OPERATOR'S MANUAL

STORAGE

To prevent unnecessary down-time when preparing the airlock for use after storage, it is
important to carefully follow the storage preparation procedures.
To prepare the airlock for storage, proceed as follows:
1. Clear the area of bystanders, especially small children.
2. Place all controls in neutral, stop and lock-out the power source, and wait for all moving
parts to stop.
3. Thoroughly inspect the airlock for any damaged or worn components; repair or replace
any components as required before storage with reference to Section 7: Maintenance
and Adjustments to prevent down-time at the beginning of the next season.
4. Wash the airlock thoroughly using a water hose or pressure washer to remove all dirt,
dust, debris, and residue. The internal surfaces of the airlock can be cleaned through
flushing. To flush the internal surfaces, proceed as follows:
a. Position the outlet/discharge line to allow free discharge of water.
b. Run the airlock at a high idle speed with the airlock rotating.
c. Allow water to enter the airlock inlet for several minutes, allowing time for the
water to wash out the casing interior, the rotating airlock blades, inlet and outlet
surfaces, and the connected discharge components.
d. Stop the water flow into the inlet and continue to run the airlock for several
minutes to allow all interior surfaces to completely dry.
e. When conveying materials with oily characteristics or high moisture content,
including milled feeds, the airlock may need to be flushed on a more regular
basis to remove residue build-up. Oily residues may require flushing and soaking
with a suitable solvent to dissolve build-up. Any non-food-grade solvents must be
cleaned from the machine using hot water and/or detergent flushing. Ensure that
any solvent used is acceptable for the intended market of the conveyed products.
5. With reference to Section 7: Maintenance and Adjustments, lubricate all grease
points. Ensure all grease cavities have been filled with grease to remove any water
residue from washing.
6. Coat the internal surfaces of the airlock with a rust inhibitor/anti-corrosive oil.
7. Touch up all paint nicks and scratches to prevent rusting.
8. Install a debris cover on the inlet and/or outlet if they are exposed to prevent
accumulation of dirt, dust and debris and further limit rusting of the internal surfaces.
9. Move the airlock to its storage position. The storage position should be dry, level and
free of debris, and does not have frequent human activity in the vicinity.
After storage, refer to Section 7: Maintenance and Adjustments to ensure all necessary
maintenance tasks are completed. Once the required maintenance tasks have been completed,
proceed to the standard pre-operation checks as outlined in Section 6: Operation and resume
normal operation.
