CAUTION
!
PROPERTY DAMAGE HAZARD
Failure to follow this caution may result in product or property
damage.
For optimum condensate drainage performance in horizontal
installations, unit should be leveled along its length and width.
For horizontal applications having high return static and humid
return air, the Water Management Kit, KFAHC0125AAA, may
need to be used to assist in water management.

NOTE: Gasket kit number KFAHD0101SLP is required for
horizontal slope coil conversion to maintain low air leak/low sweat
performance.
1. Remove blower and coil access panel and fitting panel. (See
Fig. 4.)
2. Remove coil mounting screw securing coil assembly to
right side casing flange.
3. Remove coil assembly.
4. Lay fan coil unit on its right side and reinstall coil assembly
with condensate pan down. (See Fig. 4.)
5. Attach coil to casing flange using coil mounting screw pre-
viously removed.
