Features and installation
- Serviceable lamp and quartz sleeve with twist-cap access.
- Remote power supply and inline plumbing layout.
- Choose connection size before ordering; both options at each wattage use the same corresponding lamp.
- Requires a suitable water supply from a separately supplied pump or circulation system.
UV treats water that passes through the chamber. It does not replace filtration, routine maintenance, quarantine, or disease treatment. Follow the manufacturer's installation and electrical safety instructions and never operate an exposed UV lamp.
