INSTALLATION Location Locate your Pioneer PHL series dryer on a level floor free from vibrations and in clean surroundings. Although the dryer is a freestanding package, it may be secured by bolting the dryer base to the floor. Allow approximately three feet on each side of the dryer for ease of connecting and maintaining the dryer. - Page 4 Filtration All regenerative desiccant dryers are designed to remove water in the vapor phase. The possibility of liquid carry over to the desiccant dryer must be avoided. A coalescing pre-filter will eliminate the carry over of droplets and aerosol-sized mists of both liquid water and compressor lubricant. The use of a Pioneer coalescing filter (CS Series) will enhance the dew point depression capability of the dryer.
