unused screw holes. Holes must align with front and
back coil end plates. The top cap has a 45º bend on
one side and a 90º bend on the other. The 90º bend

NOTE: Be very careful when reinstalling the screws
into the coil end plate engaging holes. Misaligned
screws may damage the coil.
8. From the upow position, ip cabinet 90º to the left
and set into place. Replace blower assembly. Secure
coil in place by bending down the tab on the cabinet
support rail as illustrated.
9. Install the horizontal shield (-060 model) on the front
edge of the horizontal drain pan as illustrated in Figure
5.
NOTE: For horizontal applications in high humidity
areas, remove the downow rail closest to the drain
pan. To remove rail, remove screw from rail at back
of unit and at cabinet support rail. Remove downow
rail then replace screws. Also, seal around the exiting
drain pipe, liquid and suction lines to prevent inltration
of humid air.
10. Knock out drain seal plate from access door. Secure
plate to cabinet front ange with screw provided.
11. Flip access door and replace it on the unit.
12. Set unit so that it is sloped 1/4ʺ toward the drain pan
end of the unit. Connect return and supply air plenums
as required using sheet metal screws.
13. If suspending the unit, it must be supported along the
entire length of the cabinet. If using chain or strap,
use a piece of angle iron or sheet metal attached to
the unit (either above or below) so that the full length
of the cabinet is supported. Use securing screws no
longer than 1/2ʺ to avoid damage to coil or lter, as
illustrated in Figure 3. Connect return and supply air
plenums as required using sheet metal screws.
Downow Application
NOTE: If downow application is required, separately
order kit number 83M57 and install per kit’s instructions.
Also use metal or class I supply and return air plenums.
Use the installation instruction provided with the downow
kit.
If electric heat section with circuit breakers (ECBA25) is
installed in a BE5C unit in a downow application, the
circuit breakers must be rotated 180° to the UP position.
See ECBA25 installation instructions for more details.
