NH3500 Kit Installation
Remove any existing metering valves. If the old metering valve
has a built-in manifold, it is recommended to install a separate
new manifold for the NH3500 kit.Another option, although not
recommended, is to use the existing manifold, making certain
the old metering valve is in the maximum open position to
allow for minimal restriction of flow through the plumbing.
There also should not be any positive shut-off valves installed
in the plumbing between the NH3500 kit shut-off valve and
the knives.
Locate a convenient area on the applicator to install the
NH3500 plumbing panel. When selecting an installation
location, keep in mind that the hose from the break-away
coupler must reach the strainer inlet with enough length to
allow for proper operation of the break-away coupler
disconnect mechanism and prevent kinking of the hose at
hinge points. Also, the strainer’s clean-out plug should be
accessible for regular cleaning. Make certain that the area
selected allows for enough length of the manifold hose,
between the manifold and the servo valve outlet, to prevent
kinking at hinge points.
INSTALLATION NOTE: It is recommended to use an NH3
compatible thread sealing compound such as “Slic-tite
paste with Teflon”, or a similar compound, on all pipe
thread fittings. Slic-tite is manufactured by LA-CO
Industries, Inc./Markal Company.
Remove the NH3500 plumbing panel from the shipping board.
Install the plumbing panel on the tool bar frame using the
bottom brackets, carriage bolts and flange lock nuts. Trim any
excess length off of the bolts if required. Attach the hose from
the br
eak-a
w
a
y c
oupler t
o the str
ainer inlet.
Check hose length
for proper operation of the break-away coupler disconnect
mechanism. Next, connect the manifold hose to the servo
valve outlet. Check for proper hose length to avoid kinking at
hinge points.
