INSTALLATION INSTRUCTIONS – UNDERMOUNT SINKS

These instructions are for installing Foster

Undermount stainless steel sinks.

By Undermount, one identifies a sink that is

installed from below the countertop.

If you are installing a different kind of sink, for

instance a drop-in sink which is to be installed

from above the countertop, please refer to

instructions specifically made for these sinks.

The Foster Undermount sinks can be installed

with three different kinds of reveal: positive,

negative or no reveal. Each one will make

your sink look different (see drawing). The de-

cision on which kind of installation to use must

be done prior to commencing the job.

Positive reveal: the countertop edge is

approximately 1/8” back from the edge

of the sink, exposing thus the sink rim.

All the Foster undermount sinks feature

1” of nished rim.

Please note that if the positive reveal

is more than 1/8”, the cutting-board will

rest on the steel edge of the sink, and

not on the couter-top.

Zero reveal: the cut-out exactly matches

the bowl’s dimension.

Negative reveal: the countertop extends

over the edge of the sink on all sides by

approximately 1/8”. Prior to making the

cut-out for such an installation, please

check if the eventual accessories such

as colanders or cutting boards will t

properly.

WARNING: With a negative reveal the

steel bottom grid and wood cutting-

board cannot be used.

The template is supplied only as a guide. The use of the sink itself will ensure a more accurate

cut-out. Foster recommends that undermount sinks should be installed by a professional instal-

ler, in order to obtain the best results. Prior to commencing any operation, check your sink for

damage. Do not install a damaged sink. Please remember that it is the installer’s responsibility

to follow local plumbing and building regulations.

Please remember that the warranty will be considered void if these installation instructions

are not followed.

The following instructions refer to the installation of a Foster undermount stainless steel sink on a solid surface countertop only. The minimum thickness of the actual countertop material must be 1/2 “. However, the presence of a 1” counter-frame around the sink is advisable. Requirements vary for installation on granite, marble or stone countertops. Please check this out with your fabricator for more details.

STEP 3 (recommended for professional installers only) Attach the undermount clips Position the sink so that the reveal is equidistant. Then drill the holes for the brass inserts on the underside of the countertop. Use a drill bit with a stop block, in order to avoid drilling too deep, and eventually through the countertop. For ½” countertop material, the holes should be 3/8” deep. Use four clips on the long side of the sink, and three clips on the short side.
