4.) Install the system grates and secure each grate to the frame crossbars with
grate lockdown bolts. Hex bolt lockdowns should be installed with a flat
washer. Ensure the grates are aligned with an equal distance to each
sidewall before tightening the bolts.
Note: Frame Guards if specified they must be installled before the grates
and prior to the concrete pour.
5.) Install the construction covers to protect the grating and prevent
construction debris from entering the channels.
Channel Adaptors
A Channel Adaptor is required to make male-male connections (channels sloping
towards each other). Install the U-shaped adaptor between the two male ends and
cut along the scored lines to match the height of the connecting channels. Secure
the adaptor with 4 sets of 10-24 bolts and nuts provided. A matching block is
provided with each adaptor to fill the gap created between the installed grates.
Trim the block along the scored lines to match the finished grade, and secure the
block to the frame crossbar with 3/8" hex bolts and flat washers.
FIG. L
Note: Female-female connections (channels sloping away from each other)
attach directly and do not require an adaptor. If desired the installer can fill the
slight recess created on the inside of the connection with a bead of silicone
caulk.
Channel Spacers
Under certain conditions the cumulative frame length may exceed the cumulative
channel length, resulting in the frame overhanging the channel. If this occurs, insert
3/4" wide U-Shaped male-female Channel Spacers to extend the channel length to
match the frame length. Channel spacers can be added as needed at any point in
a run.
