PORCELAIN/ENAMEL/CERAMIC ON SHEET
METAL OR CAST IRON BASE:
Recommended tools:
•
Variable speed drill
•
Relton porcelain cutter tool set 7/8" size
(alternate 9/16: size may be used for air gap
or non-air gap faucet)
•
Plumber’s putty
It is important to understand what is involved 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 removed while
protecting the surrounding porcelain against chip-
ping or fracturing. Third, the base metal must be
drilled through to complete the hole.
Procedure:
a)
Mark the center for the 7/8” hole
b) Form shallow putty dam around hole area
and fill with enough water to lubricate
carbide drill bit.
c) Carefully drill pilot hole through
porcelain/enamel and base metal using
carbide type pilot drill.
IMPORTANT: Always operate drill with light
pressure at slow speed (300-400 rpm).
d) Insert pilot tip of spring-loaded porcelain
cutter into pilot hole.
e) Drill porcelain/enamel using spring-loaded
porcelain cutter, making certain a complete
ring has been cut through the
porcelain/enamel to the metal base.
f) Change to the metal cutter. With slow
speed and light pressure, cut away the inner
porcelain/enamel disc down to base metal.
Make certain that the cutter does not touch
outer rim of the cut porcelain/enamel.
Continue 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 sharpened condition. Dull cutters are known
to chip sinks.
2. Mount the Faucet:
a) Familiarize yourself with all components
shown in 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 appearance.
c) Connect length of standard 1/4" tubing to
faucet. Ensure plastic insert is in tubing.
Push on firmly until it seats.
d) Feed the threaded nipple through
sink/counter mounting hole and orient the
faucet as discussed with the customer.
e) From below sink/counter assemble the
black plastic washer, star washer and hex
nut on threaded nipple and tighten by hand.
f) After rechecking faucet orientation, tighten
hex nut (9/16" wrench or deep socket) until
faucet feels secure.
g) From above the sink make any minor
orientation corrections by turning the faucet
with a padded adjustable wrench.
h) Install plastic ferrule and compression
nut on tubing.
Note: Flats on chrome faucet may be used for
tightening with an adjustable wrench. Use care not
to mar chrome finish
.
B. Install the Feed Water Valve and Tubing
The feed water valve supplied is designed for use
with typical cold water shutoff valves with flexible
hose connection to the faucet. Other hardware may
be required for a different cold water supply
configuration.
Feed Water Valve Installation
NOTE: For basement installations the existing feed
water tubing may have to be longer to reach feed
valve.
