To prevent dust from accumulating, be
sure to install the T
OPO panels only after
all other construction activity has been
completed.
After unpacking the T OPO Panels and
prior to installation, spray and wipe each
panel with the provided anti-static spray
and lint-free towel.
Install panels surrounding Utility Circles
first. These panels have a curved notch
in one corner.
T OPO panels are designed to slip over
the tee easily yet have sufficient grip to
keep the panel edges in place.
In some cases, Panel Hold-Down Clips
may also be necessary to create a tight
fit between the panels and the grid. By
snapping a Panel Hold-Down Clip over
the bulb of the tee between two panels,
the clip keeps two adjacent panels
pressed tightly to the grid. Panel Hold-Down Clips should be installed
after two adjacent panels have been laid
in place.
After all T OPO panels surrounding
Utility Circles have been installed…
…install the remaining panels as indicated
on the 2-D drawing.
Note: T OPO Panels all have the same
shape. During installation, each panel can
simply be rotated until properly oriented
with the vaults and valleys of the T
OPO Grid.
If your installation includes T OPO panels
with preformed Utility Circles, note their
locations on the 2-D drawing and install
these accordingly.
