Great Plains Mfg., Inc.
Control Box Assembly
Manual Control Systems Only
Refer to Figure 1-2:
To assemble the control box and attachments onto the
sprayer proceed with the following instructions:
1. Connect the brown wire to the positive terminal and
the blue wire to the negative terminal on the tractor
battery.
2. Route the battery cable into the cab of the tractor mak-
ing sure there is no sharp edges for the wires to short
out on.
!
CAUTION!
Position battery cables properly to avoid binding or cutting on
electrical wires. Failure to do so could cause injury by fire or
fire damage to tractor from shorting.
3. Connect the control box harness to the harness at-
tached on the sprayer.
4. Route the control box harness into the cab of the trac-
tor through the rear window, or opening provided in
the tractor and attach the harness to the control box.
5. Using pipe sealant, Place a small portion of pipe seal-
ant on the pressure gage threads and assemble the
reduction fitting (#1) onto the gage. Make sure that the
gage hole does not get clogged with pipe sealant.
6. Screw the 1/8” threaded quick coupling (#2) into the
reduction fitting (#1) on the back of the control box.
7. Place the gage protector magnet mount (#3) on the
back of the tractor so that it does not interfere with the
operation of the tractor, but is easily accessible.
8. Estimate the amount of tube needed from the mount-
ed control box in the tractor to the gage protector mag-
net mount (#3) and cut that length of the tube. Make
sure the tube is routed in a safe place where it won’t
be damaged while in operation.
9. With the control box laying face down, fill the gauge,
the reduction fitting (#1) and the quick coupling (#2)
with the 50/50 mixture, brim full.
IMPORTANT: The 50/50 mixture in the following
steps is a 50/50 mixture of antifreeze and water.
10. Insert the tube into quick coupling (#4).
11. Fill the gauge protector on the magnet mount brim full
with the 50/50 mixture.
12. Fill the clear tubing with the 50/50 mixture using a
short piece of 1/2 I.D. rubber hose and a small funnel.
13. With the tube completely full of the 50/50 mixture, as
well as the pressure gauge and gauge protector, in-
sert the tube into the coupling (#2). Make sure that
there is no air in the tubing when the tube is installed.
The tube will automatically lock in the coupling (#2) af-
ter insertion.
14. When removing the control box from the tractor cab,
disconnect the hose at the gauge protector quick dis-
connect (#5) and take the magnet mount with the con-
trol box so that the fluid-filled tube does not have to be
disconnected.
15. Save the coupling (#6) in case of tube damage to
make a splice.
16. Assemble the 3/8” hose from the valve bank to the
magnet mount (#3) and attach with the hose clamp
provided.
