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 panels and fitting panel ( Fig. 5 ).
2. Remove coil mounting screw securing coil assembly to right side
casing flange.
3. Remove coil assembly.
4. Lay fan coil on its right side and reinstall coil assembly with
condensate pan down ( Fig. 4 ).
5. Attach coil to casing flange using previously removed coil
mounting screw.
6. Make sure pan cap in fitting door is properly seated on fitting door
to retain low air leak rating of the unit.
7. Add gaskets from kit - KFAHD.
8. Align holes with tubing connections and condensate pan
connections. Reinstall access panels and fitting panel.
9. Make sure liquid and suction tube grommets are in place to prevent
air leaks and cabinet sweating. Install grommets after brazing.
Horizontal Right Conversion of Units with A-Coils
1. Remove blower and coil access panels ( Fig. 5 ).
2. Remove metal clip securing fitting panel to condensate pan.
Remove fitting panel.
3. Remove 2 snap-in clips securing A-coil in unit.
4. Slide coil and pan assembly out of unit.
5. Remove horizontal drain pan support bracket from coil support rail
on left side of unit and reinstall on coil support rail on right side of
unit (Fig. 6).
6. Convert air seal assembly for horizontal right.
a. Remove air seal assembly from coil by removing 4 screws
( Fig. 5 ).
b. Remove air splitter (B) from coil seal assembly by removing 3
screws ( Fig. 5 inset).
c. Remove filler plate (A) and install air splitter (B) in place of filler
plate.
