluid outlet line.

Pressure Relief Procedure

Read the warnings on page 3, and follow the Pres- sure Relief procedure below whenever you:

???are instructed to relieve pressure

???stop spraying

???check or service any of the equipment

???install or clean the fluid nozzle.

1.Shut off the air to the pump.

2.Open the dispensing valve, if used.

3.Open the fluid drain valve to relieve all fluid pres- sure, having a container ready to catch the drain- age.

7.With the pump air regulator (C) closed, open the bleed-type master air valve (B).

8.If the fluid hose has a dispensing device, hold it open while continuing with the following step.

9.Slowly open the air regulator (C) until the pump starts to cycle. Allow the pump to cycle slowly until all air is pushed out of the lines and the pump is primed.

If you are flushing, run the pump long enough to thor- oughly clean the pump and hoses. Close the air regula- tor. Remove the suction tube (E) from solvent and place it in the fluid to be pumped.

Operating the pump beyond the maximum air input pressure will decrease diaphragm life.

Do not operate the pump dry for long periods of time to avoid reducing diaphragm life.

Flush the Pump Before First Use

The pump was tested in oil. If the oil could contaminate the fluid you are pumping, flush the pump thoroughly with a compatible solvent. Follow the steps under Start- ing and Adjusting the Pump.

Pump Shutdown

Short Term Shutdown

For a short term shutdown, relieve the pressure (see at left).

Starting and Adjusting the Pump

1.Be sure the pump is properly grounded. Refer to

Grounding on page 9.

2.Check all fittings to be sure they are tight. Be sure to use a compatible liquid thread sealant on all male threads.

3.Re-torque all screws and fasteners before startup. Re-torque the fluid cover screws first, followed by the manifold screws.

4.Place the suction tube (E) in the fluid to be pumped.

5.Place the end of the fluid hose (J), see FIG. 3, into an appropriate container.

6.Close the fluid drain valve (G). Open the fluid shutoff valve (H).

Long Term Shutdown

For a long term shutdown, such as several hours or overnight:

1.Flush the pump thoroughly.

2.Leave compatible solvent in the pump.

3.Relieve the pressure (see at left).

Maintenance

Maintenance

Lubrication

CAUTION

Lubrication of the pump is not required. Oil is exhausted through the muffler, which could contami- nate the fluid supply or other equipment. Excessive lubrication can also cause the pump to malfunction.

Flushing and Storage

Flush the pump with a compatible solvent often enough to prevent the fluid you are pumping from drying in the pump and damaging it. Follow the Pressure Relief Pro- cedure on page 10 before storing it for any length of time.

Tighten Threaded Connections

1.Before each use, check all hoses for wear or dam- age, and replace as necessary.

2.Check to be sure all threaded connections are tight and leak-free.

3.Check and re-torque all screws and fasteners at least every two months. Re-torque the fluid cover screws first, followed by the manifold screws.

NOTE: Before using pump, loosen fluid cover screws (31) 1-2 turns and then re-torque to 20 N???m (15 ft-lb).

Preventive Maintenance
