Airline Routing - Yetter AIR ADJUST 2940 Operator's Manual

Airline Routing-Planter Frame
Below is a suggested method for safely & securely routing the airlines on the planter frame whether installing trunk airlines (airlines
routing to the row cleaner air bags) or supply airlines (airlines that route from the compressor housing to the dump valve's inlet port).
Safely route the airlines on the frame that the row units are mounted to or follow the path to which the hydraulic hoses on the planter
are routed. After airline & dump valve harnessing is complete, use provided zip ties to keep parts away from pinch & wear points.
Airline Routing-Row Unit
Below is a suggested method for safely and securely routing the airlines from the air bag to the tees on the planter frame. These
are generalizations and YOU SHOULD USE YOUR OWN BEST JUDGEMENT in routing airlines. DO NOT pass the airlines
between the rear of the parallel arm & the row unit. DO NOT pass airlines between the frame & the head plate used to mount the
row unit to the planter frame. These can act as both a pinch points & wear points. If necessary, use provided zip ties to keep
airlines away from pinch & wear points & sharp or rotating objects that may damage the airline.
Specific airline routing will be dependent upon: Row unit make & model (AGCO, CNH, JD, Kinze, etc), row unit spacing (15", 20",
22", 30", 36", etc), parallel arm length, & other variables. RM units will have 1 up pressure & 1 down pressure air bag & RM/Coulter
Combo models will have 2 air bags on the bottom of the bracket for up pressure & a single air bag on top is for down pressure. The
2 up pressure air bags will have airline already tee'd together so the lift pressure trunk airlines will need plumbed to that tee.

Airline Routing

The following pages are dump valve & airline diagrams of different planter models. Dump valve cable length may vary from
the directions given. For example, a 24 row planter on 30 inch centers will have different length dump valve cables than a 24
row planter on 20 inch centers. The wiring & tubing kit will have everything needed to complete the installation.
Direction of flow is: Supply Tank  Water Separator Assembly  Control Box  Dump Valves  Air Bags All airlines will be 3/8".
Blue airline should be used on all lift pressure (smaller) air bags & black airline should be used on all down pressure (larger) air bags.
Use the airline colors to differentiate the lift pressure (Blue Airline) and down pressure (Black Airline) on the planter for
troubleshooting, leak detection, & dump valve circuit indication. Route the airlines as efficiently and conveniently as possible.
If there is no diagram for your situation, contact a Yetter service representative (800-447-5777) & a drawing will be made.
