Installation Instructions
All installation works to be carried out by
competent personnel - install as complete
unit.
Serpentine bench / seat on tubular bases
(surface & sub-surface fix)
1.
Install suitable foundation pads (see
illustration) each with top face at ground
level or 100mm below finished ground
level for sub-surface fix.
2.
Fully assemble bench / seat following
instructions on pg. 5 of this document.
3.
Once assembled position bench / seat in
correct orientation with bases centrally
on foundation pads; then mark hole
positions through base plates.
4.
Remove the bench; drill holes Ø14mm
x 130mm deep (surface fix) or Ø12mm
x 75mm deep (sub-surface fix) or as
manufacturer’s recommendations.
5.
Clear debris from holes.
6.a
. (Surface fix) Fill the holes to within
approximately 35mm from the top with
Hilti HY150 resin (or similar). Lift the seat
(with threaded anchor rods/capnuts in
place) and carefully lower the anchors
into the holes, leave for two hours before
using.
6.b
Using a torque wrench, tighten nuts and
washers over flange plates to 30Nm to
fasten down the bench.
7.
(Sub-surface fix) Reposition bench /
seat unit and fix to foundation pads
using 4 no. zinc-coated M10 x 75mm
sleeve anchors tightened to 50Nm (or
as per manufacturer’s instruction).
Ensure bench remains level during fixing
process.
8.
Check level & re-instate ground level if
necessary (sub-surface fix).
IMPORTANT NOTE
Ensure that stainless steel is protected
during site cutting of stone – contamination
from disc cutters will produce corrosion on
stainless steel components.
