Operation
Pressure Relief Procedure
PRESSURIZED EQUIPMENT HAZARD
The equipment stays pressurized until pressure is manually
relieved. To reduce the risk of serious injury from pressur-
ized fluid, accidental spray from the gun or splashing fluid,
follow this procedure whenever you:
D
Are instructed to relieve pressure,
D
Stop pumping,
D
Check, clean or service any system equipment,
D
Install or clean fluid nozzles.
Warning
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 pressure,
having a container ready to catch the drainage.
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 contaminating your
fluid with oil, flush the pump with a compatible solvent before
using the equipment. Follow the steps under Starting and
Adjusting the Pump.
Starting and Adjusting the Pump
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.
Warning
1. Be sure the pump is properly grounded. Refer to
Grounding on page 4.
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 ineffi-
cient pump operation.
4. Place the end of the fluid hose (L) into an appropriate
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.
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.
