The instrument requires clean, dry, non-corrosive air for cooling purposes. This is supplied to the instrument through an air supply vent located at the top of the instrument (beside the chimney). The vent is fitted with a dust filter to screen out particulate matter from the surrounding environment. This filter should be kept clean to prevent reduced air flow.
