FEM4X, FEM4P, REM4X, REM4P: Installation Instructions
DOWNFLOW INSTALLATION
WARNING
!
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 HAZARD
Failure to follow this warning could result in personal injury, death, /or
property damage.
Combustible floor base is required when installing in a downflow
application with electric heat strips.
Structural damage could occur if manufacturer's 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.
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
Fig.
4). They can be field converted to horizontal right (accessory
Gasket Kit required, see Product Specification literature for part
number). Refer to
Fig. 5
and
NOTE: When suspending unit from ceiling, dimples in casing indicate
suitable location of screws for mounting metal support straps
NOTE: For optimum condensate drainage performance in horizontal
installations, unit should be leveled along its length and width.
Horizontal Right Conversion of Units with Slope Coils
1. Remove blower and coil access panel and fitting panel
2. Remove coil mounting screw securing coil assembly to right side
casing flange.
3. Remove coil assembly.
4. Lay fan coil unit on its right side and reinstall coil assembly with
condensate pan down.
5. Attach coil to casing flange using coil mounting screw previously
removed.
6. Align holes with tubing connections and condensate pan
connections, and reinstall access panels and fitting panel. After
brazing, make sure liquid and suction tube grommets are in place to
prevent air leaks and cabinet sweating.
