Fig. 1 -- Slope Coil Unit in Upflow Application
Step 2—Mount Unit
Unit can stand or lie on floor, or hang from ceiling or wall. Allow
space for wiring, piping, and servicing unit.
IMPORTANT
: When unit is installed over a finished ceiling
and/or living area, building codes may require a field--supplied
secondary condensate pan to be installed under the entire unit.
Some localities may allow as an alternative, the running of a
separate, secondary condensate line. Consult local codes for
additional restrictions or precautions.
A. Upflow Installation
If return air is to be ducted through a floor, set unit on floor over
opening and use 1/8-- to 1/4--in. thick fireproof resilient gasket
between duct, unit, and floor.
Side return is a field option on slope coil models. Cut opening per
dimensions. (See Fig. 1.) A field--supplied bottom closure is
required.
B. 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. thick, between duct,
unit, and floor.
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. 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.
UNIT OR PROPERTY DAMAGE HAZARD
Failure to follow this 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 units. The vertical drains have an overflow hole
between the primary and secondary drain holes. This hole is
plugged for all applications except downflow, but must be
used for downflow. During the conversion process, remove
the plastic cap covering the vertical drains only and discard.
Remove the plug from the overflow hole and discard. At
completion of the downflow installation, caulk around the
vertical pan fitting to door joint to retain the low air leak
performance of the unit.
CAUTION
!
C. Horizontal Installation
Units must not be installed with access panels facing up or down.
All other units are factory built for horizontal left installation.
(See Fig. 2 and 3.) When suspending unit from ceiling, dimples
in casing indicate suitable location of screws for mounting metal
support straps. (See 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.
