of the air has been pushed out of the lines, close
the dispensing valve.
NOTE: When the pump is primed, and with sufficient air
supplied, the pump starts when the dispensing valve is
opened and shuts off when it is closed.
4. If the system is equipped with a runaway valve (D),
set it for the system configuration. See Pump
Runaway Valve manual for setting instructions.
5. Adjust the air regulator until there is sufficient flow
from the dispensing valve. Always run the pump at
the lowest speed necessary for the desired results,
making sure not to exceed the maximum working
pressure of any component in the system.
NOTE: Stop the pump if it is accelerating too quickly or
is running too fast, and check the fluid supply. If the
supply container is empty and air has been pumped
into the lines, prime the pump and lines with fluid, or
flush it and leave filled with a compatible solvent.
Ensure that all air is eliminated from the fluid lines. If the
system has a runaway valve, reset it according to the
instructions in the Pump Runaway Valve manual.
Do not allow the pump to run dry of the fluid being
pumped. A dry pump will quickly accelerate to a high
speed, possibly damaging itself, and it may become
very hot.
6. Read and follow the instructions supplied with each
of your system components.
7. If the pump will be unattended for any period of
time, if there is an air supply interruption, or to shut
off the system at the end of the work shift, relieve
pressure following the Pressure Relief Procedure,
page 8.
8. Periodically check that the pump's mounting is
secure.
