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.
CAUTION
!
NOTE
: Modular units can be disassembled and components
moved separately to installation area for reassembly. This process
accommodates small scuttle holes and limiting entrances to
installation sites. (See Fig. 4.)

Horizontal Right Conversion of Units With Slope Coils
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. 5.)
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. 5.)
5. Attach coil to casing flange using coil mounting screw pre-
viously removed.
6. Make sure the pan cap in the fitting door is properly seated
on the fitting door to retain the low air leak rating of the
unit.
7. Add gaskets from kit KFAHD per kit instructions.
8. Align holes with tubing connections and condensate pan
connections, and reinstall access panels and fitting panel.
