Please read all instructions and precautions before installing and using your Crystal Quest® Countertop Water Filter.
Numbered diagrams correspond with numbered steps.
Use this system on a potable (safe-to-drink) COLD water supply only. Do not install on hot water line.
Do not use non-Crystal Quest® replacement cartridges.
Do not use non-Crystal Quest® parts or modify/tamper with unit.
WARNING: Do not use with water that is microbiologically unsafe or of unknown quality without adequate disinfection before
or after the system. Systems certified for cyst reduction may be used on disinfected water that may contain filterable cysts.
CAUTION: Filter must be protected against freezing which can cause cracking of the filter and water leakage.
• Filter cartridge life varies depending on filter type, usage, and water conditions. The replacement filter cartridge used
with this system has a limited service life. Changes in taste, odor, or reduced flow of the water being filtered can indicate
that the cartridge should be replaced.
• The contaminants or other substances removed or reduced by these systems are not necessarily in your water. Ask your
local water municipality for a copy of their water analysis or have your private well tested by a reputable water testing lab.
• After prolonged periods of non-use (such as during a vacation), it is recommended that the system be flushed thoroughly.
Let water run for 5-6 minutes before using. Repeat if necessary.
NOTE: Adapters are included which will fit most faucets. To create
a tight seal, you may need to use the gasket from your faucet’s
aerator in addition to the washers included with the adapters. If
the adapters do not fit, consult your local plumbing or hardware
supplier for assistance in obtaining the correctly threaded adapter.
A drinking water cartridge may contain carbon fines (very fine
black powder). After installation, flush the cartridge 3-4 times
per flush for 5-10 minutes to remove the fines before using the
water. Repeat as required.
It is recommended that you run the tap at least 20 seconds prior
to each use for drinking or cooking purposes.
During initial use, your water may appear cloudy. This cloudiness
is caused by air that has been trapped in the cartridge. If the
water sits for 5 minutes in a glass, you will notice the cloudiness
disappear from the bottom up. This phenomenon is not harmful
and will clear up in time as the remaining air is flushed from the
