A:
EMI air handlers are manufactured with a
low-voltage transformer installed. When
connecting an EMI air handler to a non-
EMI condenser, check to ensure that
there is no 24v control transformer in
the outdoor unit. Only one transformer
is required. If both the indoor unit and
outdoor unit contain a transformer, one
must be removed from the system.
