Operation

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 with lightweight oil, which is left in the fluid passages to protect parts. To avoid contam- inating your fluid with oil, flush the pump with a com- patible solvent before using the equipment. Follow the steps under Starting and Adjusting the Pump.

Starting and Adjusting the Pump

WARNING

TOXIC FLUID HAZARD

To reduce the risk of serious injury, splashing in the eyes or on the skin, and toxic fluid spills, never move or lift a

pump under pressure. If dropped, the fluid section may rupture. Always follow 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.

10 308441

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.Close the pump air regulator (C). 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.

Operation of Remote Piloted Pumps

1.Follow preceding steps 1 through 7 of Starting and Adjusting Pump.

2.Open air regulator (C).

WARNING

The pump may cycle once before the external sig- nal is applied. Injury is possible. If pump cycles, wait until end before proceeding.

3.Pump will operate when air pressure is alternately applied and relieved to push type connectors (14).

NOTE: Leaving air pressure applied to the air motor for extended periods when the pump is not running may shorten the diaphragm life. Using a 3–way solenoid valve to automatically relieve the pressure on the air motor when the metering cycle is complete prevents this from occurring.

Pump Shutdown

WARNING

To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the Pressure Relief Procedure at left.

At the end of the work shift, relieve the pressure.
