Installation Guide
Undermount Installation Instructions
1: PREP COUNTERTOP
1. Position the template (provided with your sink) front to rear so the sink 
will not interfere with the cabinet; secure with tape.
2. Trace the template and remove. Dry t the sink to verify the 
measurements.
3. Following the countertop manufacturer’s instructions, carefully cut the 
countertop on the inside of the traced line.
4. Locate and drill the mounting holes, following the countertop 
manufacturer’s instructions. Holes should allow even spacing of 
mounting brackets around the sink.
5. With the countertop inverted (upside down), fasten the mounting 
brackets to the countertop loosely.
IMPORTANT: The cabinet must be installed, secured, plumb, and level BEFORE 
installing the sink.
IMPORTANT: Superior Sinks undermount sinks should only be fastened to a solid 
surface countertop (i.e. granite, Corian® or Silestone®).
2: INSTALL COUNTERTOP

with denatured alcohol.
2. Apply a narrow bead of silicone adhesive sealant evenly all around the 
top of the sink anges.
3. Position and align the sink over the countertop opening. Press silicone 
onto countertop.
4. Tighten fasteners until mounting brackets are snug against sink. Check 
alignment of sink to the countertop opening.
5. Tighten down fasteners evenly. Be careful not to over-tighten.
6. Immediately remove excess sealant.
IMPORTANT: The enclosed cutout template will create a countertop opening with 
a minimal (1/8” or less) reveal. It is recommended that you discuss this with your 
installer and agree that this nished appearance is the desired effect. Superior

during installation. Be sure to inspect the sink for damage prior to beginning 
installation.
