Instructions for repositioning baffles to reverse
airflow direction
1) Remove Screws "A".
2) Lift each baffle slightly and slide forward removing each
individual baffle completely from the heat exchanger.
3) Remove the top baffle support. Re-use screws "B" and
install the top baffle support on the opposite end of the
heat exchanger.
4) Re-install the bottom baffle support and brackets on the
opposite end of the heat exchanger.
5) Reverse Steps 1 and 2 -- re-installing all of the baffles.
