19. When all is satisfactory, release crane and
remove lifting eyes. Proceed to next stage
immediately
20. Engage the supplied 5.5mm ∅ HS drill bit with a
suitable power tool. To ensure that the underlay
is not damaged, either set the bit to the required
projection from the chuck, or mark the required
projection on the bit. The required projection is
110mm for the lower panel holes, and 135mm
for the upper panel holes.
21. Line up the drill bit through a panel fixing hole
(noting correct bit projection as at “ 20 ”), and
carefully make a pilot hole through the full depth
of the 9mm thick fixing bar below, taking care to
avoid drilling through the roofing underlay
(Useful tip: A piece of plywood or similar can be
placed between the fixing bar and the roofing
underlay to further help protect the underlay
during the drilling operation). Repeat this
process for all the panel fixing holes (six holes
for ST 4 and eight holes for ST 6), adjusting the
bit projection as required.
22. Once all the pilot holes in the upper and lower
panel fixing bars have been made, the panel is
ready to be screw fixed to the fixing bars using
the 6.3mm
∅
S/S self-tapping panel fixing
screws supplied (shorter for lower fixings,
longer for upper fixings). Ensure that the screws
are first inserted through the S/S/EPDM sealing
washers so that the EPDM side abuts the panel.
With a 9.5mm (3/8”) socket attached to a
suitable power drill: -
• Screw all screws just until the gaps
between the screw head washer and panel
close.
• Return and fully tighten each screw in turn
(without over-tightening), ensuring that the
panel fabric is not distorted.
•
Ensure that the panel is fully held down
onto the fixing bars at all fixings.
