Shut off power to your Sundance® spa before servicing the filter.

Locate the filter housing and remove the old 6540-723 cartridge.

Rinse the housing thoroughly with a hose to clear away dirt or residue.

Insert the new Sundance® 6540-723 filter into the housing, ensuring it is seated properly.

Close the housing securely and restore power to the spa.

Run the pump to confirm proper installation and water circulation.

Rinse the filter every 2–4 weeks and replace annually, or sooner if water clarity declines.
