Mounting Bracket
1. Make sure all switches on the 744A Sprayer Control are turned to
the “Off” position.
2. Determine the best location for the 744A Sprayer Control in the
vehicle cab according to the following guidelines:
• pressure gauge should be readily visible
• switches should be within easy reach
• controller bracket should rest on a flat surface
• 12 volt DC power source must be accessible (maximum draw 10
amps)
3. Determine the proper routing for power cables and pressure tube:
• away from operators’ movement area
• away from moving parts
• away from sharp objects
4. Install the mounting bracket using ¼” (6.4mm) drill, machine
screws, nut, washers, and lock washers as illustrated below. Attach
the control housing assembly to the mounting bracket using the
console adjusting knobs and washers.
Figure 6: Mounting Bracket
output Control Cable
Cut a 1.0” (3.0 cm) diameter opening used to feed the output control
cable from the interior of the tractor cab to the boom control valves.
Make sure the hole has no burrs or sharp edges that could damage the
wires.
744A-3 Unit
6 wires from the output cable are used to control a three-section boom.
• Orange (Right) Yellow (Center) Green (Left) – connect to
144A Valves. When using a *344AEC Ball Valve, connect to the
white wire.
• **Black – connect to other terminal on 144A Valves. When using
the *344AEC Ball Valve, black is not connected.
• Red and Brown – connect to red and black wires on the Regulator
Valve (244, 344AE-PR, or 344AE-RL).
*When using 344AEC DirectoValve® Ball Valves, connect black wire(s)
and red wire(s) using the Valve End and Battery End Cables
(supplied only when Ball Valve Kits are purchased) to an
uninterrupted power supply such as the battery.
**The black ground wire for the control cable is not supplied with
connectors attached. The T-Tap connectors are supplied
separately and should be attached as per Figure 7.
WARNING!: Do not plug the control cable into the control box until it
has been fully connected to the control valves. Doing so may
allow the unconnected leads to short out.

Connector
Input power Cable
The Input Power Cable consists of three wires. The red wire should
be connected to a 12 Volt power supply within the cab of the vehicle
(i.e., ignition switch). If the power source is located outside of the
cab, the power cable should exit the cab through the same 1.0” (3.0
cm) diameter hole as the output control cable. The blue wire should
be connected to the headlight system of the tractor. This can be
accomplished by connecting the blue wire to the auxiliary terminal
of the headlight switch or by splicing into the wire connected to the
headlight. The black wire is the negative lead and should be connected
to a good chassis ground.
Plug the input power cable into the power cable socket on the back of
the 744A console. Turn the vehicle ignition switch to the “Run” position.
If the wiring has been connected properly, the boom section indicator
lights should illuminate when the boom section switches are toggled.
The gauge light should appear when the headlights are illuminated.
pressure Gauge
The tubing for the pressure gauge is supplied as part of the wiring
harness. To avoid chemical leakage into the vehicle cab, the tube
coupler should be installed outside of the vehicle cab. If a gauge
isolator is used with the system, it should be installed in place of the
coupler, also outside of the vehicle cab.
The pressure gauge should be checked for accuracy each season.
If the unit is equipped with a liquid-filled gauge and it does not read
accurately, the gauge may need to be vented. To vent the gauge,
remove the four screws in the back of the sprayer control housing and
lift off the back. The rear of the gauge will be exposed. To vent the
gauge, clip off the nib of the rubber plug in the back of the gauge or
puncture it with a needle. Once the gauge has been vented, do not
store the sprayer control on its back as this may cause a loss of fluid
from within the gauge. If further inaccuracy is suspected at 0 PSI and
a gauge isolator is being used, the isolator line may need to be bled
according to the instructions furnished with the gauge isolator.

pressure Gauge tube Assembly
1. Determine the location at which the coupler is to be installed. Cut
the tubing at that point.
2. Remove the tube nuts from the 3 couplers and slide the tubing
through the nuts. The threaded portion of the nut should face their
respective couplings. The tube should protrude approximately ½”
beyond the nut.
3. One brass tube insert is provided. This must be used with the
gauge coupling assembly.
4. A ¾” x ¾” nylon close nipple is provided if a male connected is
needed with the gauge tee fitting.
5. Fluid leakage around the gauge indicates a poor connection or a
defective gauge.
NOTE: All cables and tubes should be out of the way of the operator’s
feet and path so that they cannot be snagged or pulled. These
tubes should be routed around sharp metal objects, edges,
and moving parts with enough slack that they will not be pulled
apart when sharp turns are made.

routine procedures
Several routine procedures should be followed to help maintain the
744A Sprayer Control system.
1. Check all wires and connections for wear, damage, and frayed
ends to prevent shorting out of the system.
2. Make sure that the mounting bracket for the 744A Sprayer Control
is mounted securely.
3. All connections and terminals should be free of corrosion.
4. The control unit is designed so that it may be removed, cleaned,
and stored during periods of non-use to protect it from extreme
heat or cold.
5. The 744A Sprayer Control is NOT WATERPROOF. Do not immerse
the unit when cleaning.
6. Periodic flushing of the sprayer will help prevent clogging due to
residue buildup.
removal of Control Unit
1. De-pressurize the system.
2. Uncouple the nylon pressure tube from outside the vehicle cab and
allow the liquid to drain. Uncouple the tube from the bottom of the
unit.
3. Disconnect the input power cable from the back of the unit.
4. Disconnect the output control cable from the back of the unit.
5. Loosen the triangular knobs on both sides of the unit and slide the
unit off of the bracket.
