For ease in installation, it is best to make any necessary
coil configuration changes before setting air handler in
place.
Refrigerant Metering Device
BCE5C
units are equipped with a factory-installed check/
expansion valve or an RFC device.
Upflow Application
1. The air handler must be supported on the bottom only
and set on solid floor or field-supplied support frame.
Securely attach the air handler to the floor or support
frame.

2.
If installing a unit in an upflow application, remove the
horizontal drain pan.
NOTE:
The horizontal drain pan is not required in
upflow air discharge installations; its removal provides
the best efficiency and air flow.
3.
Place the unit in the desired location and slope unit.
Connect return and supply air plenums as required
using sheet metal screws.
4. Install units that have no return air plenum on a stand
that is at least 14” from the floor. This will allow proper
air return.
Horizontal Applications
When removing the coil, there is a possibility of danger
of equipment damage and personal injury. Be careful
when removing the coil assembly from a unit installed
in right- or left-hand applications. The coil may tip into
the drain pan once it is clear of the cabinet. Support the
coil when removing it.
IMPORTANT
NOTE:
When the unit is installed in horizontal applications,
a secondary drain pan is recommended. Refer to local
codes.
NOTE:
This unit may be installed in left-hand or right-hand
air discharge horizontal applications. Adequate support
must be provided to ensure cabinet integrity. Ensure that
there is adequate room to remove service and access
panels if installing in the horizontal position.
Right-Hand Discharge
1.
Determine which plugs are required for drain line
connections.
2.
With access door removed, remove drain line plugs to
install drain lines.
3.
Set unit so that it is sloped toward the upflow drain pan
end of the unit and level from front to back of unit (see

If the unit is suspended, the entire length of the cabinet
must be supported. If you use a chain or strap, use a
piece of angle iron or sheet metal attached to the unit
(either above or below) to support the length of the
cabinet. Use securing screws no longer than 1/2 inch
to avoid damaging the coil or filter. See Figure 3. Use
sheet metal screws to connect the return and supply
air plenums as required.
