I − UNIT INFORMATION
All major components (indoor blower and coil) must be
matched according to Lennox recommendations for the
compressor to be covered under warranty. Refer to the En-
gineering Handbook for approved system matchups. A
misapplied system will cause erratic operation and can re-
sult in early compressor failure.
CAUTION
To prevent personal injury, or damage to panels, unit
or structure, be sure to observe the following:
While installing or servicing this unit, carefully stow
all removed panels out of the way, so that the panels
will not cause injury to personnel, nor cause damage
to objects or structures nearby, nor will the panels be
subjected to damage (e.g., being bent or scratched).
While handling or stowing the panels, consider any
weather conditions, especially windy conditions,
that may cause panels to be blown around and bat-
tered.

1. Remove 2 screws, allowing the panel to swing open
slightly (see figure 1).
2. Hold the panel firmly throughout this procedure.
