Dimensions

End-capped design; C: end cap inner diameter.
* Typical for 20 °C water; lower flow increases contact time. ** 2 mg/l free chlorine, > 75 % reduction at the recommended flow.
NSF-marked models: 6-03-GAC10, 6-03-GAC10-C.

Operating Conditions

Operating pressure: 1.4 - 8.6 bar (20 - 125 psi)
Operating temperature: 4 - 45 °C (39 - 113 °F)
Pre-filtration: Sediment filter (5 µm) recommended
Replacement interval: 6 months max.

Materials and Construction

Filter media: Granular activated carbon (GAC)
Carbon source: Coal or coconut shell
Shell and end caps: Plastic (typically polystyrene)
End configuration: Gasketed end caps, carbon fines pad
Gaskets: Elastomer
Use: Disposable, not washable

Shut off the water supply and relieve the pressure in the housing.
Open the housing, remove the used cartridge and clean the housing and O-ring.
Unwrap the new cartridge, seat it in the centre of the housing, check the O-ring and close the housing.
Slowly reopen the water supply and check for leaks.
On first use, flush for at least 5 minutes until the water runs clear to remove carbon fines.

GAC cartridges are disposable and cannot be washed and reused. Replace the cartridge every 6 months at the latest, or when chlorine taste or odour returns. Black carbon fines in the first flow are normal. Do not use with microbiologically unsafe water or water of unknown quality without disinfection.
