Outlet Box Mounting (Fig. 4)
Use a horizontally mounted outlet box if possible. If a
vertical outlet box is used, the subbase must be mounted on
a 202689A Cover Plate Assembly (ordered separately).
Follow the instructions provided with the cover plate as-
sembly.
Align the subbase mounting holes on the outlet box and
loosely fasten with the two screws.
Carefully level the subbase (Fig. 3) and firmly tighten
the screws.
