The unit as shipped from the factory is not confi gured for vertical down or horizontal right
discharge applications and must be converted in the fi eld to work in those applications.

3. 4. Reversing the heat exchanger

DRIP LOOP NOTE: When installing the unit in down or horizontal right discharge
applications, make sure the wires going to the blower motor form a proper drip loop to
force any condensate that might form on the wires to drip off the lowest point of the wiring
instead of entering the motor or motor control. This may require cutting the wire-tie and
installing a new wire-tie to form a new drip loop.
Reverse the heat exchanger by the procedure below.
(1) Remove the screws fi xing three sheet metals.
Then remove the sheet metals.
(2) From here, the work is diff erent depending on the 24/30 models or 36/48 models. The
