2. Continuing to move clockwise around the outside of the skirt and now
measuring the full spacing distance, repeat Step 1, marking preliminary
mounting locations all the way around the outside of the skirt.
• Measure the spacing distance from the ideal location for the previous
L-Cell. Do not measure from the modified location if you relocated the
previous L-Cell because of an obstruction.
3. Proceed to the inside of the skirt and walk clockwise to the first L-Cell
location. Mark the preliminary L-Cell location to match the marked location
on the outside of the skirt:
• If you adjusted the outside location because of an obstruction, maintain
the offset configuration of the set (i.e., if you move the outside L-Cell in
the set from its ideal location, move the inside L-Cell as well).
• If there is an obstruction on the inside, follow the guidelines in Step 1 for
relocating the L-Cell. Verify the L-Cell on the outside can be relocated to
match the inside location and remark the outside location.
4. Continuing to move clockwise around the inside of the skirt, repeat Step 3,
marking locations all the way around the skirt.
5. Mark junction box locations on the inside of the skirt, centered between the
L-Cell sets. Each junction box can be wired to a maximum of two L-Cell sets
(four L-Cells total). Vertically, locate junction boxes approximately 6’ (1.8m)
above the foundation. This minimizes the possibility of interference with
L-Cells in the event the L-Cells cannot be placed in their ideal locations.
Ensure you have sufficient cable length and that a drip loop will be formed
by the L-Cell cables when wired to the junction box.
