NOTICE:
Every effort has been made to ensure the
accuracy of the information contained in
this manual. All parts supplied are selected
specially to fit the sprayer to facilitate a
complete installation. However, NORAC
cannot guarantee all parts fit as intended
due to the variations of the sprayer by the
manufacturer. Please read this manual
in its entirety before attempting
installation.
ATTENTION:
When installing the UC4+ Spray Height
Control system please be aware that at a
point in the installation your sprayer booms
will be inoperative until the installation is
complete. Any installation procedure
requiring boom movement will need
to be done first. Once the hydraulics
have been disconnected you must complete
the electrical installation before the booms
become operative.
