NOTE: Do not change system type, number of guns,

hose length, hose diameter, dosing type, or number of

colors when material is loaded in the system. Change

these inputs only if system hardware is changed.

If you change one of these inputs, the system locks so

that you cannot spray or mix. The lock icons display.

Power down and power back up again to clear the lock

and put the new settings into effect. The lock ensures

that the selection was intended and prevents operation

with incorrect settings.

mizes valve response time. To open dose or purge

valves (for high viscosity materials), turn hex nut (E)

counterclockwise

low viscosity materials), turn

clockwise.
