Check Space & Level
Use a level to check the counter/benchtop – if not level, have rectified. Ensure there is adequate space
for tapware (including a splash back 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.

IF COUNTER / BENCHTOP IS SUPPLIED WITH CUT-OUT, SKIP STEPS MARKED WITH*
Mark Cut Out *
Carefully mark out the template (or follow drawing instructions). Once the hole is marked out, use the
template to conduct a final check before cutting.
IMPORTANT
For topmount sinks only, you can trace the sink itself to mark your cut out, the hole must be cut 10mm /
3/8” inside the marked line.
Cut & Finish Hole *
Re-check the position and cut out shape you have traced before cutting. Ensure there are no obstacles
below that might interfere with cutting. Drill pilot holes to accept an appropriate cutting tool for the
counter/benchtop material (wear suitable personal protection equipment).
Masking
If using a sealant, masking is necessary to prevent sealant overrun. It is recommended that the edge of
the sink and the edge of the cutout are both covered with a suitable masking tape. This tape should be
removed within 2 days of application.
Trial Fit The Sink
Check that all clips are folded in so they will adequately clear the cut-out. Carefully position the sink into
the cut-out to make sure it fits 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.
Plumbing & Tapware
IMPORTANT - Connections to plumbing should always be done by a licensed plumber.
Fit supplied basket wastes to sink bowls. Install tapware according to manufacturer’s
instructions. Care should be taken when fitting wastes to the sink. Follow the instructions
provided with the wastes.
Additional Sealant (Optional)
Apply additional sealant / caulking compound around the join where the counter/
benchtop and the stainless steel sink meet. Check that the caulking product is mildew
resistant and is suitable for use on the counter/benchtop material and also is suitable
for use on stainless steel. Clean away any excess before it dries. Note: Additional sealant
should always be used if gaps are apparent after the sink has been clamped to the
counter/benchtop
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‘ Bond: For minimum 1” / 25mm thick material. Bond it to the underside of the
counter/benchtop with a structural high strength epoxy compound. NOT RECOMMENDED
TO BE USED WHEN FITTING SINK TO THINNER COUNTER/BENCHTOPS.
‘C‘ Bolt: For minimum 1” / 25mm 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.
If you have any doubts, confirm the correct mounting method for your material by
consulting the counter/benchtop supplier.
Above shows sandwich method
where sink is clamped between a
lower support board (with routed
edge) and the upper counter /
benchtop using method A.
Above shows how threaded rod
and timber bearers may be used
to clamp the sink in place while
fastening to the counter / benchtop
using methods B and C.
Do not overtighten as this may
damage the sink.

UNDERMOUNT ONLY
Fitting The Sink
Position and align the sink correctly in the cutout and lower it onto the counter/benchtop.
From underneath, install and tighten the clips with a screwdriver using a suitable
tightening sequence (tighten from the centre of the sink to the outer edge) until the sink
is secure and no gaps are visible. Take extra care if using power tools as over-tightening
can damage clips. The clips included with the sink require a minimum counter/benchtop
thickness of 1” / 25mm. If fitting into a thinner bench top, timber blocks or similar should
be installed between the bench top and the clip.
