SECTION IV. INSTALLATION STEPS
All plumbing should be done in accordance with state
and local plumbing codes.
NOTE
: Some codes may require installation by a
licensed plumber; check with the local plumbing
authority prior to installation.
In restricted under–sink areas, it may be easier to
install the faucet first. Allow adequate tubing lengths
for any final component position.
A. Faucet Installation –The faucet contains an
anti–siphon air gap. While the system is producing
water, the drain water flows from the R.O., through
the air gap and then to the household drain. The
purpose of the air gap is to prevent water in the
drain from backing up into the R.O. Drinking Water
System.
The easiest installation is to use an existing spray
attachment hole. If the spray faucet hole is not
available, then the sink top must be drilled.
1. Mark the location of the center of the faucet
base.
2a. Drilling a stainless steel sink:
•Center punch the hole to provide a starting
point for the drill.
•Start with a smaller drill as a pilot, and then
drill a ½" diameter hole to accept the bolt of
a 1¼" Greenlee Hole Punch (1¼" chassis
punch).
•Clean away any chips.
•Install the punch and tighten the nut to cut the
hole.
•Deburr any sharp edges.
2b. Drilling a porcelain sink:
It is best to use a special 1¼" diameter cutter
designed for porcelain. A carbide tipped
masonry bit is a second choice.
•Place a piece of tape over the area to be
drilled to help prevent chipping.
•Drill a pilot hole for the porcelain cutter. Use
the pilot drill supplied with the kit or a carbide
tipped drill.
•When drilling the 1¼" hole, drill slowly and
carefully; the porcelain chips easily.
•After drilling, clean the area well. Iron filings, if
left in place, can cause rust stains.
2c. Drilling a counter top:
NOTE:
The counter top must be less than 1¼"
thick. Treat ceramic tile as porcelain until the
tile is penetrated, then use the carbide tipped
metal cutter.
Formica counter tops may be drilled with a
good 1¼" wood bit; drilling a
3
/
32
" pilot hole will
help keep the bit going straight.
3. Assemble the

” Screws & Toggle Wings
into the Faucet Base. Adjust the Wings
approximately 1” plus the thickness of the
mounting surface away from the bottom of the
Faucet Base.
