TRANE
The unit should be installed for
horizontal application only. Suspend the
unit using the factory-provided threaded
mounting holes on top of the unit. This
is usually accomplished through the
use of spring or rubber isolators, which
are to be furnished by the installer.
All units must be mounted level to
assure
proper
drainage
operation.
Check that the supporting structure
is strong enought to support unit
weights.
Align the mounting holes with structural
support and secure suspension rods
to the structure, then to the air handler
cabinet. If the mounting holes locations
do not permit proper alignment with
existing structure. It may be necessary
to field fabricate cross members on
existing structural beams.
(c) Coil Piping Connections.
Coils are fitted with 1-1/4" (32mm)
BSPT MALE threaded connections. To
complete piping connections, attach the
water piping with 1-1/4 inch connection
to the coil. The water inlet is on the
bottom and water outlet on the top of
the coil. Coil connection size and coil
connection locations are given in page
3.
(d)
Condensate
Connections.
These air handlers come standard with
a drain pan. Drain connections are
provided on one side of the air
handlers.
For a typical drain trap assembly, see

different design than the negative
pressure trap. Refer to Figure and the
