1. Turn off water supply to filter.
2. Turn off tank Valve and open the faucet to relieve the
pressure in the system.
3. Unscrew housing using filter wrench.
NOTE: When opening filter housing to change cartridge, it is
common for O-ring/Gasket to lift out of housing and stick to
cap.
4. Remove used cartridge and discard. Rinse out housing
and fill about 1/3 full with water. Add about 2 to 3
tablespoons of bleach and scrub thoroughly with brush or
sponge. Rinse thoroughly.
5. Remove O-ring/Gasket from sump and wipe groove and
O-ring/Gasket clean. Lubricate O-ring/Gasket with a
coating of clean silicone grease. Place O-ring/Gasket back
in place and press O-ring down into the groove.
NOTE: This step is important to ensure proper filter seal. Make
sure the O-ring is seated level in the groove (or gasket is on
rim of sump).
CAUTION: If O-ring/Gasket appears damaged or crimped it
should be replaced at this time. See your local dealer for
replacements parts.
6. Insert a new cartridge into the sump making sure that it
slips down over the sump standpipe.
7. Screw the sump onto the cap and hand tighten. DO NOT
OVER-TIGHTEN. Make sure cartridge slips over the cap
standpipe.
8. Repeat these steps for all 3 pre-filters.
9. Remove the fittings from the post carbon filter and discard
old filter. Wrap the fittings with Teflon tape (about 3
wraps). Install the fittings in the new filter and attach the
tubing.
10. Turn on the water supply slowly to allow housing to fill with
water.
11. Check for leaks before leaving installation.
WARNING: Do not use with water that is microbiologically
unsafe or of unknown quality without adequate disinfection
before or after the unit.
NOTE: Activated carbon cartridges and carbon block
cartridges may contain a small amount of carbon fines (very
fine black powder) and a new cartridge, after installation,
should be flushed with sufficient water to remove the fines
before using the water. Each time you use water from your
filtered water tap for drinking or cooking purpose, it is
recommended that you run (flush) the tap at least 10 seconds
prior to using water. This is particularly important if the water
tap is not used daily.
NOTE: Replacement cartridges have a limited service life.
Changes in taste, color and flow of the water being filtered are
signals that replacement of the cartridge is or soon may be
necessary.
CAUTION: Filter housing must be protected against freezing
and extreme temperatures. Filter housings should not be in
direct contact with sunlight for a prolonged period of time since
UV rays can make housings brittle. Pressure should always be
measured before installation and water pressure regulators
should be installed in the main line or in front of the housing if
water pressure exceeds manufacturers’ maximum water
pressure: 75 PSI. Installers should make sure filters and
replacement filters are the correct length and are not too long
so as to not cause undo strain and stress on the housing.
CAUTION: All filtration systems contain other parts that have a
limited service life.
Exhaustion of the service life of those parts often cannot be
easily detected. Commonly, it is only after leakage has been
observed or water damage has occurred that one is made
aware that the service life has been exhausted
