CONNECTING/ROUTING THE AIR LINES
This procedure should be done with the planter raised, half
folded for transport, and the row units and row cleaners fully
extended down.
The lines and fittings kit supplied is designed to enable the connection from the 2940 Air
Adjust compressor for both circuits (Down and Lift) to the Air Bags.
The primary concern is the security of the lines themselves. The lines should be fastened
to the planter in a manner that allows full range of motion/clearance of the row unit.
Special caution should be taken with rows at break or fold points of the planter as it folds
to and unfolds from transport mode.
Extra lengths of air line or alternative routing
may be necessary to stay clear of rotating parts and pinch points. See pages 30-44
for planter specific diagrams.
Due to the wide variety of planter/row unit configurations, you should adapt the
installation as necessary for your planter. Every planter will contain its own unique
situations in regard to routing the lines.
You should exercise your own best judgment
to fit your situation.
ALL lines will be 3/8” tubing
Black tubing – used for routing to DOWN pressure
Blue tubing – used for routing to LIFT pressure
Pressure specifications are the same for both colors of tubing
Lines should be placed as efficiently and conveniently as possible
Secure the Air Lines using the supplied zip tie-straps – do not pinch the line
closed when cinching tight
The air lines should be secured and routed back to the main bar to be Tee’d
into the main trunk lines
DO NOT pre-cut the line, measure and lay-out each length individually.
After completion of the
FIRST row and PRIOR to continuing to other rows, check for
clearance of, and lack of pinch points on all lines and fittings. This should be done by
completely raising and lowering both the row unit and row cleaner to their extremes,
make sure the air lines are not pinched or exposed to wear points throughout the
movement of the row unit.
Note: 2940 Air Adjust Residue Managers include a 2940-341 tubing cutter within the kit.
This cutter should be used for
every cut, to ensure a clean, square cut of the tubing.
