Flow Diagram
Enviro-Flush System
The Enviro-Flush system is a closed system which pulls ushing solvent from the Flush Tank, pumps it through the
circulating system and spray bar and returns the solvent to the Flush Tank.
Complete the appropriate suck back procedure(s) found in your Black-Topper® operation manual.
Flushing Solvent must be in the Enviro-Flush tank for this procedure.
On the cab control panel, turn on the POWER switch and complete the instructions beginning on the next page.
Normally the suckback procedure will remove sufcient material from the circulating system to negate the need for
performing the Enviro-Flush procedure.
