Auto-Assisted Cleanout
New to the Maximizer 2B is the Auto-Assisted Cleanout
Function. This is a timed sequence which introduces
solvent into the spraybar, asphalt pump, and associated
plumbing; circulates it for a period of time to clean
asphalt residue from the spraybar and components
and then deposits the used solvent into the Enviroush
Tank. Auto-Assisted Cleanout should only be used after
the REVERSE SUCTION function has been completed.
There are two forms of Auto-Assisted Cleanout.
1. Diesel Tank Cleanout: This uses the driver side
Diesel Tank for the solvent.
2. Enviroush Tank Cleanout: This uses the passenger
side Enviroush Tank which holds the used solvent
or alternative solvent to diesel fuel.
Both modes of Auto-Assisted Cleanout pump used
solvent into the Enviroush Tank at the conclusion of the
cleanout cycle.
Diesel Tank Auto-Assisted Cleanout
Description:
• Operator runs the distributor in REVERSE SUCTION
MODE to remove as much asphalt from the spraybar
and pump system as possible.
• Operator selects CLEANOUT MODE from the
Mode Selection Screen of the In-Cab Control. The
distributor must be set to REAR control.
• Operator selects CL.OUT DIESEL on the Passenger
Rear Fender Control to initiate the cycle.
• Asphalt Pump runs forward while the Solvent Circulate
Valve is closed and the Solvent Valve is opened. This
introduces solvent into the spraybar and pump system
from the driver side Diesel Tank. In time the Solvent
Circulate Valve opens and the solvent circulates
through the asphalt pump and spraybar.
• Solvent Valve closes as the asphalt pump continues
to run forward causing the solvent to circulate through
the spraybar and pumping system. This is a timed
sequence.
• Asphalt Pump stops and reverses direction as the
Solvent Circulate Valve closes and the Enviroush
Tank Valve opens. Dissolved asphalt is pumped from
the spraybar into the Enviroush Tank.
• Asphalt Pump stops and the Enviroush Tank Valve
closes.
• Auto-Assisted Cleanout cycle is complete.
Enviro Tank Auto-Assisted Cleanout
Description:
• Operator runs the distributor in REVERSE SUCTION
MODE to remove as much asphalt from the spraybar
and pump system as possible.
• Operator selects CLEANOUT MODE from the
Mode Selection Screen of the In-Cab Control. The
distributor must be set to REAR control.
• Operator selects CL.OUT ENVIRO on the Passenger
Rear Fender Control to initiate the cycle.
• Asphalt Pump runs forward while the Solvent Circulate
Valve is closed and the Enviroush Tank Valve is
opened. This introduces solvent into the spraybar
and pump system from the passenger side Enviroush
Tank. In time the Solvent Circulate Valve opens while
solvent circulates through the asphalt pump and
spraybar.
• Enviroush Tank Valve closes and the asphalt
pump continues to run forward causing the solvent
to continue to circulate through the spraybar and
pumping system. This is a timed sequence.
• Asphalt Pump stops and reverses direction as the
Solvent Circulate Valve closes and the Enviroush
Tank Valve opens. Dissolved asphalt is pumped from
the spraybar into the Enviroush Tank.
• Asphalt Pump stops and the Enviroush Tank Valve
closes.
• Auto-Assisted Cleanout cycle is complete.
