flanges. The installer may
with 914mm

However,
the
914
mm

AE
recommends
that
only one
side,
right or

have the full
914
mm
(36")
clearance while the
other
side
must have 152 mm
(6").
The
above
figure
shows
152
mm

on
the left with
914
mm
(36") on the
right side. This
allows access
to the
magnetics
section for retorquing bolts
and
the1mal
scan
of
connections. This
is
not a
code
setback
requirement
and
152 mm
(6") on each side
is
an acceptable installation
practice.
