FITTING THE SINK
Position and align the sink correctly in the cutout (some threaded
rod and timber bearers will help to clamp the sink in place) and either:
‘A’ Sandwich Method: RECOMMENDED FOR BOTH THIN AND
THICK COUNTER/BENCHTOP. Firmly fix a support board into / over
the cabinet and cut the sink hole so that the sink flange will sit
above the edge of the board. Slightly rout the edge so that the sink
flange will sit flush with the top surface. Test for fit. Install sink and
seal between flange and support board. Apply sealant to the
underside edge of the cutout on counter/benchtop material and
position it over the support board to sandwich the sink in place.
Fasten the counter/ benchtop securely.
‘B‘ Bolt: For minimum 25mm (1”) thick material. Bolt it to the
counter /benchtop using “molly” assemblies. Care must be taken
during drilling and tightening to avoid cracking.
NOT RECOMMENDED TO BE USED WHEN FITTING SINK TO
THINNER COUNTER/BENCHTOPS.

TF45e - Undermount Installation and Care Instructions
CHECK SPACE
Ensure there is adequate space for tapware (including a splashback if
specified). Check space for installation (underneath) and operation
(above). Particular care must be taken when a thick splash back is
used (it may interfere with tapware location and operation). Ensure
the cabinet will not foul the sink mounting flange or basins.
TEMPLATE *
Cut-out templates for your Oliveri sink are available online at
oliveri.com.au Use the product model number to find the template.
Some sink templates apply to both left-hand and right-hand models.
Ensure template is the correct way around for your model.
MARK CUT OUT *
Carefully mark out the template (or follow drawing instructions)
making allowance for any additional polishing back that is required
after cutting. NOTE: The template is the exact finished cut-out
size required.
CUT & FINISH HOLE *
Drill pilot holes to accept an appropriate cutting tool for the counter/
benchtop material (wear suitable personal protection equipment).
Cut inside the mark, allowing sufficient material for any sanding and
polishing back if required. NOTE: Accuracy of the cutout shape is
essential to ensure visual alignment with the bowl / basin
perimeter and so any accessories fit correctly.
TRIAL FIT THE SINK
Carefully position the sink against counter/benchtop to make sure it
fits the cut-out correctly. If the fit is not correct, remove the sink and
proceed with remedial work. Perform another trial fit after corrections
have been made.
APPLY SEALANT
Apply suitable sealant recommended for both the counter/benchtop
material being used and for stainless steel. Neutral-cure sealant will
not damage stainless steel. It may be easier to apply sealant after
preparing your clamping equipment. Do not allow the sealant to dry
before the sink is clamped to the counter/benchtop.
DO NOT INSTALL USING EPOXY ADHESIVES
Should a genuine warranty claim arise for a sink installed using this method, Oliveri will cover the
replacement cost of the sink only and not the cost of sink removal or reinstallation. If you have
any doubts, confirm the correct mounting method for your material by consulting the
counter/benchtop supplier.
ADDITIONAL FASTENING
The sealant alone may appear to bond the sink to the counter/ benchtop. However, when installing
your Oliveri undermount sink, it is important to always use methods A or B (below) to locate the sink
securely in the counter/bench top in conjunction with the sealant manufacturer’s instructions.
