3-3 Drying
Hopper
Removing the Rust Inhibitor
Rust preventative has been applied to internal unfinished surfaces. Remove rust inhibitor
before using the drying hopper.
Using a non-water based degreasing agent, clean all inside surfaces of the drying hopper. Allow
components to dry thoroughly.
Inspect the inside of the drying hopper for loose connections, foreign objects, or a blocked
diffuser.
Air Trap Considerations
Sterling’s exclusive air trap assembly in the top of the drying hopper prevents ambient air from
contaminating the material being dried.
; Keep the material level at the mid point of the air trap for maximum efficiency.
; Use a hopper loader or vacuum conveying system to maintain the proper material level.
3-4 Installing the Sight Glass Loader
Levels A and C
; Sight glass loaders use flange mountings. See Figure 5 on Page 18 for sight glass flange
templates. You can mount the material receiver hopper directly to the processing machine by
cutting a hole in the machine bin lid and fastening the receiver to it. The material receiver
mounting flange mates with existing Sterling equipment and uses the same mounting holes as
previous Sterling models.
; Complete the vacuum and material tubing from the take-off tubes located on the SDAP cart.
See Section 3-6 on the following page for information on installing material/vacuum tubing.
; Connect the quick disconnect cable for the demand sensor to the SDAP cart. See Figure 9 on
Page 26 for more information.
