Connection: Quick-connect stems 4/6, both ends
Use: Disposable, sealed

Shut off the unit's water supply and open the faucet to relieve pressure.
Detach the used filter from its connection stems and remove it from its clip.
Connect the new filter, observing the flow direction on the housing (IN → OUT).
Slowly reopen the water supply and check the connections for leaks.
On first use, flush for at least 5 minutes until the water runs clear to remove carbon fines.

The filter is disposable and cannot be opened or washed. Replace it after 9,462 litres or every 6 months at the latest; replacing it together with the other pre-filters in the system is recommended. Do not use with microbiologically unsafe water or water of unknown quality without disinfection.
