Replacing the DuoClear Cartridge
A DuoClear cartridge lasts six months. Replace the cartridge as soon as the DuoClear Nature2
Cartridge life indicator light turns red and flashes.
WARNING: As the DuoClear system requires sufficient residual silver in the system to sanitize
effectively with the low chlorine levels, the pool will not be sanitized sufficiently if the DuoClear
system is operated without replacing the DuoClear Nature2 cartridge when indicated.
Always turn pump off prior to removing any part of the DuoClear system. The pump/filter system
is operated under pressure and pressure must be released before you begin. Open the air relief
valve on the pool filter to release the pressure in the system.
To replace the cartridge:
1.
Turn off the pool pump and release pressure.
2.
If appropriate, close valves between the filter and pool to prevent
draining the pool.
3.
Unscrew cartridge retaining ring and remove cartridge.
4.
Install the new cartridge.
5.
Lightly coat o-ring with silicone lubricant and ensure it is seated.
6.
Tighten the cartridge retaining ring.
7.
Open any valves that were closed to isolate the DuoClear vessel.
8.
Restart your pool’s pump and filtration system. Check for leaks.
9.
Follow the start up procedures under Operation.
