TheDrainSaddleisusedtoconnecttheDrainLinetothedrain
pipeunderthesink,toallowthesy󰏭emtoushcontaminants
down the drain.
TheDrainSaddleisdesignedtotarounda󰏭andard1½”OD
(outer diameter) drain pipe. The Drain Saddle should always be
in󰏭alledabove(before)theP-Trapandona󰏭raightverticalor
horizontal section of pipe.
Toavoidcloggingthedrainlinewithdebrisdonotin󰏭allthe
Drain Saddle after the drain pipe meets a garbage disposal or
dishwasher drain. Refer to the image below to see ideal Drain
Saddle locations.
Please contact us if you need help locating a drain saddle
placement.
1. Once you have found where your Drain Saddle will go
on the Drain Pipe make a mark for the opening there with a
marker or pencil.
2. Use your drill and an appropriate ¼” (6.35mm) drill bit to
drill a hole at your mark. Be careful to drill through one side
ofthepipeand󰏭abilizeyourpipeswhiledrillingtoavoid
damaging them.
3. Find the half of the Drain Clamp with a hole in its center.
Then remove the backing from the Foam Gasket (the foam
circle at the center of the Gasket is disposable). Make sure to
align the Foam Gasket hole with the Drain Clamp hole and
󰏭icktheadhesivesideoftheGaskettotheinnerwallofthe
Drain Clamp half.
4. Take the half of the Drain Clamp without the Foam Gasket
and insert a nut into the recess on each side.
5. Position both halves of the Drain Clamp on the drain pipe
with the clamp’s opening aligned over the drilled hole. The
Foam Gasket will be between the drain clamp and the drilled
hole. Push your ¼” drill bit through both holes (the Drain
Clamp hole and the hole in the Drain Pipe) and remove to
verify that the clamp is properly aligned with the hole you
drilled.
6. Secure the Drain Clamp halves together in place on the
Drain Pipe. Screw the bolts through the Drain Clamp half with
theFoamGasketandintothehalfyouin󰏭alledthenutsinto
(Do not over tighten. Make sure there is equal space on both
sides between the Drain Clamp halves).

CAUTION
•Thecutsonthetubingmustbestraightandsmoothwithoutanybrokenedgesaectingthesealing.
• Make sure that the tubing is not deformed after being cut and inspect the O-shaped gasket for any damages so that no water
leakage occurs.
5) Installation of the pure water outlet tubing
A. Use a tube cutter to cut an appropriate length
of the matching white ¼” tubing.
B. Insert one end of the tubing into the pure
water outlet port of the system. After the tubing
is inserted in place, insert the ¼” lock clip in the
position of the quick-release connector slot.
C. Connect the other end of the tubing to the
faucet through the quick-release connector.
4) Installation of the waste water tubing
A. Use a tube cutter to cut an appropriate length
of the matching red ¼" tubing.
B. Insert one end of the tubing into the waste
water outlet of the system. After the tubing is
inserted in place, insert the ¼” lock clip in the
position of the quick-release connector slot.
C. Connect the other end of the tubing to the
drain saddle and secure connection.
3) Installation of the inlet water tubing
A.Cutaproperlengthof⅜”tubingwithoneend
connected to the 3-way connector valve joint.
B. Insert the other end of the tubing into the
waterinlet(IN)port,andtheninsertthe⅜”lock
clip at the slot of the quick connect connector.
NOTE: Make sure to insert the tubing as far as
possible for a secure connection.
2) Remove plugs from port of system
A.Useyourngertopressdownonthecollet
(loose ring around plug).
B. Use your other hand to pull out the plug from
pure water port.
C. Repeat step A and B to pull out balance plugs
from inlet water port and waste water port.

3.8 Illustration of the completed installation
Cautions:
1)Aftertheinstallationiscompleted,checkandbesurethatnotubingorconnectionsleakwaterduringushingprocess.
2) The drain water outlet tubing must be connected to the drain and secured properly. Do not use a water storage device to
collectthedrainwaterincasewaterspillsduetotheproduct’sautonomousush.
The RO Faucet may be in󰍰alled on any at surface. Check the underside of your
in󰍰all location for any interference by making sure that drilling a hole will not
damage any pipes or wiring underneath the countertop or sink. Check to be sure
there is enough room for the Threaded Faucet Stem.
NOTE! For drilling you mu󰍰 use an appropriate drill bit and drilling method
for the material of your sink and counter top. Dierent drill bits are required for
󰍰ainless 󰍰eel, porcelain, granite, etc.
You may use an exi󰍰ing hole in your counter or sink or drill a new hole (if using
an exi󰍰ing hole begin at 󰍰ep 2). Make sure the Base Plate is big enough to cover
the hole you use.
Porcelain Sink
A proper porcelain ½” drill bit is 󰍰rongly recommended to prevent chipping
if you are drilling on a porcelain sink. Drill slowly to avoid chipping during the
initial cutting of the porcelain.
Stainless Steel Sink
1. Use a proper ½” drill bit (depending on your sink / counter material) to make
a hole for your RO Faucet.
2. Insert the Pre-Assembled Base Plate & Rubber Washer (see design) onto the
Threaded Faucet Stem at the base of the RO Faucet. Then put the Threaded
Faucet Stem through the newly drilled or pre-exi󰍰ing hole. Make sure the RO
Faucet sits in the center of your new or exi󰍰ing hole.
3. Under the sink in󰍰all the Rubber Washer and the Tension Hand Screw (see
design) onto the Threaded Faucet Stem. Make sure they are in󰍰alled all the way
up the 󰍰em.
4. Attach the Union Connector to the Threaded Faucet Stem, and then insert the
¼” White Tube into the Union Connector.

4.1 Use of the system for the rst time
Afterthewatersupplyhasbeenopened,andthepoweristurnedonforthersttime,thesystemwillstartautomaticallyush
for5minutes,thenproceedtomanuallyushbyturningonthefaucettorunwaterforanadditional30minutesuntiltheoutlet

NOTE: Whenthesystemhasbeenunused(faucetturnedo)for24hours,thesystemwillautoushfor20seconds.
CAUTION
Duringtheush,besuretocarefullychecktheconnectionofeachpartofthesystembywipingtheconnectorswithtissueand
checking if the tissues get wet. Make sure all tubing is installed correctly and securely.
Aftertheushiscompleted,turnotheROfaucetandmakesurethesystemisnotleaking.Thiscompletesthestartupprocess
of the unit.
4.2 Routine Maintenance
1)Ifthesystemisnotinuseforalongtime(morethanoneweek),pleaseturnonthepurierfaucetrst,turnothewater

and store it in the refrigerator / room for fresh-keeping (do not put it in the freezer), so as to reduce bacteria breeding - keep
awayfromdirectsunlight.Forre-use,itisrequiredtoushwaterfor10minutesbeforeusingthesystem,otherwiseyouneedto

theindicatorlightorremindinginformationofltercartridgelife.
4.3 Cautions
1)Onlyuseauthorizedoriginalltercartridgesforreplacement.
2)Theactualperformanceandservicelifeofeachltercartridgedependsonthelocaltapwaterqualityanddailyusage.
