Modular Units
Modular units (3½, 4, and 5 ton) can be disassembled and components
moved separately to the installation area for reassembly. This process
accommodates small scuttle holes and limiting entrances to installation
sites (Fig. 2).
To disassemble the unit, disconnect the 4-pin sensor wire harness at the
dissipation board and undo the wire routing in the cabinet. Remove the
rear corner brackets by removing 2 screws which secure the brackets.
Remove either 2 screws in each front corner of the coil box, or 2 screws
in the blower box. Do not remove all 4 screws in each corner. Sections
may now be separated by lifting the top section from the lower section.
To reassemble, reverse above procedure. Be certain to reinstall all
fasteners when reassembling.
Manufactured and Mobile Home Housing Applications
1. Secure the fan coil to the structure using field-supplied hardware.
2. Allow a minimum of 24" (610 mm) clearance from access panels.
3. Recommended method of securing for typical applications:
a. If fan coil is away from wall, attach pipe strap to top of fan coil
using no. 10 self-tapping screws. Angle strap down and away
from back of fan coil, remove all slack, and fasten to wall stud of
structure using 5/16" lag screws. Typical both sides of fan coil.
b. If fan coil is against wall, secure fan coil to wall stud using 1/8"
(3 mm) thick right-angle brackets. Attach brackets to fan coil
using no. 10 self-tapping screws and to wall stud using 5/16" lag
screws (Fig. 2).

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 ¼" (3 to 6 mm) thick, between duct, unit, and
floor.
NOTE: To convert units for downflow applications, refer to Installation
Instructions supplied with kit for proper installation. See the Product
Data or contact your supplier for the kit number. Use fireproof resilient
gasket, 1/8" to ¼" (3 to 6 mm) thick, between duct, unit, and floor.
NOTE: A gasket kit is also required for all downflow applications to
maintain low air leak/low sweat performance. See the Product Data or
contact your supplier for the kit number.
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. 4 and
Fig. 5). When suspending unit from ceiling, dimples in casing indicate
suitable location of screws for mounting metal support straps (Fig. 4).
For horizontal applications having high return static and humid return
air, the Water Management Kit may need to be used to assist in water
management. See the Product Data or contact your supplier for the kit
number.
NOTE: Modular units 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. 2).

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.
CAUTION
!
PROPERTY DAMAGE HAZARD
Failure to follow this caution may result in product or property damage.
For optimum condensate drainage performance in horizontal
installations, unit should be leveled along its length and width.
