Fastening the center adapter
1.
Use the five enclosed countersunk fasteners to screw the cen-
ter adapter in place.
The specific fasteners that are included will depend on the
specific stacking kit model being used. Use self-tapping screws
or metric bolts as appropriate for the model you are using.
2.
Use silicone sealant to seal all five countersunk fasteners in a
watertight manner in order to prevent water ingress into the
bottom unit.
3.
Use a utility knife to score the membrane at both locations.
