Note:
Pull all wires through conduits before mounting the base. See Electrical Planning for
wiring requirements.
When installing the Portal TI+ frame, it is recommended that the concrete pad be undercut,

undercut pad size should have the following dimensions:

To ensure the base is installed at the proper height, the lower cross braces should be flush
with the concrete surface (the braces are located 6 in. from the bottom of the frame). Ensure
the base frame is level and place the plastic base cover over the frame after the concrete has
set.
