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.
Valve Settings
Dose valves and purge valves are factory set with the
hex nut 1-1/4 turns out from fully closed. This setting
limits maximum fluid flow rate into integrator and mini-
mizes valve response time. To open dose or purge
valves (for high viscosity materials), turn hex nut (E)
counterclockwise . To close dose or purge valves (for
low viscosity materials), turn
clockwise. See F IG . 24.

2. Close main air shutoff valve on air supply line and
on ProMix 2KE.
3. Non-IS Systems: Shut off ProMix 2KE power
(0 position). NOTE: The system will restart in
