2. Cut the hose at the mark with a utility knife so that you have the following lengths of hose section:

   • 20.3 cm (8 inches)

   • 53.3 cm (21 inches)

1. Install the bulkhead fitting into the hole at the bottom of the rinse tank as follows:

   1. Install a clear gasket onto the bulkhead fitting as shown in Figure 5.

   2. Flange-head bolt (3/8 x 1 inch) and flange locknut (3/8 inch)

2. Move the valve mount rearward (Figure 11).

   Note: This is a adjustment in the valve mount location allows space for installing the rinse tank.

3. Torque the 4 flange-head bolts (3/8 x 1 inch) and 4 flange locknuts (3/8 inch) to 37 to 45 N∙m (27 to 33 ft-lb).

4. Remove the retainer fork that secures the 90° barbed fitting of the supply hose to the housing of the suction screen (Figure 12).

5. Repeat steps 2 through 4 for the other hold down at the other recess in the rinse tank (Figure 14).

6. Carefully tighten the bolts and flange nuts by hand.

   Important: The rinse tank must be seated and secure, but the hold down should not deform or warp the tank.

7. Replace the supply hose at the rear of the tank and secure it with the retaining fork removed previously.

Note: Once the rinse tank has been initially filled, check the hold downs and the rinse tank for play (the weight of the water in the tank can further seat the tank against the frame). If needed, tighten the bolt(s) and flange locknut(s) until the hold downs are snug against the rinse tank—do not deform the tank; refer to Inspecting the Rinse Tank Hold Downs.

1. Align the 90° barbed fitting of the supply hose with the housing for the suction screen (Figure 15).

   Figure 17

   1. Drill marks

3. Move to the drill mark behind the tank lid.

   Note: Place a container inside the tank below the areas where you are drilling to catch falling debris.

   Important: Debris left inside a tank could clog and damage the spray system during operation.

4. Use a hole saw to make a hole—4.5 cm (1-3/4 inches) at the drill mark (Figure 18).

   Note: If a lower amperage fuse already exists in the slot, replace it with the fuse (40 A).

4. Locate relay and power relay in line with the other relays of the same style, and mount them to the panel (Figure 34, Figure 35, or Figure 36) with the 2 flange-head bolts (#10-24 x 1/2 inch) and 2 locknut (#10-24).

5. Locate the 4-socket connector and the 5-socket connector on the main harness and connect them to the relay (5-pin) and power relay (4-pin) as shown in Figure 34, Figure 35, or Figure 36.

2. Working from underneath the dash panel, remove the cable tie that secures the 8-socket connector labeled RINSE TANK from the main harness.

3. Route the 8-socket connector toward the open hole in the dash (Figure 37 or Figure 38).

4. Connect the 3-position switch into the 8-socket connector through the dash panel (Figure 37 or Figure 38).

5. Insert the 3-position switch into the opening in the dash panel until the latch of the switch snap securely into the dash (Figure 37 and Figure 38).

The Rinse Kit is controlled by a 3-position switch (Figure 40 or Figure 41).

• The rinse-tank pump is on with timed rinse when you press the 3-position switch up position and it locks—the delay timer runs the pump.

  Note: For 2015 and before machines, the switch illuminates.

• The rinse-tank pump is off when you press the 3-position switch to the middle position.

• The rinse-tank pump is on momentarily: when you press and hold the 3-position switch in the down position to run the pump.

  Note: For 2015 and before machines, the switch illuminates.

Park the machine on a level surface, engage the parking brake, shut off the sprayer pump, shut off the engine, and remove the key.

Remove the rinse tank cap, fill the tank with approximately 113 L (30 gallons) with clean water, and install the cap.

Important: The 113 L (30 gallon) rinse tank is only intended to be filled with clean water. The introduction of any other substance to the rinse tank can cause a safety hazard and/or damage the machine.

Once the rinse-tank pump has moved 38 L (10 US gallons) of water into the sprayer tank, the user can use the agitation switch at their disposal to put the clean water into the agitation loop. Once finished, the rinsate can be sprayed out of the boom nozzles or manually drained from tank. This allows the machine to move during the rinse processes.

1. Turn on the rinse-tank pump by performing 1 of the following:

   • Press up 3-position switch for a timed rinse.

   • Press and hold down the 3-position switch for a desired duration.

2. Once the rinse-tank pump has moved 38 L (10 US gallons) of water into the sprayer tank, use the agitation switch to circulate the clean water through the agitation loop.

3. Pump the rinsate out of the sprayer tank as required by federal, state, and local regulations by performing 1 of the following:

   • Spray the rinsate through the booms until the sprayer tank is empty.

   • Draining the sprayer tank contents into a suitable container and disposing of the diluted solution as required by federal, state, or local regulations.

The rinse cycle can be repeated again as necessary for 2 more timed rinse cycles.
