General information
Reznor destratification fans are a self
contained unit incorporating adjustable four
way louvre discharge, a high efficiency axial
fan and an integral pre-wired thermostat
mounted on the side of the unit.
Care should be taken to ensure that the
unit is not sited in areas where it would be
undesirable to recirculate high level air because
of fumes, etc., or where corrosive atmospheres
may attack the fan unit.
To obtain maximum benefit, destratification
fans should be sited in the higher part of the
building, close to the apex, approximately one
metre below the peak.
Fans located over heat generating machinery
or lighting maximise the benefits of 'free heat'
whilst fans positioned close to doorways help
to quickly restore comfortable conditions after
door operation.
Fans should not be sited adjacent to large
expanses of wall or roof glazing, or in
close proximity to open flued heater units,
as the airflow could adversely affect flue
performance.
The destratification fan is equipped with four
eyebolt suspension points, one on each corner,
and may be suspended from these using
chains or wires.
Each destratification fan is equipped with a
cable gland mains input positioned on the
terminal box on top of the main fan.
Each unit will require a 230V 50Hz 1ph fused
supply to operate.
For safety and maintenance purposes, each
fan should be fitted with an isolator located
adjacent to the unit.
