The digital vacuum gauge console controls EdgeVac vacuum fan. Use “FAN 1” setting when planter is equipped with
one vacuum fan.
NOTE: Toggle switch must be OFF when planter is not in use or tractor battery will drain.
The digital vacuum gauge is factory calibrated. However, vacuum varies throughout the manifold system and it may be
necessary to adjust the digital readout so it agrees with actual vacuum at the meter. With the seed discs loaded with
seed, compare digital vacuum gauge readout to reading taken from analog gauge or a hand held gauge at several
meters along length of planter.
Elbows at seed meter covers allow testing of meter vacuum levels without removing vacuum hoses. If there is more
than 1" or 2" (H
O) difference, adjust gauge by inserting a small flat bladed screwdriver into opening on back of digital
gauge housing and turning potentiometer until digital gauge displays meter vacuum reading.
Compare readings at 10" and 20" of vacuum.
The analog vacuum gauge connects directly to the manifold or is teed into
the digital sending unit on newer models.
Only gauge adjustment is to “zero” needle with no vacuum present. If
there is a significant difference between this gauge and a reading taken at
meters, a different manifold location should be found to connect hose to
gauge and digital sending unit.
