Make The Faucet Mounting Hole; Mount The Faucet - Water Factory Systems N4000 Series Installation, Operation And Maintenance Manual

The customer should be consulted before determin-
ing faucet location. The faucet should be positioned
so that it empties into the sink and the spout swivels
freely for convenience.
If the sink already has a hole provided that
can accommodate the RO faucet, then no drilling is
required and you can proceed to the section on
mounting the faucet.
With the customer's permission, sprayers can
NOTE:
be disconnected to provide a suitable hole for the
RO faucet. A pipe cap or plug will be required to
seal the sprayer connection. A special kit which pro-
vides a sprayer for the end of the kitchen faucet and
an assortment of caps and plugs are available.
H. Make The Faucet Mounting Hole
IMPORTANT: It is mandatory that safety glasses
be worn during sink hole drilling operations to
prevent eye injury.
Before starting the hole making operation, always
check below the sink so that nothing interferes with
mounting the faucet such as reinforcing ribs, support
brackets or cabinet construction.
Stainless steel sink, faucet with or without air
gap module:
Recommended tools:
• Center punch
• Variable speed drill and high speed drill bits
• Greenlee chassis punch 7/8" hole size (alternate 9/16"
size may be used for faucets without air gap module)
Procedure:
A) Center punch a small indent at the desired faucet
location.
B) Slowly drill required pilot hole for the chassis punch.
C) Set up the chassis punch per instructions and tighten
nut to cut the desired hole size.
D) Clean up sharp edges with a file if necessary.
Porcelain/Enamel/Ceramic on sheet metal or cast
iron base; faucet with or without air gap module:
Recommended Tools:
• Variable speed drill
• Relton porcelain cutter tool set 7/8" size (alternate
9/16" porcelain bit may be used for faucets without
air gap module)
• 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
chipping 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 porce-
lain 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 cut-
ter 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.
