10. Apply a
final
layer of weather-
resistant
self-leveling
sealant (such
as NovaLink SL).
a) Fill the last ½” of the roof-split
gap with self-leveling sealant
until it is level with the top of
the blower/filter roof flange.
Back-fill along the entire
length of the roof-seam to
ensure there are no bubbles or
gaps in the sealant. The final
outcome should look similar to
what is shown in Figure 20.
b) Repeat for each roof split gap
(between the blower/filter and
coil sections).
c) Let cure for at least 3-hours
to ensure sufficient skin-over
(longer if very cold/dry).
11. Prepare the roof-split covers.
a) Clean the roof-split cover
angles with isopropyl alcohol,
on the side to which the VHB
tape will be applied.
b) Apply 1” VHB tape to the entire
back of the roof-split angles as
shown below.
c) Dog-ear the tape on each end
of the roof-split cover angles
(Figure 21).
d) Prep all roof-split cover angles.
12. Install the roof-split covers.
a) Starting from one side of
the unit, install the roof-
split covers as shown in the
attached drawing (removing
VHB tape backing by pulling
on the previously-prepared
“dog-ears”).
b) Press the roof-split covers
firmly into place, ensuring no
gaps between the tape and
coil section.
c) Caulk the gap between the
roof-split covers and coil
section as shown on the
attached drawing.
