You answered you own question: at freezing.

At or near 32 degrees F your pump should be turned to keep water moving. moving water doesn't freeze.

It is important that any exposed pipes, filter and pump have moving water at freezing as this water will freeze first and cause the item to crack. That's expensive as compared to the few cents it costs to operate the pump.

Water starts to freeze at 32 degrees. So it best to turn pump on at approx. 35 degrees & leave on until the tempt. rises to 35

How do you keep outside pipes from freezing?

Wrap them in insulation and keep the water flowing through them at all times. If electricity is available, they can be wrapped in electrical pipe heating tape to keep them above freezing temperature. Insulation over this tape will still help (if the manufacturer of the heating tape indicates it is OK and won't cause overheating).
