  1. Place the multi-port valve in a neutral position for the winter. This is either between any two grooves, or the “winterize” position if one is indicated on your multi-port valve.

  2. If you have a Nature2 Express, remove the cartridge.

  3. If you have an automatic chlorinator, drain it, remove the tablets (be sure to follow the manufacturer’s instructions for safe chemical handling), thoroughly rinse with fresh water and replace the lid, but leave it loose enough to allow any gases to escape.

  4. If you have a salt water pool, disconnect the cell part of the salt system, unplug it from the power center and bring it indoors for the winter. Make sure to follow the manufacturer’s directions on cleaning it for the winter.

  5. If you have an automatic cleaner that uses hoses to attach to your skimmer (such as a Baracuda), take all of the hoses apart and store them straight. Do not coil hoses or they will not work next spring.
