Step 3. Install the Cold Water Supply Faucet Adapter
1.
Turn OFF the COLD water supply valve to your kitchen faucet.
2.
Turn ON the COLD water on your kitchen faucet to release all the pressure, and completely drain the cold
water until the water flow stops.
3.
Place some towels underneath the cold water supply valve and then disconnect the faucet supply tube from
the cold water supply valve.
4.
Wrap male threads on both cold water supply valve and the water supply adapter 4 to 5 times with plumber’s
(Teflon) tape.
5.
Install the water supply adapter on the cold water supply valve. Do not over-tighten.
6.
Install the faucet supply tube to the water supply adapter.
7.
Connect the white ¼” tube to the water supply adapter by inserting the tube firmly and pushing until the tube
end contacts the stop. Gently tug the tube backwards to assure a secure connection. Do NOT connect the
other end of the tube to the RO system water inlet at this time.
8.
Keep the COLD water supply valve OFF until the RO system installation has been completed.
Step 4. Install the Sink Faucet
Tools required for this step: An electric drill, a 5/8” carbide bit, a small adjustable wrench, a center punch, a pencil, a rat-
tail file.
1.
Examine the sink. If it has an existing hole for mounting a faucet, skip to Step 4. (6).
2.
Locate and mark the spot you wish to install the faucet. Make sure it does not interfere with operation of the
main faucet and that there is clearance for plumbing and mounting hardware directly below it under the sink
or countertop. If you have a stainless sink, go to Step 4. (5)
3.
If you have a concrete sink with a thickness of less than 1”, the faucet can be mounted directly to sink. If the
thickness exceeds 1”, the faucet must be mounted directly on the countertop or a faucet with an extended
shank must be used.
Tool substitution: Use a 5/8” masonry bit to drill the concrete sink.
4.
If you have a porcelain enamel or ceramic sink, it is
strongly
recommended that a professional install the
faucet to avoid chipping and damaging the sink finish.
5.
Mark the spot chosen for the faucet hole with the pencil. Use the center punch to slightly indent the spot
(the center punch is unnecessary for concrete sinks). Use the 5/8” bit and drill the hole. Use the rat-tail file
to smooth any burrs or rough edges on the hole.
6.
The sink faucet may now be assembled to the sink or countertop using the assembly procedure shown in
Figure 2. Your faucet may have the poly tube factory pre-attached. If so, do not connect the tube to
anything at this time. If the tube is not pre-attached, do not attach the poly tube to faucet at this time.
