ATTACH LOWER EDGE OF PANEL TO BASEBOARD
Use customer-supplied dimension lumber as a retaining
board for the lower edge of the panel.
The retaining board must be
at least 1" x 2"
to adequately
secure the panel to the baseboard. See the diagram below
for an example.
CAUTION:
Do not attempt to attach the panel to the
baseboard during stormy or windy conditions or when
such conditions are expected.
Complete these steps to attach the lower edge of the panel
to the customer-supplied baseboard.
1. Using the supplied-crank handle, roll the panel up to
within 2" of where it will seat into the channel created
by the ribbon boards.
2. Move to the bottom of the panel and with assistance,
evenly stretch the panel end-to-end along the
baseboard.
3. Take the first section of customer-supplied retaining
board and place it against the panel and the baseboard
to hold the panel in position.
NOTE:
Evenly and gently pull the panel edge down to
remove wrinkles.
Applying too much force may bend
the panel conduit.
