Installation of Subbase
Electric Subbase
An electrical subbase is optional for all 208V and
230V units. A subbase is required for all 265V units.
The subbase is available in 3" (76mm) or 4" (102mm)
heights. The subbase contains leveling legs for
adjustment of up to 1" (25mm) additional height. All
subbases are factory supplied, field installed options.
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 proper score - line. Insert the
extension pieces into the front assembly and
secure with two short black screws at each side.

Four (4) bolts will be needed if side extensions are
used. Only two (2) bolts are required if side

line with the center line of the wall opening. Do
not fasten the subbase to the floor. 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.
