Installation, Maintenance, and Care
- Power off the equipment and relieve system pressure before replacing the cartridge.
- Remove the old cartridge, inspect O-rings and seals, rinse the housing, and pre-wet the new cartridge with clean water.
- Install the FC-1977 cartridge with the open top and bottom facing the correct flow direction, then reseal and restart the system.
- For optimal performance, rinse the cartridge between uses and perform a full cleaning cycle if flow slows or water clarity drops. Consider a manufacturer-recommended filter cleaning solution if needed, and replace cartridges when there is noticeable degradation in filtration performance.
- Regularly inspect for wear and tears, and replace as part of routine spa/pool maintenance—roughly aligned with usage and water conditions.
