b) Slowly drill the required pilot hole for the
chassis punch.
c) Set up the chassis punch per in struc tions and
tighten nut to cut the desired hole size.
d) Clean up sharp edges with a file if necessary.
Porcelain/Enamel/Ceramic on Sheet Met al or Cast Iron
Base; Faucet with or without Air Gap Module:
Recommended tools:
• Variable speed drill
• Relton porcelain cutter tool set 7/8" size
(al ter nate 9/16" size may be used for air gap or non
air gap faucet)
• Plumber’s putty
It is important to understand what is in volved in this
procedure. First, the glassy layer of porcelain must be
penetrated through to the base metal. Second, a center
disc of porcelain must be re moved while protect ing the
sur round ing porcelain against chip ping or fracturing.
Third, the base metal must be drilled through to com-
plete the hole.
Procedure:
a) Mark the center for the 7/8" hole
b) Form a shallow putty dam around hole area
and fill with enough water to lubricate carbide drill
bit.
c) Carefully drill pilot hole through por ce lain/enam el
and base metal using carbide type pilot drill.
IMPORTANT:
Always operate drill with light
pres sure at slow speed (300-400 rpm)
d) Insert pilot tip of spring-loaded por ce lain cutter
into pilot hole.
e) Drill porcelain/enamel using spring-load ed por-
ce lain cutter, making certain a com plete ring has
been cut through the por ce lain/enamel to the
metal base.
f) Change to the metal cutter. With slow speed and
light pressure, cut away the inner por ce lain/enam-
el disc down to base metal. Make certain that the
cutter does not touch out er rim of the cut porce-
lain/enamel. Con tin ue with this bit to cut through
metal until sink has been completely penetrated.
IMPORTANT:
When using a porcelain cutter it is
critical to take precautions that it
is always in a sharp ened condition.
Dull cutters are known to chip sinks.
2. Mount The Faucet:
NOTE:
For Basement Installation Without Air
Gap Module See Figure 6, Page 16.
Under Counter Installation with Air Gap Faucet:
a) Familiarize yourself with all com po nents shown
in the air gap faucet diagram.
b) Disassemble hardware from the threaded nipple,
except for chrome base plate and rubber washer.
NOTE:
Rubber washer may be replaced with bead
of plumber’s putty for neater ap pear ance.
c) Connect length of standard red 1/4" tub ing to
smaller barb on air gap faucet. Push on firmly until
it seats.
d) Connect length of black 3/8" tubing to larger barb
on air gap faucet. Push on firmly until it seats.
e) Feed the air gap tubing and threaded nip ple
through sink/counter mounting hole and orient
the faucet as discussed with the customer.
f) From below sink/counter assemble the white
spac er (open end up, open side toward air gap),
flat washer and hex nut on threaded nip ple and
tighten by hand.
g) Back off on hex nut just enough to slide slotted
washer between white spacer and un der side of
sink/counter (with open side of slotted washer
closest to air gap tubes)
h) After rechecking faucet orientation, tighten hex
nut (9/16" wrench or deep socket) until faucet
feels secure.
i) From above the sink make any minor ori en ta tion
cor rec tions by turning the faucet with a padded
adjustable wrench.
Note:
Flats on chrome faucet may be used for
tight en ing with an adjustable wrench. Use
care not to mar chrome finish.
