
Pump or drain remaining mixed fluid out of the tank and dispose of it according to local environmental
approved practices.

Make sure both “Outlet” valves are open.

Fill and rinse the tank with clear water and then start the engine and pump. By pumping this water
through the system, it will remove buildup and dilute any remaining mixed fluid in the system. Open the
valve on the wash wand to flush it into the hopper.

Stop the engine and pump.

Drain the remaining water out of the tank and dispose of it according to local environmental approved
practices.

Remove centrifugal pump front drain plug. Leave the pump plug out.

Make sure both “Outlet” valves and wash wand valve are open.

Remove filter / shear and clean as described in the maintenance section of this manual. Leave filter /
shear out of housing as this will allow remaining moisture to drain.

Open the hopper valve and pour in a suitable environmentally friendly anti-freeze until it runs out of the
venturi open end (hose is disconnected).

Shut the hopper valve and pour a suitable environmentally friendly anti-freeze into the hopper until
