4.2.4 SETTING UP THE DUCT FOR OUTDOOR AIR INTAKE
For optimal operation of the Free Cooling plenum, the outdoor air damper will have to be connected to the outside of the
building so that it can draw in outdoor air:
The installer will set up the connection duct and outdoor air intake. It is advisable to provide:
An external opening with slots or grilles to prevent rainfall, harmful animals and human entry.
An outdoor air ltration system, with G4 eciency level.
A vibration damping joint, connected to the plenum, to prevent the propagation of any vibrations from operation of the
unit.
4.2.5 INSTALLATION OF FREE COOLING PLENUM TEMPERATURE PROBES
For optimal operation of the Free Cooling plenum, it will be necessary to position the outdoor air and return air temperature
probes, both supplied as standard:
The outdoor air temperature probe, to be installed on the duct, must be positioned in the outdoor air intake duct so that it
can detect the outdoor air temperature.
The return air temperature probe, to be installed on the wall, must be positioned so that it can detect the controlled room
temperature.
