Procedure
1. If the minimum depth subbase is required, discard the
side extension pieces.
2. If more than the minimum depth is required, determine
the depth of the side extension pieces desired and break
at the proper score line. Insert the extension pieces into
the front assembly and secure with two short black
screws at each side.
3. Insert leveling bolts into subbase bottom ange. Four (4)
bolts are required if side extensions are used. Only two
(2) bolts are required if side extensions are not used.
4. Place the subbase on the oor and align its center line
with the center line of the wall opening. Do not fasten the
subbase to the oor. Attach the subbase to the wall sleeve
using the clips provided with the subbase.
5. The wiring should be roughed in and the conduit
connected to the subbase junction box. Complete the
installation by wiring the receptacle to the incoming
power supply.
