System Filling

• Connect supplied suction hose and dipleg to the 3 way fill valve.

• Place dipleg into chemical concentrate drum.

• Open 3 way fill valve (handle facing outwards).

• Make certain that all safety clips are in place.

• Slowly engage “Sandpiper Control” ball valve, located on the right side of the “Main Foam Control” panel.

• Once apparent that the unit is pumping, increase valve opening to half way.

System Filling Cont.

• Engage “Hydraulic Control Valve” located to the right of the “Main Foam Control” panel by pulling handle towards the rear of the unit.

• Pump in one drum of concentrate to make a full load of solution. 6.5:1

• Once drum is empty, fill the balance of the unit with water.

• Cat pump 400 PSI

• Air Pressure 105-110 PSI

Foaming Shut Down

• Once desired area is covered:

• At “Main Foam Control” panel, close the “Chemical” valve and reduce the “Compair” to half way.

• Make certain that the operator has a firm grasp on the discharge hose as pulsing may occur.

• Once discharge line has been purged, close “Compair” valve.

• If finished, disengage hydraulic system, rewind hose and follow previous shut down sequence.

Additional Notes • Diluted material can remain in the unit for up to 30 days.

• When using previously diluted material, start the unit and engage the “Hydraulic” valve to remix the solution.

• Foam may be applied either with or without the nozzle.
