Use: Disposable, sealed

Shut off the unit's water supply and open the faucet to relieve pressure.
Remove the used filter from the HF connection head; use the 3-95-HFSA removal tool if needed.
Remove the protective caps from the new filter and push it fully home, observing the IN / OUT direction.
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; mark the change month on the label.

The filter is disposable and cannot be opened or washed. Replace it after 9,462 litres or 1 year, whichever comes first; replace earlier if chlorine taste or odour returns. Do not use with microbiologically unsafe water or water of unknown quality without disinfection.
