9. After the proper pre-drying time for the initial hopper fill has elapsed, fully open the
drying hopper slide gate.
10. Turn the machine loader ON/OFF switch to ON, and set the convey timer for the proper
conveying time. A ten- (10-) second convey time is recommend to start.
11. Adjust the inner tube on the take-off compartment if material does not flow easily to the
sight glass loader on the molding press.
12. If you are running out of material at the sight glass before the machine loader starts the
convey cycle again, lower the dump delay time by adjusting the yellow jumpers inside
the control panel.
Note: To allow proper residence time during continuous processing, maintain the material level
in the hopper at the midpoint of the air trap assembly.
5-3 Shutdown
1. Turn off the conveying system supplying the drying hopper.
2. When processing is complete, close the hopper slide gate and shut down any in-line
companion equipment, such as the aftercooler.
3. Turn the dryer ON/OFF selector switch to the SEQUENCE SHUTDOWN position. The
sequence shutdown operation turns off process heaters and keeps the process blower on
for twenty minutes to cool down the process. The regeneration cycle of the off-line bed
completes the cycle before the dryer shuts down completely.
4. To override the sequence shutdown turn the system ON/OFF switch to OFF .
5. To completely shut off the unit after sequence shutdown has completed, turn the system
ON/OFF switch to OFF .
6. If needed, empty the drying hopper.
7. For maintenance or a long term shutdown, open (de-energize) the electrical disconnects
at the dryer and at the power drop.
