Pressure Relief Procedure

Pressure Relief Procedure WARNING

INJECTION HAZARD

The system pressure must be manually relieved to prevent the system from starting or spraying accidentally. Fluid

under high pressure can be injected through the skin and cause serious injury. To reduce the risk of an injury from injection, splashing fluid, or moving parts, follow the Pressure Relief Procedure whenever you

DAre instructed to relieve the pressure

DStop spraying

DCheck or service any of the system equipment

DInstall or clean the spray tip

1.Lock the gun trigger safety and any other equipment safety locks.

2.Turn off the power to the pump.

3.Unlock the gun trigger safety.

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

5.Hold a metal part of the gun firmly to the side of a grounded metal pail, and trigger the gun to relieve pressure.

6.Lock the gun trigger safety.

7.Slowly open the drain valve (required in your system), and have a container ready to catch the drainage.

8.Leave the drain valve open until you are ready to spray again.

If you suspect that the spray tip or hose is completely clogged, or that pressure has not been fully relieved after following the steps above, very slowly loosen the tip guard retaining nut or hose end coupling, and relieve pressure gradually, then loosen completely, then clear the tip or hose.

Operating the Regulator

Operating the Regulator CAUTION

DTo avoid contaminants clogging or damaging the regulator, you must clean and test the new system thoroughly before you admit fluid to the regulator.

DAlways use the lowest possible air and fluid pressures for your application. High pressures can cause premature spray tip and pump wear.

NOTES:

DThe fluid pressure regulator controls pressure downstream from its outlet.

DIf using an accessory fluid pressure gauge (H), to ensure a correct gauge reading, relieve the spray gun line pressure after reducing the regulator pressure.

1.Back the regulator adjusting screw (18) out (turn counterclockwise) until there is no spring pressure. Relieve the spray gun line pressure.

2.Turn the adjusting screw clockwise to increase the fluid pressure.

3.Adjust the pump air pressure and fluid regulator for the desired spray pattern. Use the lowest possible air and fluid pressures for your application.

4.In a circulating system, also adjust the back pressure valve.

5.Record all the settings for future reference.
