Suction valve allows the operator to select which tank the solution pump draws from. With valve handle (A) in position shown, the solution pump will only draw from the solution tank. Rotating valve handle to the opposite direction will close off the solution tank and allow the pump to draw only from the rinse tank.

Pressure valve allows the operator to direct the flow of solution once it exits the pressure side of the solution pump. With valve handle (A) in position shown, solution is directed to the spray boom for normal spraying operation.

With valve handle rotated to the left, solution is directed to the rinse nozzles inside the solution tank.

With valve handle rotated to the right, solution is directed to solution tank when using the sprayers solution pump to load.

Quik-Fill valve completes the connection between the nurse tank and the sprayer.

Once the nurse tank hose has been connected to the machine, rotate valve handle (A) until parallel with plumbing to open the connection between the nurse tank and the sprayer.

After filling procedure is completed, rotate handle back to the closed position as shown before disconnecting nurse tank hose from the sprayer.

Bypass valve allows the operator to select loading method.

To spray or load the sprayers solution tank using a nurse pump, valve handle (A) must be in a horizontal (normal position) as shown.

To load the sprayers solution tank using the sprayers solution pump, place valve handle (A) in the vertical (bypass) position. After loading the sprayer using this method, the handle must be rotated back to horizontal (normal position) to resume spraying.

Decal (B) explains bypass valve functions.

Eductor flow rate valve allows the operator to direct solution to a venturi at the top of the solution tank. This venturi creates the vacuum needed to draw solution from the eductor into the solution tank.

Rotate valve handle (A) to a horizontal position to create suction at the eductor.

Rotate valve handle back to a vertical position to stop suction as shown.

Decal (B) explains eductor flow rate valve functions.

Eductor hopper valve allows chemical to be drawn from bottom of eductor hopper to top of solution tank.

It is only operational when the eductor flow rate valve is open.

Eductor rinse valve allows operator to direct solution to rinse eductor hopper and rinse chemical containers.

Rotate valve handle (A) to rinse.

It is only operational when the eductor flow rate valve is open.

Agitation flow rate valve allows the operator to regulate the amount of agitation inside the solution tank.

Turn on agitation solenoid valve (A) and then rotate valve handle (B) to create desired agitation in the tank.

For no agitation, rotate handle perpendicular to solution hose as shown, or turn off agitation switch in cab.

NOTE: To minimize foaming run at lower agitation rate.

Turn off agitation when tank volume drops below 378.5 L (100 gal) to prevent foaming and air in system.

Strainer shut-off valve (A) allows the operator to close the pressure line when cleaning the pressure line strainers. Closing the pressure line limits the amount of solution that will drain and reduces the amount of air introduced to the system.

To open, rotate handle parallel to solution hose as shown.

To close, rotate handle perpendicular to solution hose.

NOTE: Close strainer shut-off valve when filling sprayer using nurse system pump to avoid air being forced into boom.

Flowmeter shut-off valve (A) allows the operator to close the pressure line when cleaning the flowmeter(s). Closing the pressure line limits the amount of solution that drains and limits the amount of air introduced to the system.

To open, rotate handle parallel to solution hose as shown.

To close, rotate handle perpendicular to solution hose.

CAUTION: Do not close the flowmeter shut-off valve with the solution pump running. This can trap pressure in the boom that can be hazardous when removing flowmeters for cleaning.

The solution tank valve is used to close off the solution tank from the rest of the wet system in case repairs are required in the system.

Rotate valve handle (A) perpendicular to solution hose as shown to close valve.

Rotate valve handle parallel to solution hose to open.
