APPENDIX J:
Schematics, Assembly Drawings,
and Parts List
The
documents
in
this
Appendix
reflect
the
actual
construction
of
your
unit
as
accurately
as possible. If changes are made, they will
be
found
in an Addendum
inserted
in
the
front
of
this
Manual.
If
there
is
a disagreement
between
these
drawings and your
actual
unit,
it
more likely reflects an error
in
documentation
than an error in the construction of your unit.
If
you
intend
to
replace
parts,
please
consult
the
section
in
Appendix
F on
Selecting And Ordering Replacement Parts.
