to
speak
with
customers in advance and ask them to clean under
the sink to save time. If a basement installation is
advisable, check area to determine if extra fittings
or hosing are required. Upon arrival, it is a good
idea to check the condition of all plumbing for
potential leaks and advise customer so there will be
no misunderstandings in the event leaks occur.

Faucet installation
If the sink has a sprayer it may be disconnected for
faucet
installation.
(Installing
dealers
should
discuss this with customers.) A pipe cap or plug will
be necessary to seal the sprayer connection.
To make the faucet mounting hole (if sprayer or
second hole is not used), check below to make sure
the drill does not interfere with anything below.
Center punch a small indent at the desired faucet
location. (2” flat surface is required, not exceeding
1-1/4” in thickness.) Drill the required pilot hole for
the chassis punch and tighten nut to cut the desired
hole size. Clean up sharp edges.
The faucet should be positioned so it empties into
the
sink
and
the
spout
swivels
freely
for
convenience.
If
sink
has
a
hole
that
can
accommodate the RO faucet, no drilling is required.
Proceed with mounting the faucet.
