Filter Replacement:
The contaminants or other substances removed or reduced by
this water filter are not necessarily in all users’ water.
Filter life varies depending on local water conditions and the vol-
ume of water used. We recommend that you change your filter
as prescribed by the filter documentation, however, it can be
replaced earlier if there is a drop in water pressure.
You can use a variety of Whirlpool filters with this housing:
WHCF-GD05, WHCF-WHPL, WHCF-WHSW, or WHCF-WHWC.
Do not use with water that is microbiologically unsafe or of unknown quali-
ty without adequate disinfection before or after the system.
Systems certified for Cyst reduction may be used on disinfected water
that may contain filterable cysts. EPA Establishment #070595-CT-001
Filter Cartridge Replacement Instructions:
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 shutoff valve at filter head.
2. Relieve pressure in housing by pushing red vent button.
3. Unscrew housing and remove old cartridge. Wash housing
thoroughly with mild soap and water.
4. Insert new cartridge and re-install housing. Be sure cartridge is
seated in the housing before tightening onto head.
5. Use filter wrench to fully seat the cartridge. Tighten to make a
water tight seal.
6. Open shutoff valve at filter head. If any leaks appear, tighten
housing as needed.
7. Flush system for five (5) minutes.
