Installation and operation
using an anemometer.
Do not connect cool air inlet ducts directly to the
compressor inlet side.
To eliminate transmission of vibrations, provide a soft
bellows connector between the duct and the compressor.
Contact ELGi in case you need to provide a duct
connection or filter fitment on the compressor.
