INTRODUCTION
Congratulations! And thank you for choosing TeeJet Technologies’ advanced 844 sprayer control system. With its
proper installation and maintenance, you can enjoy many seasons of accurate and uniform spray application with
fingertip convenience and ease of operation.
Installation and Programming of your control system will be covered in easy to follow, step-by-step instructions.
NOTE: WE RECOMMENDTHAT YOU READTHESE INSTRUCTIONS COMPLETELY before attempting
installation and programming of your 844 sprayer control. The unit’s performance will depend on its proper
installation and programming, along with planned preventative maintenance of your entire sprayer.
Easily Accessible
Programming Mode
is very user-friendly. The
process is made simple
with a series of easy-
to-follow, symbol-driven
programming steps.
844E SPRAYER CONTROL
Auto/Manual Control
gives the operator a
manual application option
for fail-safe reliability.
Master Shuto
controls all boom sections
with one switch.
Color-Coded Tip Selection Bar
allows for easy user programming by
matching the color of TeeJet VisiFlo®
spray tips.
Individual Boom Controls
give independent control of up to five boom sections,
allowing better management of varying field features
like waterways and terraces.
Boost Mode
will temporarily increase or
decrease application rates for
special situations, such as in
patches of heavy weeds.
A Large, Backlit Display
continuously displays all vital spraying
functions. With a quick glance, the
display reveals the application rate
(automatically switches between
target and actual), pressure, speed,
and area covered.
Aluminum Console Housing
with sealed computer switch panel
resists electronic interference and
damage through rough handling for
years of reliable service.

MOUNTING SPRAYER COMPONENTS
Pressure Regulator in Bypass Mode
All pressure regulating valves for the 844 will be wired for use in a
by-pass system. While plumbed in a by-pass mode, with the Auto/
Man key in the “MAN” mode, the valve should close when the
key is pressed and open when the key is pressed.
The pressure regulating valve can also be mounted in a throttling
situation as an alternative location. Refer to page 5, and Figures
1-3 and 1-4.
NOTE: The diagrams in Figures 1-1 and 1-2 are shown as general
guidelines to follow when plumbing the 844 components.
The type of pump used and location of other components
can vary from sprayer to sprayer. It is important to ensure
that if a pressure transducer is used, it is located as close
to the spray tips as possible. Normally, this is at the boom
control valves. However, if one particular boom section is
always used, the pressure transducer can be mounted on
that particular boom section. If a flow meter is used, make
sure that all of the flow going through the flow meter is
directed to the spray tips. Make sure that proper distance
is allowed on the inlet and outlet side of the flow meter
(refer to figures 1-2 and 1-3).

Pressure Regulator in Throttling Mode
The pressure regulating valve, as shown in the figures below, can be located in the supply line before the boom
control valves. If you choose this location, the 844 will need to be properly programmed to reverse the polarity of
the valve. This step can be found in the System Setup instructions on page 23. When in throttling mode, the valve
should open when the key is pressed, and close when the key is pressed. Be sure to check this before
plumbing the valve into the system.
