Startup, Shutdown, and Operation 7
7-1 Pre-Startup Checks
; Check the process and return hoses for tight connections.
; 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!

continuous processing, maintain the material
level in the hopper at the midpoint of the air
trap assembly.
