Vertical mounting
When mounted vertically, the air handler's primary
drain connection is located in the center of the unit.
The slightly higher drain to the left is the secondary
drain.
Attach the drain connector and tighten TO THE
PROPER TORQUE SHOWN PREVIOUSLY with
sealant and install the drain line.
IMPORTANT
Over-tightening the drain connection could
result in drain pan breakage and failure.
The secondary connection should be connected
to a separate drainage system. Run the secon-
dary drain so the occupants will be able to notice
water flowing through the secondary drain indi-
cating a blockage in the primary drain. Optional
use for the secondary is a primary drain line over-
flow switch (provided by others). This device will
shut the cooling operation unit down in the event
of a primary drain line blockage. See wiring sec-
tion for connecting this device.
CAUTION
If secondary drain is not installed, the secondary access must be plugged.
13. Electrical wiring
WARNING
Electrical work should be done by a qualified
electrical contractor in accordance with "Engi-
neering Standards for Electrical Installation" and
supplied installation manuals. If the power circuit
lacks capacity or has an installation failure, it may
cause a risk of electrical shock or fire.
• Be sure to follow local and national code re-
quirements when wiring these units.
Specifications are subject to change without notice.

Horizontal (Left or Right):
If the unit is installed horizontally, remove the
knockout in the front panel to gain access to
the side drain pan connections. Attach the con-
nector as described above and route drain line.
Any vertical drain pan openings must be cov-
ered to eliminate air loss which will decrease
the capacity of the unit.
Over-tightening the drain connection
could result in drain pan breakage and
failure.
The secondary connection should be con-
nected to a separate drainage system. Run
the secondary drain so the occupants will be
able to notice water flowing through the sec-
ondary drain indicating a blockage in the pri-
mary drain. Optional use for the secondary
is a primary drain line overflow switch (pro-
vided by others). This device will shut the
cooling operation unit down in the event of a
primary drain line blockage. See wiring sec-
tion for connecting this device.
• Install the unit in a manner to prevent that any
of the control circuit cables (remote controller,
transmission cables) are brought in direct con-
tact with the power cable outside the unit.
• Ensure that there is no tension on any wire
connections.
• Some cables (power, remote controller or
transmission) above the ceiling may become
damaged by accident or by animals. Use con-
duit as much as possible to prevent damage.
• Never connect the power cable to leads for the
transmission cables. The cables will break.
