The last component can now be installed with a
bead of DOW 804 adhesive sealant around the
perimeter of the WMS junction box cover. First
remove the adhesive backing on top of the WMS
spacer tube. This will adhere to the bottom side
of the WMS junction box cover. Using a caulking
gun, run a bead of DOW 804 around the entirety
of the perimeter of the WMS junction box cover.
Carefully place the WMS junction box cover
so that the edge of it goes around the outside
of each set of junction boxes. The side of the
junction box cover should go over and around
the WMS wire conduit to ensure a watertight
seal. Apply pressure to the junction box cover to
complete the installation.
Repeat this process until you have fully installed
all modules on the seam before moving onto
the next seam. It is important the roof surfaces
remain clean during the application process.
