Operation

Pressure Relief Procedure

WARNING

PRESSURIZED FLUID HAZARD This equipment stays pressurized until

pressure is manually relieved. To reduce the risk of serious injury from moving

parts, pressurized fluid, accidental spray from the valve, or splashing fluid, follow this procedure whenever you do any of the following:

DAre instructed to relieve pressure

DStop dispensing

DCheck, clean, or service any system equipment

DInstall or clean dispensing devices

1.Shut off the air supply to the pump.

2.Close the bleed-type master air valve (required in your system).

3.Hold a metal part of the dispensing valve firmly to a grounded metal waste container, and trigger the valve to relieve pressure.

If you suspect that the nozzle or hose is completely clogged, or that pressure has not been fully relieved after you have followed the steps above, do the follow- ing: Wrap a rag around the hose end coupling and relieve pressure gradually by very slowly partially loosening the fitting. Then loosen completely, then clear the obstruction.

WARNING

HAZARDOUS VAPORS

The air motor exhaust coming out of the muffler could contain harmful materials, such as oil, antifreeze, or some of the material being pumped.

To Start the Pump

1.Turn the air regulator to the minimum setting.

2.Direct the outlet hose into a waste container.

3.Open the bleed-type master air valve.

4.Slowly adjust the air regulator until the pump is running smoothly and all air has been pumped out of the pump and hoses. If the pump contains solvent, be sure to pump it all into the waste container.

5.Use the air regulator to control the pump speed and cycle rate. Always use the lowest pressure needed to obtain the desired results. This results in optimum system efficiency and reduces pump wear.

NOTES:

DThe pump only takes a few strokes to prime. How- ever, in a large system, it may take several minutes to completely prime the fluid lines.

DNever allow a pump to run dry of the fluid being pumped. A dry pump quickly speeds up and can damage itself. If it speeds up, shut off the air supply to the motor immediately. Refill the supply con- tainer, and prime the pump to eliminate air in the fluid line.

DTo prevent air from being sucked into the pump and fluid lines if the supply container runs dry, use a low-level cutoff valve at the pump intake. To order a 1 1/2-in. npt(f) thread connection low-level cutoff valve, Order Part No. 203688.
