PLEASE READ
For optimum performance, we have included two
different media valve diaphragms.
Installed in the media valve is our high-pressure
diaphragm part #411157.
If the media valve does not shut off immediately upon
releasing the foot pedal, you may need to change the
diaphragm.
For lower pressure uses we recommend installing the
low-pressure diaphragm part #411164
Whenever the media does not shutoff, you should first
inspect the diaphragm for wear.
