Product Operation
Free Cooling Mode
The temperature sensor for the unit shall measure the exhaust air temperature of the cabin at the opposite cabin wall to
the unit. The unit shall vary the fan speed to increase/decrease the air volume to maintain a constant room temperature
set point. When the temperature of the cabin reaches a minimum set point, the unit shall stop the fan and close the
exhaust damper, to avoid over cooling the cabin space.
Free Cooling Mode
The exhaust damper shall be either pressure regulated or mechanically actuated.

Positioning
The unit must be positioned at least 600mm from the ground to supply the cabin space with cool air at a lower
point and allow the warm air rise to up to a higher exhaust on the opposite side of the cabin. This should allow even air
distribution and maximise performance of the unit’s application.
There must be a minimum of 3 metres between the unit and the exhaust damper.
