NH3500 Vapor Tube Installation
Locate the 1/2" EVA vapor hose supplied with the kit. Starting on
one half of the tool bar, connect the 1/2" hose to the outside
steel vapor tube. Route the hose up the shank and along the tool
bar frame to the inside steel vapor tube. Allow enough extra
hose to avoid kinking at hinge points. Cut the hose to length and
attach to the inside steel vapor tube. Install a 1/2" x 3/4" x 1/2"
tee fitting approximately halfway along this hose between the
outside and inside steel vapor tubes. See Illustration below.
Repeat the same procedure for the steel vapor tubes on the
other half of the tool bar. Secure all hoses with properly sized
hose clamps. Secure the hoses to the tool bar frame with cable
ties.
Locate the 3/4" EVA hose supplied with the kit. Connect to one
of the 1/2" x 3/4" x 1/2" tee fittings and route along the tool bar
frame to other 1/2" x 3/4" x 1/2" tee fitting. Cut to length and
install on the tee fitting. Allow enough extra hose to avoid
kinking at hinge points. Now install a 3/4" x 3/4" x 3/4" tee fitting
approximately halfway along this hose (center of the tool bar)
between the other two tee fittings. Using an appropriate length
3/4" hose, connect this tee fitting to the vapor tube connection
on the NH3500 plumbing panel. Secur
e all hoses with properly
sized hose clamps. Secure the hoses to the tool bar frame with
cable ties.
NH3500 Vapor Tube Installation
FOR ALL NH3 KITS
Weld the steel vapor tubes to
the back of your liquid tubes.
All electronic equipment,
including the console and
radar speed sensor, MUST BE
DISCONNECTED BEFORE WELDING
ON EQUIPMENT. The four steel vapor
tubes should be evenly spaced across
the applicator (two per side) and
installed so that only their wear
resistant surface contacts the
soil. Mount the tubes just high
enough to avoid plugging.

flowmeter, shut-off valve and remote
access speed connector into a single 10-pin connector.
Procedure:
Plug the 10-pin tower of the main harness onto the main
plumbing panel harness. Use 15' M/P extension cable
(provided) if necessary. Optional extension cables are available.
