Component Installation Requirements
Each component in the T-Series air handler may have installation requirements that could
affect the unit’s performance.
Note: For components included in the unit but not included in this manual, reference the
component manufacturers specific Installation, Maintenance, and Operation
manual. Copies of these manuals are either included in the package with this unit
or are attached to the components mounted in the unit.
Diffuser
Diffusers are usually placed between a fan and a downstream coil or filter. Because
placement is critical to unit performance, verify the correct placement of the diffuser
before assembling the section (see
Figure 19
and
Figure 20
).
Filters
Bag and cartridge filter sections can be used as a pre-filter section, a final filter section,
or both. This determined by the filter’s placement in relation to the fan:
•
A final filter section is placed after the fan.
•
A pre-filter section is placed before the fan.
Note: Cartridge and bag filters provided by Trane are fitted with a 7/8-inch header that fits
in the filter track. If using filters supplied by another manufacturer, filters should
be purchased with a 7/8-inch header. In some cases it may be necessary to gasket
other manufacturers’ filters to ensure a good air seal.
Filters should be installed when the unit is set. This will protect internal components,
such as the unit’s heating and cooling coils.
Final Filter Section
A final filter should not be bolted directly to the face of a fan section. One or more
intermediate sections must be placed between the fan discharge and the filter section.
