Document the salt-system close
- Identify the salt generator model and read its winterizing section.
- Record power isolation and the cell's before condition.
- Document the model-approved drain, removal, or circulation plan.
- Photograph the cell, spacer or capped plumbing, and storage location.
Pentair's IntelliChlor manual describes cold-water production limits and warns of freeze damage without preventative measures. Its closing path includes draining the system and removing, cleaning, and storing the cell, or continuously circulating during freezing conditions. That is an example for IntelliChlor, not an instruction for an unknown system. Other cells and controllers may use different spacers, unions, cables, and storage steps.
Do not improvise
Disconnecting a cell can expose electrical connections or leave an open hydraulic path. Use the exact manual and a qualified technician. Do not treat a low-temperature shutdown indicator as proof that the plumbing is protected from ice.
Proof to capture
- Controller and cell model plates, display, and visible cell condition.
- Power state and removed-cell or drained-in-place decision.
- Spacer, unions, caps, or other installed winter component.
- Where the cell and small parts will be stored for opening.
Questions
Will a salt cell produce chlorine in cold water?
Production can stop in cold water; Pentair's IntelliChlor manual states its cell will not produce chlorine below its specified low-temperature cutoff. Check the installed model and test water rather than assuming output.
Should every salt cell be removed for winter?
No universal rule covers every system. The installed model's manual and the chosen full-close or active-circulation plan decide whether to remove, drain, store, or protect the cell.
