Determining Plenum Pressure
NOTE:
Ambient air temperature and altitude can both affect air flow. Adjust plenum pressure when these conditions affect performance.
Plenum pressure is correctly set when:
-
Equal amounts of product are delivered to each boot.
-
Tubes and hoses do not plug.
-
Hoses empty quickly and evenly when shut down.
-
Seed is not blowing out of seed trench.
