Practical tips for installation and care
- Power off the filtration system before replacing the cartridge. Remove the old cartridge, rinse the housing, and check O-rings for wear.
- Install the new Darlly cartridge with the end caps aligned to fit the wiring and plumbing orientation, ensuring the 2" slip fittings engage cleanly.
- After installation, run the system for a few minutes to prime the cartridge and check for leaks. If you notice bypass or reduced flow, reseat the cartridge and inspect end caps.
- Periodically rinse the cartridge with clean water (no detergents) to remove loose surface debris. Replace when you notice significant flow drop or visible fouling that rinsing cannot restore.
