SPECTRA Installation Instructions
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.
TEMPLATE *
Template supplied in carton is for undermount installation only. For topmount
installation see www.oliverisinks.com or use the drawing on the reverse page.
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
If you have traced the sink itself to mark your cut out, the hole must be cut
10mm 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). Cut just inside the template mark (or
10mm inside the sink tracing).
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.
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.
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.
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.

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
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 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.
