Siting Considerations
All the units are air cooled, air being pulled in through the front and
expelled from the rear. The ventilation grilles should never be
obstructed, therefore, as this will detract from the performance.
Also the fridge units should never be situated in an enclosed space
or near an extractor fan, this too will detract from the performance.
