TRE

Extruded Relief or Intake Ventilator

INSTALLATION, OPERATION AND MAINTENANCE MANUAL

Receiving and Inspection

Immediately upon receipt of an TRE unit, carefully in-

spect it for damage and shortage.

• Check dampers (if supplied) for free operation of all

moving parts.

• Record on the Delivery Receipt any visible sign of

damage.

Handling

Lift the unit by the base. Never lift by the tiers.

Storage

If the fan is stored for any length of time prior to installa-

tion, store it in its original shipping crate and protect it from

dust, debris and the weather.

TRE

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 ofcial 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 specic 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 lters 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 lter.

Under most conditions lters 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 lter. 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 lter in a

“back-wash” ow (note airow arrow on the lter frame).

Once the lter is dry, it may be returned to the appropri-

ate lter racks in the same orientation (airow direction) as

they were removed.

Maintenance

Establish a denite schedule per the manufacturers rec-

ommendation for inspecting any accessory lters or damp-

er units that may have been installed with the ventilator.

Inspect the ventilator yearly for any debris that may ob-

struct airow. 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

lters. 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.
