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
every 6 months. However, it can be replaced earlier if there is a
drop in pressure at the faucet.
To reduce Chlorine Taste and Odor,
use Replacement Filter: WHCF-GAC
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 incoming water
supply. Place a bucket under filter to catch the small amount
of water that will run out after housing removal.
1. Shut off water.
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. Turn on water. If any leaks appear, tighten housing as needed.
7. Flush system for five (5) minutes.
Troubleshooting Guide
Water Leaks at Threaded Fittings:
Tighten slightly more until leak stops.
Water leaks at Push-in Connections
Push tubing in as far as it will go. If leaking continues, shut off
water at the original valve and remove water line by pushing in on
the connector collar while pulling the tubing away. (See Push-in
Fittings Section) Inspect tubing for cracks and scratches. If tubing
is cracked or scratched, simply cut that portion away and reinsert
tubing into fitting.
Make sure tubing is cut straight. If not, recut.
