INSTALLATION INSTRUCTIONS
C. DOWNFLOW INSTALLATION
CAUTION
!
PRODUCT 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−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.
Failure to follow instructions could result in personal injury
or product and property damage.
WARNING
!
STRUCTURAL DAMAGE
Failure to follow this warning could result in personal
injury or death, or property damage.
Combustible floor base is required when installing in a
downflow application with electric heat strips.
Structural damage could
downflow base accessory kit is not use when installing in
a downflow application.
In this application, field conversion of the evaporator coil is
required using accessory Downflow Kit along with an

accessory Base Kit. Set unit on floor over opening and use
1/8" to 1/4" thick fireproof resilient gasket between duct, unit,
and floor. Refer to installation instructions packaged with
accessory kit. See Product Specification literature for kit part
numbers.
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 low air leak
performance of the unit.
NOTE: Gasket kit number (EBAC01GSK) is also required for
all downflow applications to maintain low air leak/low sweat
performance.
D. HORIZONTAL INSTALLATION
Unit must NOT be installed with access panels facing up or
down. Access panels must only face to the side.
All models are factory built for horizontal left installation (refer
to Figure 3 and Figure 4). They can be field converted to
horizontal right (accessory Gasket Kit required, see Product
Specification literature for part number). Refer to Figure 5
and Figure 6.
NOTE: When suspending unit from ceiling, dimples in casing
indicate suitable location of screws for mounting metal
support straps (refer to Figure 3).
NOTE: For optimum condensate drainage performance in
horizontal installations, unit should be leveled along its length
and width.
