Operation
Starting and Adjusting the Pump
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure
at left.
1.
Close the pump regulator and the bleed-type
master air valve.
2.
Point the dispense valve into a grounded metal
waste container, making firm metal-to-metal con-
tact between the valve and the container. Open
the dispense valve.
3.
Open the bleed-type master air valve. Open the air
regulator slowly, until the pump just starts running.
4.
Run the pump until it is primed and all air has been
pushed out of the fluid line, then close the dis-
pense valve. The pump will stall against the pres-
sure. With the pump and lines primed, and with
adequate air pressure and volume supplied, the
pump will start and stop as the dispensing valve is
opened and closed.
NOTE:
If the pump is difficult to prime,
relieve the
pressure
and remove the hose. Prime the pump
alone, then reconnect the hose and continue to
prime your system.
5.
Use the air regulator to control the pump speed
and the fluid pressure. Always use the lowest air
pressure necessary to get the desired results.
Higher pressures cause premature nozzle and
pump wear. Never overpressurize any component
in the system. See the
Maximum Working Pres-
sure
warning on page 8.
6.
Never allow the pump to run dry of the fluid being
pumped.
CAUTION
A dry pump quickly accelerates to a high speed,
possibly damaging itself. If your pump accelerates
quickly or is running too fast, stop it immediately and
check the fluid supply. If the supply container is
empty and air has been pumped into the lines, refill
the container and prime the pump and the lines with
fluid, or flush and leave it filled with a compatible
solvent. Be sure to eliminate all air from the fluid
system.
7.
Read and follow the instructions supplied with
each component in your system.
Shutting Down the Pump
Before you shut down the pump, follow all the steps of
the
Pressure Relief Procedure
at left.
