3.
See Fig. 8, 8A. Make sure to align the drain saddle hole to the drilled hole perfectly.
Mis-aligning these two holes will block the drain water and cause membrane damage.
Attach the drain saddle to the drain pipe and tighten the two screws evenly.
4. Once the drain saddle is secured, push 1/4” black drain tubing into the Quick Connect fitting on the
saddle.
DO NOT
use a “Insert” on the drain tubing.

Step 3: Drill A Hole For The RO Faucet
Drill 1/2” diameter hole for standard RO faucet.
(Air-Gap faucet: drill 1”D hole.)
For best results use a 1/2” carbide-tipped masonry drill bit.
Wear safety glasses to protect your eyes while drilling the faucet hole.
Note:
No need to drill a hole if an existing hole is available:
a)
Spare hole:
If there is a spare hole in the sink covered by a chrome cover, simply remove the chrome
cover and install the RO faucet there.
b
)
Spray hose:
If the spray hose is not in use, remove the hose, and mount the RO faucet there. Remember
to plug up the outlet under the main faucet. If the spray hose uses a diverter at the base of the spout, be sure
to remove it to avoid trouble later on.

Hanging faucet:
If drilling a hole is not feasible (i.e. rental home, drill tool not available etc.), the faucet
can just hang on the cabinet door or wherever that is convenient. Be creative!
When drilling a hole for the RO faucet, choose a location that looks good, works well, and is most con-
venient for dispensing pure water. An ample flat area is required for the faucet base so that the faucet
can be drawn down tightly.
1.
Faucet location:
Make sure the faucet stem will be accessible from below when the hole is drilled.
If space is not available on the upper sink area, the faucet can be located on
the counter top by the
edge of the sink. If the counter top is ceramic tile, the method for drilling the hole will be the same as
for porcelain sinks.
2.
For Stainless Steel Sink:
Before using a 1/2” carbide drill bit, an indent should be made with a
center punch to keep the drill bit from walking. A small pilot hole will also aid the drill bit.
