Pressure Relief Procedure

WARNING

PRESSURIZED EQUIPMENT HAZARD

The equipment stays pressurized until pressure is manually relieved. To reduce the risk of serious injury from pressurized fluid, accidental spray from the gun or splashing fluid, follow this procedure whenever you

DAre instructed to relieve pressure

DStop pumping

DCheck, clean, or service any system equipment

DInstall or clean fluid nozzles

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.

Flush the Pump Before First Use

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

Starting and Adjusting the Pump

WARNING

TOXIC FLUID HAZARD

Hazardous fluid or toxic fumes can cause serious injury or death if splashed in the eyes or on the skin, inhaled, or

swallowed. Do not lift a pump under pressure. If dropped, the fluid section may rupture. Always fol- low the Pressure Relief Procedure above before lifting the pump.

1.Be sure the pump is properly grounded. Refer to Grounding on page 5.

2.Check all fittings to be sure they are tight. Be sure to use a compatible liquid thread sealant on all male threads. Tighten the fluid inlet and outlet fittings securely.

3.Place the suction tube (if used) in the fluid to be pumped.

NOTE: If the fluid inlet pressure to the pump is more than 25% of the outlet working pressure, the ball check valves will not close fast enough, resulting in inefficient pump operation.

4.Place the end of the fluid hose (L) into an appropri- ate container.

5.Close the fluid drain valve (J). See Fig. 2.

6.With the pump air regulator (C) closed, open all bleed-type master air valves (B, E).

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

8.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 thoroughly clean the pump and hoses. Close the air regulator. Remove the suction tube from the solvent and place it in the fluid to be pumped.
