Daily checks
Daily: check the motor — rotation sound, bearing condition; check the reducer for oil leakage; check the impeller for deformation or damage; check the circuit for phase loss and the junction box for corrosion.
Post-season maintenance
Post-season: disassemble and maintain after a season of use, apply sufficient grease to all parts, and store in a ventilated, dry place; reassemble when needed.
Frequently asked questions
Q: How often does an aerator need checking? A: Two rhythms. In season it is checked every day; at the end of the season it is disassembled, greased and put into dry storage.
Q: What does the daily round cover? A: The rotation sound and bearing condition of the motor, the reducer for oil leakage, the impeller for deformation or damage, the circuit for phase loss, and the junction box for corrosion.
Q: Why is the post-season service separate from the daily check? A: They catch different things. The daily round watches for what changes between shifts — noise, leaks, damage — while the post-season strip-down is the only point where parts are taken apart, greased and stored properly.
Q: When should the aerator be disassembled? A: After a season of use. That is the point the maintenance routine is built around, rather than something to do only in response to a fault.
Q: How should an aerator be kept between seasons? A: Disassembled and maintained, with sufficient grease on all parts, in a ventilated and dry place — then reassembled when it is needed again.
