Airline Routing –Compressor to Control Box
If using a Yetter Electric Compressor
Step 1: Install 2940-367 250psi rated 3/8 airline from the compressor outlet to the inlet port (water trap side labeled A) of the water separator.
Step 2: Install 2940-345 3/8" black airline from the outlet port of the water separator (labeled B) to the inlet port (labeled 1) on the control box.
Step 3: Install ¼" airline from ¼"PTC elbow (labeled C) on water separator to the ¼"PTC fitting (labeled 2) closest to the door hinge on control box.
Step 4: Route ¼" airline from ¼"PTC fitting (labeled 3) on side of control box toward the ground making sure the end of the airline is not pointed
toward anything that moisture may damage or rust.
Compressor Power Cable and Harness Installation
Step 1: Install the 2940-150 main power cable with 80A breaker and the 2940-166 VDM power cable with 40A breaker on the operating tractor's
battery. Red cable installs on the positive (+) battery terminal post and the black cable installs on the negative (-) battery terminal post.
Step 2: From the open 2 pole Anderson connector of the 2940-150, safely route & install the appropriate length of main power extension cables,
2940-151 is a 10ft main power extension & 2940-163 is a 20ft main power extension, into the Anderson connector that comes out of the bottom of
the compressor housing. If operating tractor is articulating or if compressor is further back on the planter than the hitch, more extension cables may
be needed. Cable length from the battery to the compressor should not exceed 50 feet. Longer than 50 feet distances cause the 80A
breaker to become weak and trip often. If distance is greater than 50 feet, heavier cable needs made using 00 gauge wire.
Step 3: From the open Anderson connector on the 2940-166, safely route/install the appropriate length of VDM power extension cables, 2940-167
(10ft) extension & 2940-168 (20ft) power extension, to the hitch of the tractor. At the hitch of the tractor, place the open 2 pole Anderson connector
next to the black CAN connector that routes to the cab controller, these are the disconnecting points when unhooking the planter from tractor.
Step 4: Install the 2940-164 5ft CAN AUX to Air harness or 2940-165 10ft CAN AUX to Air harness. The black CAN connector connects to the other
black CAN connector that comes from the cab controller. The small Anderson connector connects to the VDM power extension that routes to the
battery. The male black 12 pin Deutsch connector installs into the black female 12 pin Deutsch connector located on the bottom of the compressor
housing. If the compressor assembly is located further back on the planter than the hitch, CAN AUX to Air extension harnessing may need to be
purchased. 2940-170 is 10ft extension, 2940-171 is 30ft extension, & 2940-430 is a 20ft extension.
