Bracket x 1
Filter Cap x 1
Filter x 1
Bracket Mounting Screw x 4
3/8” Water Supply Line x 2
Space: Make sure there is sufficient space under the counter for installation
The system is best installed under the kitchen sink. But if that is not feasible you
can install the system anywhere where there is a cold water supply with sufficient water pressure.
Note: System is primary used as a POU (point of use) system. It is not recommended
to connect it on a location that has multiple outlets.
Mounting: Recommend mounting the system on the wall; please leave minimum 6 inch
of space underneath the filter to make sure filter cartridge can be taken down
easily for filter replacement.
Step 1: Disconnecting the Existing Cold Water Supply Line
Locate the Cold water supply valve under the kitchen sink
(the round or oblong handle on the right side). Turn off
the incoming cold water completely by turning the shut off
handle clockwise.
Note: If the cold water shut off valve cannot turn off
the water, the main water supply to the house must
be shut off for the installation.
Turn the faucet handle to
the ON position to release
the remaining water.
Disconnect the existing
fittings and hose from the
cold water supply valve to
the faucet.
Step 2: Mounting the Bracket
Hold the system with the filter label side facing you. Look
on top of the cap to make sure the arrow is pointing
towards your right. That arrow indicates the water flow
Screw the bracket to the top of the system cap with the front
end facing the same side as the filter label. Please use the
front holes for the two screw holes on the backside.
With the appropriate nails or hanger, mount the system to
the wall. Make sure to mount the system close enough to
connect to both the cold water valve and connector to the
faucet. Leave minimum 6 inch of space underneath the filter
for filter change.
Step 3: Connecting The System
Connect one end of the 2nd water
supply line to the side of the cap that
indicate “OUT” and connect the other
end of the same water supply line to
the sink faucet cold water input.
Connect one end of the 1st water
supply line to the side of the cap that
indicate “IN” and connect the other
end of the same water supply line to
the cold water valve.
Step 4: System Start-Up
Turn on feed water:
Slowly, turn on your
Cold water supply. Turn
counter-clockwise to
allow the raw water to
enter the system.
Check for leaks!
Turn on the cold water
faucet and let it flush the
new system for up to 5

The system requires very little maintenance. Just change the filter cartridges regularly as
indicated on the filter label (Replacement time may vary based on the condition of source
water). Keep the system indoors away from extreme heat or cold temperatures, and run
the system within its reasonable output capacity (i.e. allow the system to rest at least a few
hours a day).
