Fig. 5 – Conversion for Horizontal Right Applications - A-Coil
NOTE: To convert units for downflow applications, refer to Installation
Instructions supplied with kit for proper installation. For slope fan coils,
use kit Part No. KFADC0201SLP. For A-coils, use kit Part No.
KFADC0401ACL. Use fireproof resilient gasket, 1/8 to 1/4-in (3 to 6
mm) thick, between duct, unit, and floor.
NOTE: Gasket kit number KFAHD0101SLP is also required for all
downflow applications to maintain low air leak/low sweat performance.
HORIZONTAL INSTALLATION
Units must not be installed with access panels facing up or down. All
other units are factory built for horizontal left installation. (Fig. 2 and
Fig. 3.) When suspending unit from ceiling, dimples in casing indicate
suitable location of screws for mounting metal support straps. (Fig. 2)
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: Modular units (sizes 060 and 061) can be disassembled and
components moved separately to installation area for reassembly. This
process accommodates small scuttle holes and limiting entrances to
installation sites. (Fig. 6)
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.
