Manifold Gas Pressure Adjustment
When the manifold gas pressure is adjusted, the front cover will be off.
Adjust the manifold gas pressure to the value of "Cover Off" in the table
(because it is not possible to adjust the manifold gas pressure with the
front cover on).
Use the following procedure to adjust the manifold gas pressure only
if it can be done with a high flow rate through the unit.
Press and hold the "Minimum Manifold Pressure Set Button".
Use the "Manifold Gas Pressure Increase and Decrease Buttons"
to adjust to the correct pressure.
With a manometer or pressure gauge connected to the manifold
pressure tap, press and hold the "Maximum Manifold Pressure
Set Button". Use the "Manifold Gas Pressure Increase and
Decrease Buttons" to adjust to the correct pressure.
Repeat steps (1) and (2) until both are at the correct pressure. (3)
