Operation
Adjustments
Set the actuating air to at least 75 psi (5.2 bar) and start
the pump. Set the pump speed and pressure to obtain the
desired flow rate. Always use the lowest pump speed nec-
essary to achieve desired results.
Pressure Relief Procedure
1. Shut off the power to the pump.
2. Close the bleed-type master air valve (required with
air-powered pumps).
3. Actuate the dispensing valve to relieve pressure.
4. Open the pump drain valve (required in your system) to
help relieve fluid pressure in the displacement pump.
Actuating the dispensing valve to relieve pressure may
not be sufficient. Have a container ready to catch the
drainage.
5. Leave the drain valve(s) open until you are ready to
dispense again.
If you suspect that the dispensing valve or hose is com-
pletely clogged, or that pressure has not been fully relieved
after following the steps above, very slowly loosen the
hose end coupling and relieve pressure gradually, then
completely loosen. Then clear the valve or hose.

FLUID INJECTION HAZARD
To reduce the risk of serious bodily injury, including
fluid injection, splashing in the eyes or on the skin, or
injury from moving parts, always follow this procedure
whenever you shut off the pump, when checking or
servicing any part of the dispensing system, when
installing, cleaning, or changing part of the valve and
whenever you stop dispensing.
