Operation
Operation
Start and Adjust the Pump
1. Be sure the pump is properly grounded. Refer
to Grounding, page 12 .
2. Check all fittings to be sure they are tight. Be
sure to use a compatible liquid thread sealant on
all male threads.
3. Place the suction line (L) in the fluid to be
pumped.
4. Place the end of the fluid outlet hose (P) into
an appropriate container (if flushing) or connect
to a gun or other dispensing device. See
Typical Installation , page 8.
5. Close the fluid drain valve (J).
6. With the pump air regulator (F) closed, open the
bleed-type master air valve (B).
7. If the fluid hose has a dispensing device, hold it
open while continuing with the following step.
8. Slowly open the air regulator (F) 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 line (L) from
compatible flushing fluid and place it in the fluid to
be pumped.
NOTICE
Operating the pump dry for extended periods
or operating at pressures higher than the
recommended maximum input air pressure may
reduce diaphragm life.
Pressure Relief Procedure
Follow the Pressure Relief Procedure
whenever you see this symbol.
This equipment stays pressurized until pressure
is manually relieved. To help prevent serious
injury from pressurized fluid, such as splashing
in the eyes or on skin, follow the Pressure Relief
Procedure when you stop pumping and before you
clean, check, or service the equipment.
1. Shut off the air supply to the pump.
2. Hold a metal part of the gun (if used) to a
grounded metal pail. Trigger the gun to relieve
the pressure.
3. Open all fluid drain valves in the system, having a
waste container ready to catch drainage. Leave
drain valve(s) open until you are ready to return
to operation.
Pump Shutdown
Short Term Shutdown
For a short term shutdown, relieve the pressure (see
procedure on this page).
Long-Term Shutdown
For a long term shutdown, such as several hours or
overnight:
1. Flush the pump thoroughly.
2. Leave compatible flushing fluid in the pump.
3. Relieve the pressure (see procedure on this
page).
