d
A length of "D" gasket is attached to each section
(Figure 7). This gasket MUST be installed to the unit
base section.
IMPORTANT
The gasket is to be installed in an arc shape with the ends
lower than the center, so that any moisture that may reach the
gasket will be drained to the outside of the unit.
e
Handle units with curb-ready bases and vestibules so
the lifting bracket can be removed after the unit is
placed on the curbing.
Note: Remove the lifting bracket that projects inward over
the curbing. Save the self tapping screws. When the
adjacent section is placed in position, use self
tapping screw to secure the bases together.
f
For certain Skyline Plus units, use the provided
section joining plates to fasten sections together.
Space them as shown in
¼"-14 x 1" self tapping screws, drill screw the joining
plates into the frame channel on each section, keeping
unit sections tight together. Follow instruction
drawing included in the assembly kit.
