Pressure Dampener
The pressure dampener is mounted to the pressure line
at the spray pump (Fig. 4) and is used to smooth system
pressure pulsation. Adjust air pressure on the pressure
dampener to approximately 14 PSI (.97 bar). If fluid is
present when pressure in the dampener is checked, the
diaphragm in the pressure dampener is damaged and
should be replaced.
