Modular Unit Assembly; Horizontal-Right Conversion Of Units With Slope Coils; Horizontal Right Conversion Of Units With A-Coil - Carrier FK4C Installation And Start-Up Instructions Manual

CAUTION: For optimum condensate drainage performance in horizontal installations, unit should be leveled along its
length or raised 1/4 in. at the air inlet. The unit should also be pitched forward 1/4 in. to 1/2 in. toward the front condensate
drains.
D. Horizontal-Right Conversion of Units with Slope Coils
To convert units for horizontal right installations:
1. Remove blower and coil access panels and fitting panel. (See Fig. 7.)
2. Remove 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. (See Fig. 7.)
5. Attach coil to casing flange using previously removed coil mounting screw.
6. Reinstall access panels and fitting panel, aligning holes with tubing connections and condensate pan connections.
Make sure liquid and suction tube grommets are in place to prevent air leaks and cabinet sweating. Install grommets after brazing.
E. Horizontal Right Conversion of Units With A-Coil
To convert units for horizontal right installations:
1. Remove blower and coil access panels. (See Fig. 8.)
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.
6. Convert air-seal assembly for horizontal right.
a. Remove air-seal assembly from coil by removing 4 screws.
b. Remove air splitter (B) from coil seal assembly by removing 3 screws. (See Fig. 8—factory-shipped inset.)
c. Remove filler plate (A) and install air splitter (B) in place of filler plate.
d. Install filler plate (A) as shown in horizontal right application.
e. Remove condensate troughs (C) and install on opposite tube sheets.
f. Install hose onto plastic spout.
7. Install horizontal pan on right side of coil assembly.
