5-7 Color Change
The color change procedure is meant for use with the basic OS/OA Blender. This
procedure assumes that the color component of the blend is in an additive
ingredient hopper (#2, #4, #5, or #6).
Note: The blender must be stopped to make color changes. The processing
machine can operate on virgin material only during this procedure with an
optional quick color change bypass tube that can be installed to bypass the
blender. Contact the factory for details.
1. Disable and clean any color loading equipment. Please refer to the
loading equipment manual for any clean up recommendations.
2. Using the blender key, put the blender in stop mode. After the
cycle has completed, switch the main power switch and unplug
the blender power supply.
3. Open the upper mixer access door. This shuts off air to the blender circuit
by deactivating the master air valve. Then unplug the quick disconnect
from the air supply hose to the blender to further ensure that no air
pressure is supplied to the blender.
WARNING!
• Always unplug the main power cord.
• Always disconnect the air supply to the blender.
...prior to performing any operations inside any access areas of
the blender where there are moving parts.
