FZ4ANP: Installation Instructions
DOWNFLOW INSTALLATION
In this application, field conversion of the evaporator is required using
accessory downflow kit along with an accessory base kit. Use fireproof
resilient gasket, 1/8 to 1/4-in (3 to 6 mm) thick, between duct, unit, and
floor.
CAUTION
!
PRODUCT OR PROPERTY DAMAGE HAZARD
Failure to follow this warning caution may result in product or property
damage.
The conversion of the fan coil to downflow requires special procedures
for the condensate drains on both A-coil and Slope-coil units. The
vertical drains have an overflow hole between the primary and
secondary drain holes. This hole is plugged for all applications except
downflow, and must be used for downflow. During conversion process,
remove plastic cap covering vertical drains only and discard. Remove
plug from overflow hole and discard. At completion of downflow
installation, caulk around vertical pan fitting to door joint to retain low
air leak performance of the unit.
Manufacturer reserves the right to change, at any time, specifications and designs without notice and without obligations.

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.
3). When suspending unit from ceiling, dimples in casing indicate
suitable location of screws for mounting metal support straps
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.
