Running floating aerators usually keep an area of open water through frost. In long cold spells the spray can ice floats, walkways and nearby structures, so timers, a de-icing setting or a short shutdown are used, and moorings are checked for ice and storm loads.

## What should be checked before winter?

- Moorings and cables for wear and slack
- The power cable floats and strain relief
- Whether spray reaches walkways or rails
- A plan for long frosts: timer, de-icing setting or short shutdown

## Frequently asked questions

### Should floating aerators be switched off in frost?

Usually not, as running units keep open water. In long hard frosts, if spray ices floats or walkways, a timer, de-icing setting or short shutdown is used.
