Where in each cabin should I install the outlet grilles on a climate control system?
The outlet grilles on any Air Conditioning System should be installed at the highest possible point in the cabin, to allow the best possible cooling effect. This principle is the same on a climate control system. Whilst warm air rises, the blower capacity on an Air Conditioning System is up to three times higher than on a heating system and providing the return air grilles are low down the air flow is sufficient to provide a good heating output, despite having high outlets.
