Operation
Pressure Relief Procedure
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 con-
taminate the fluid you are pumping, flush the pump thor-
oughly with a compatible solvent. Follow the steps under
Starting and Adjusting the Pump.
Starting and Adjusting the
Pump
1. Be sure the pump is properly grounded. Refer to
Grounding on page 8.
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. Re-torque all screws and fasteners before startup.
Re-torque the fluid cover screws first, followed by
the manifold screws.
4. Place the suction tube (E) in the fluid to be pumped.
5. Place the end of the fluid hose (J), see F
IG
. 3, into
an appropriate container.
6. Close the fluid drain valve (G). Open the fluid shutoff
valve (H).
7. With the pump air regulator (C) closed, open the
bleed-type master air valve (B).
8. If the fluid hose has a dispensing device, hold it
open while continuing with the following step.
9. 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 thor-
oughly clean the pump and hoses. Close the air regula-
tor. Remove the suction tube (E) from solvent and place
it in the fluid to be pumped.
Pump Shutdown
Short Term Shutdown
For a short term shutdown, relieve the pressure (see at
left).
Long Term Shutdown
For a long term shutdown, such as several hours or
overnight:
1. Flush the pump thoroughly.
2. Leave compatible solvent in the pump.
3. Relieve the pressure (see at left).
WARNING
Read the warnings on page 3, and follow the Pressure
Relief Procedure below whenever you:
• are instructed to relieve pressure
• stop spraying
• check or service any of the equipment
• install or clean the fluid nozzle.
Operating the pump beyond the maximum air
input pressure will decrease diaphragm life.
Do not operate the pump dry for long periods of
time to avoid reducing diaphragm life.
