Models F*FP045,048,060 have a coil baffle and support bracket
factory installed for right hand horizontal application (refer to Figure
3C). For left hand applications the coil support bracket must be
moved to the right side of the coil, and the coil baffle must be
rotated to avoid water blow-off.
To rotate baffle, remove the coil assembly from the unit (remove
front two screws holding the coil support bracket and the two
screws holding the drain pan). Remove four screws in coil baffle
and remove the coil baffle and rotate ends.
Resecure the baffle and reinstall the coil assembly ensuring that
the rear of the drain pan is secured under the back flange of the
unit. Reinstall the coil support bracket on the right side of the coil.
