Removal of the blower assembly in this style of air-handler is not as straightforward as
with more conventional residential air-handlers due to its compact design. Therefore,
Sections 7.5.1 – 7.5.3 are provided to aid the technician in that process.
the blower assembly on the larger cabinet requires a partial disassembly of the cabi-
net, so the procedure in Section 7.5.3 may be preferable if only the motor needs to be
removed for servicing or replacement.
