Startup, Shutdown, and Operation 7
7-1 Pre-Startup Checks
; Check the process hose for tight connections.
; Check hopper exhaust filter for tight connection.
; Check all companion equipment, such as the drying hopper;
verify that the loading system is ready for operation.
; Verify that all dryer electrical connections are tight.
Important!
Clean the rust-preventing oil from inside the drying hopper.
Failure to clean the hopper fouls the desiccant and voids your
warranty!
7-2 Starting Up the Dryer
1. Turn on (energize) the disconnect switch in your power drop,
then turn on the one on the dryer.
2. Turn the system
ON/OFF switch to ON to energize the display
panel.
3. Close the slidegate at the bottom of the drying hopper.
4. Fill the drying hopper with material.
5. Turn the dryer ON switch to START to start the dryer.
Heaters turn on and solenoid opens.
6. Set the process set point on the temperature controller.
7. After the proper pre-drying time for the initial hopper fill has
elapsed, fully open the drying hopper slide gate.
Note: To allow proper residence time during
continuous processing, maintain the material
level in the hopper at the midpoint of the air
trap assembly.
