Installing your filter
IMPORTANT
-
- Install or store where it will not be exposed to temperatures below
freezing or exposed to any type of weather. Water freezing in the
system will damage it.
- Recommended installation is under the sink. However, the unit can
be installed in a remote location, up to 20 feet away from the sink.
Additional installation materials may be required.
-Be sure there is room underneath the sink to make the needed
connections.
-If installed under sink, leave enough tubing in place during
installation to be able to move unit to floor for ease at servicing and
making filter cartridge changes.

Feed Water Supply
1. Close the cold-water supply valve under the sink.
2. Unscrew the flexible tubing from the supply valve that connects to
the COLD-water riser.
NOTE: If the cold water shut-off valve fails to turn off the water,
house water supply can be turned off at the main water supply.
3. Disconnect the threaded nut at the
connection, and with the flat washer in
place, thread the feed water supply adapter
onto the connection and tighten. Connect
the Red Tube to the water supply adapter
with the treaded nut and tighten. DO NOT
OVER TIGHTEN.
4. Thread the needle valve into the adapter
tightly and turn the handle clockwise all the
way in. Open the main water supply valve
and several house faucets to purge air from
the system. Close faucets when water runs
smoothly. Turn on cold water supply to the
sink faucet and check for leaks

-Do not install on HOT WATER. Temperature of water supply to the
filter system must be between minimum of 40°F and maximum of
90°F.
- The assembly can stand up in the sink cabinet or can be hung on
screws.
- Use PTFE (Teflon) tape for the fittings and do not overtighten.
COLOR CODE FOR TUBING
Use the color-coded tubing to make connections as follows:
A. Red tubing connects water supply adapter to inlet side of the
assembly
B. Blue tubing connects the faucet to the outlet side of assembly

Faucet Connection
1. Carefully select the faucet location making sure:
•the faucet base fits flat against the surface at the selected
location so the gasket will seal.
•the faucet stud will be accessible from below once the hole is
completed.
2. Use an existing predrilled hole on sink or drill one of ½ inch diameter.
3. Slide Escutcheon chrome plate and large rubber gasket onto stem of
faucet and place faucet onto sink with stem going through the hole.
4. Place small rubber gasket, plastic washer, metal ss washer and star
lock washer over threaded stem of faucet and tighten nut from
under the counter surface to lock the faucet into place. DO NOT
OVER TIGHTEN.
5. Connect the Blue Tube to faucet stem under the counter using quick
connect type connector and tighten.

Startup Procedure
1. Check to see all connections are made.
2. Check that all sumps are secure using the housing wrench provided.
3. Slowly turn on water by turning the needle valve counterclockwise.
4. Handle of the faucet should be perpendicular to the spigot (closed).
5. Check for leaks.
WARNING: Before using filter system for the first time, the system must
be purged for several minutes to flush out black carbon fines. Initially,
the water may contain tiny air bubbles and taste slightly sweet this is
normal and harmless, and will clear up after flushing.
Connection to the Filter Assembly
Quick Fitting
Your filter comes pre-assembled with filters. You only need to attach the
quick fitting elbow connectors to inlet and outlet of the filter assembly
and insert the tubes in these elbow connectors and the system will be
ready for use. Remove the color-coded lock pins before inserting the
tubes, and replace after you are done.

1. Shut off the feed water to the system by turning the saddle valve on
the water supply adapter clockwise until it stops.
2. Press down on faucet handle to relieve pressure.
3. Allow 2-3 minutes for pressure in the system to drop.
4. Remove the filter sumps with the housing wrench by turning the
sump to the left (counterclockwise). If the O- ring in the sump is
stretched or worn, it should be replaced to maintain a proper seal.
5. Remove the old filter and gaskets (if any) and insert the new filter.
6. Replace the sump onto the cap by turning it to the right (clockwise)
until the O-ring makes firm contact, like an oil filter on a car. DO NOT
OVER-TIGHTEN.
7. Turn on feed water to the system by turning the saddle valve at the
water supply adapter counterclockwise.
8. Remember to flush the carbon fines.
