  2. Connect the 90 degree elbow fitting to the cross fitting using a nipple fitting (A of Figure 5).

  3. Install the cross fitting on the spray pressure control valve port (B of Figure 5).

  4. Install the 90 degree side fitting to the right side of the cross fitting and the plug to the bottom (C of Figure 5).

  5. Install a 90 degree elbow to the left side of the cross fitting, connect the valve, and connect the spray hose (connected to the tank) with a hose clamp (D of Figure 5).

    Note: Route the bottom of the spray tank hose under the left tank bracket and to the back side of the machine.

  6. Connect a hose clamp on the hose that connects to the valve assembly and install the existing hose (removed in Step 1) onto the 90 degree side fitting (E of Figure 5).

    Tighten the clamp to secure the hose. Connect the other end of the hose onto the top port of the valve assembly.
