Filters

Bag and cartridge filter sections can be used as a pre-filter
section, a final filter section, or both. This use is
determined by the filter's placement in relation to the fan.
• A final filter is placed after the fan.
• A pre-filter 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 heating and
cooling coils.

Final Filter Section

A final filter section 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.

Pre-Filter Section

Tiedown
A pre-filter section has no special installation
requirements unless placed directly upstream of a plenum
fan. In these configurations, ensure a blank section is
placed between the fan inlet and the filter section.
Trane recommends the use of disposable pre-filters with
high-efficiency filters. Disposable pre-filters slide into the
mounting tracks just ahead of the bag/cartridge filters.

Filter Installation

Hazardous Voltage!
Failure to disconnect power before servicing could
result in death or serious injury. Disconnect all electric
power, including remote disconnects before servicing.
Follow proper lockout/tagout procedures to ensure the
power can not be inadvertently energized.
Required
To install filters:
clearance
1. Disconnect the power to the unit.
2. Open the filter section access door.
3. Slide the filters into the tracks.
Note: Bag filters must be installed with the pleats in the
vertical plane.
4. The block-off is permanently installed and will create a
seal when the access door is closed.
