Operation
Pressure Relief Procedure
PRESSURIZED EQUIPMENT HAZARD
The equipment stays pressurized until pressure is manually
relieved. To reduce the risk of serious injury from pres-
surized 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 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 in water. If water could contaminate
the fluid you are pumping, flush it thoroughly with a compat-
ible solvent.
Follow the steps under Starting and Adjusting
the Pump.
Starting and Adjusting the Pump
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 follow the Pressure Relief
Procedure above before lifting the pump.
Warning 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 inefficient 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. 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.
Pump Shutdown
Warning
To reduce the risk of serious injury whenever you are
instructed to relieve pressure, always follow the Pres-
sure Relief Procedure at left.
At the end of the work shift, relieve the pressure.
