Step 4: Screw the filter housing tightly
Tighten the blue filter housing by hand. Then, use supply filter wrench to tighten the
blue filter housing.
Step 5:
Slowly turn on the main inlet valve. Turn off the water outlet after the
domestic water equipment is able to dispense water. Be sure to check whether there
is water leakage or slow water seepage at the joints.
Caution:
Do not use a hot water faucet to perform the initial system flush.
Notice:
The water will be blackish in color for the initial flush. This is residual carbon
dust and is to be expected. Continue to run water until it runs clear and all air has
been purged. Shut the water off and let the unit sit for a while, and then flush again. It is
not unusual for the water to appear "cloudy" for a day or so following installation. This
cloudiness is actually tiny air bubbles being purged from the filters. This is normal and
will clear up in a day or two.
After prolonged periods of nonuse (such as a vacation), it is recommended that the
system be flushed thoroughly for at least 10 minutes before using the water.
