FILTER CARTRIDGE REPLACEMENT INSTRUCTIONS
To reduce the risk associated with property damage due to water leakage:
• The disposable fi lter cartridge must be replaced every six months or at the specifi ed service cycle.
The contaminants or other substances reduced by this water filter are not necessarily in all user's water.
Filter life depends on local water conditions and the volume of water used. We recommend you change your filer as pre-
scribed by the filter documentation. However, it can be replaced earlier if there is a drop in water pressure.
You can use a variety of filters with this housing: AP810, AP811 and AP814 for sediment and rust; AP815 and AP817 for
Sediment, Chlorine Taste & Odor.
NOTE: Before changing cartridge, turn off water supply. Place a bucket under filter to catch the small amount of water
that will run out after housing removal.
1. Close shut-off valve after filter head.
2. Relieve pressure in filter housing by pushing red vent button.
3. Unscrew housing to the left and remove old cartridge. Wash housing thoroughly with mild soap and water.
4. Lubricate o-ring with a silicone based lubricant.
5. Insert new cartridge and re-install housing. Be sure cartridge and o-ring are seated in the housing before tightening
onto head.
6. Open main shut-off valve and check for leaks. If any leaks appear, tighten housing as needed. Open shut-off valve
after filter head.
7. Flush system for five (5) minutes.
Water Leaks at Fittings:
Tighten slightly until leak stops.
If Leaks Persist:
Shut off water at the main water supply shut-off valve, remove threaded fittings, reapply PTFE tape in a clockwise direc-
tion (to the right) and screw back onto head assembly.
