INSTALLATION, OPERATION AND MAINTENANCE MANUAL
The attachment of roof mounted fans to the roof curb as
well as the attachment of roof curbs to the building struc-
ture must exceed the structural requirements based on the
environmental loading derived from the applicable building
code for the site. The local code official may require varia-
tions from the recognized code based on local data. The
licensed engineer of record will be responsible for prescrib-
ing the correct attachment based on construction materials,
code requirements and environmental effects specific to the
installation.
Failure to follow these instructions could result in death or
serious injury.
Installation
Damper and Curb Installation
Curb dimensions are calculated by adding 4" to the
throat width and throat length.
The optional backdraft damper is 1-1/2" larger than the
throat length and throat width. The damper is to be mount-
ed in the throat of the TRE.
Optional filters are shipped installed in the unit from the
factory.
Filters
Filter inspection and cleaning intervals can vary from
once a week to twice per year depending on contaminant
present and acceptable pressure drops across the filter.
Under most conditions filters may be cleaned with hot wa-
ter and a mild soap solution (such as dish washing liquid)
or steam. Some caustic cleaners will damage the filter. If
in doubt, please consult the factory for a compatibility list.
High pressure spray washers should be limited to
2,000psi operating pressure. Every attempt should be
made to remove the contaminants from the filter in a
"back-wash" flow (note airflow arrow on the filter frame).
Once the filter is dry, it may be returned to the appropri-
ate filter racks in the same orientation (airflow direction) as
they were removed.
Maintenance
Establish a definite schedule per the manufacturers rec-
ommendation for inspecting any accessory filters or damp-
er units that may have been installed with the ventilator.
Inspect the ventilator yearly for any debris that may ob-
struct airflow. Check exterior surfaces for dust and grease.
To assure proper operation, remove any dust and grease
from the TRE surfaces.
The TRE top cap may be removed for roof top access
to the throat of the ventilator and access to the optional
filters. Filters may be removed for cleaning and mainte-
nance by sliding them up and out of the unit. Be sure to
reinstall all top cap fasteners upon reassembly.
