IMPORTANT: READ PRIOR TO STARTING THIS EQUIPMENT 1.0 INSTALLATION 1.1 Location For typical placement in a compressed air system, see drawing. B. Air compressor intake – Locate air compressor so that Aftercooler Dryer contaminants potentially harmful to the dryer (e.g. ammo- nia) are not drawn into the air system. Compressor Oil Removal Separator C. Free Air Flow - Allow a minimum of 36 inches (914 mm) Filter clearance for free air flow. Service - To facilitate maintenance leave 36 inches (914 mm) of clearance in front of dryer. D. Standard units are designed to operate in ambients: Air-cooled: 40 to 110°F (4 to 43°C). - Page 4 1.2 Mounting B.
