Page 5: Read Prior To Starting This Equipment
AIR DRYER INSTRUCTION MANUAL READ PRIOR TO STARTING THIS EQUIPMENT 1. This equipment has been thoroughly checked, packed and inspected before leaving our plant. 2. This equipment is shipped to accommodate a forklift truck. Use a forklift when moving and installing this equipment. Never lift it by hooking on to the air inlet and outlet connections. - Page 6 AIR DRYER INSTRUCTION MANUAL Working Flow Compressed air, saturated with water vapor, enters the dryer and is pre-cooled by the outgoing refrigerated air in an air-to-air heat exchanger (pre-cooler). In the pre-cooler, the warm incoming air is pre- cooled and the outgoing refrigerated air is warmed, this reduces the amount of heat that will have to be removed later by the refrigeration system, providing a more energy efficient dryer.

Page 7: Installation
AIR DRYER INSTRUCTION MANUAL INSTALLATION Mounting 1. A dry, well-ventilated area is the best location for installation of the dryer. It also should be in an area where the ambient temperature will not exceed 100°F (38°C) or fall below 34°F (1°C). - Page 8 AIR DRYER INSTRUCTION MANUAL Typical Piping connection Three-valve bypass line should be installed before the dryer air inlet valve and after the dryer air outlet valve. This valve always permits the continued use of the plant compressed air system during any dryer maintenance or servicing operations.

Page 9: Operation
AIR DRYER INSTRUCTION MANUAL OPERATION Preparation for start-up 1. Be sure that voltage to unit, air inlet pressure, air inlet temperature, air flow is as marked on unit serial number tag. 2. Blow off the compressed air lines for a few minutes to remove welding slag. - Page 10 AIR DRYER INSTRUCTION MANUAL During Operation The current models use R134A refrigerant. Units with refrigeration dew-point gauges (models below 400 CFM), make sure reading is in the yellow and green area. If unit has a PLC (models 400 CFM & above), make sure the display shows 37 F (3 C ).
