INSTALLATION INSTRUCTIONS
Safety: Before working on machine stop engine, set park brake, remove key from ignition and block
wheels. Disconnect negative (-) battery terminal.
BOX MOUNT
Mount the switch box to the lower center of the dashboard. Remove the two phillips head bolts. Reinstall the #10
x 1 phillips head bolts and lockwashers to hold the switchbox onto the dashboard. Tighten all bolts.
WIRING
Use dielectric grease on all electrical connections. Connect power cable (15-509) to the switch box. Turn the
switch off. Route the power wire down through the grommet in the dashboard. Follow the wire harness down
under the floorboard, then back along the main frame and up to the fuse block in the engine compartment behind
the passenger seat. The power cable will need to be cut and shortened. Attach slide-on terminals to the wire
ends with heat shrink, then connect to fuse block. Red to positive(+), black to negative(-). Insert 10 AMP fuse
into slot which has red wire attached to it.
Route Control Harness (15-504) from switch box on dashboard same as the power wire. Only continue all the
way to the rear of the machine. Then pull the cable up over the back of the spray tank so it can be connected to
the compressor.
CONNECTING THE CAP ASSEMBLY
Connect the blue tube to the tank cap connector which is also connected to the large blue tube which hangs
below the cap. This is the soap outlet tube. Connect the clear tube to the other connector on the tank cap. This
is the air input tube. Tighten connectors hand tight, assembly tank cap onto tank.
HOSES
Being careful not to cut the tubing, cut the oversleeve back approximately 2" (5 cm) to expose blue and clear
tubing. Remove blue wing nut from top connector of foam nozzle and slide it on the blue tube with the threads
facing toward end of tube. Slide blue tube all the way over the top of the small tube on foam nozzle. Slide wing
nut back to the threads and hand tighten. Follow the same steps for the clear tube and tube nut.
Route the tubing along underside of main frame using tie downs as necessary.
Install opposite ends of air-liquid tubes to compressor, again cutting back the oversleeve approximately 2" (5 cm)
and inserting blue and clear tubes for the left boom section into the tubing connectors on the right side of com-
pressor as far as possible. Follow the same steps for the right boom tubing. Notice the right boom is inserted
into left side of compressor. To release tubing from compressor, hold black ring around tubing, and pull tube out.
