2. To read hydraulic motor chamber pressure:
Rotate knob until the arrow points to the port where tubing from the
hydraulic motor chamber is connected. The hydraulic motor
chamber is located at the end of the filter opposite the cover.
Note: During normal (filtering only) operation, the hydraulic motor
chamber pressure should be equal to the inlet pressure. During
the rinse cycle, the hydraulic motor chamber pressure should drop
to 25-40% of the inlet pressure.
3. To read outlet pressure:
Rotate knob until the arrow points to the port connected to the
outlet leg of the filter.
Note: To determine differential pressure across the filter, subtract
the outlet pressure from the inlet pressure.
