Application
Considerations
Low Ambient Cooling
As manufactured, these units can
operate to 50° F (10°C) in the cooling
mode of operation. An accessory head
pressure control will allow operation to
0° F (-17.8°C) outdoor ambient. When
using these units with control systems
such as bypass changeover Variable Air
Volume, make sure you consider the
requirement for a head pressure control
to allow low ambient cooling.
Application of this product should be
within the catalogued airflow and
performance considerations.
Clearance Requirements
The recommended clearances identified
with unit dimensions should be
maintained to assure adequate
serviceability, maximum capacity and
peak operating efficiency. Actual
clearances which appear inadequate
should be reviewed with the local Trane
Representative.
180° Blower Rotation
The TWE050, 075, and 100 air handler
blower section can be rotated 180° to
change the discharge pattern. This
modification must be done in the field
and requires an addition of kit. See unit
installer's guide.
