When the air dryer is operated under the following stated conditions, a protection circuit is activated, the light turns off and operation stops. . When the compressed air temperature is too high. . When the compressed air flow rate is too high. . When the ambient temperature is too high. (40°C or higher, however, 45°C or higher for IDFA100F to 150F) . When the fluctuation of the power supply is beyond the rated voltage ±10%. . When the dryer is drawing in high temperature air that is discharged from an air compressor or other dryer. . The ventilation port is obstructed by a wall or clogged with dust. Protection Circuit Caution Since the auto drain of the IDFA3E to 75E is designed in such a way that the valve remains open unless the air pressure rises to 0.15 MPa or higher (0.05 MPa or more for IDFA100F to 150F), air will blow out from the drain discharge port at the time of air compressor start-up until the pressure increases. Therefore, if an air compressor has a small air delivery, the pressure may not be sufficient. Compressor Air Delivery Caution The auto drain may not function properly, depending on the quality of the compressed air. Check the operation once a day. Auto Drain Caution Remove dust from the ventilation area once a month using a vacuum cleaner or an air blow nozzle. Cleaning of Ventilation Area Caution Allow at least three minutes before restarting the dryer. If the air dryer is restarted within three minutes after being stopped, the protection circuit will be activated, operating light turns off and the dryer will not be activated. Time Delay for Restarting Caution Do not modify the standard product using any of the optional specifications once the product has been supplied to a customer. Check the specifications carefully before selecting an air dryer. Modifying the Standard Specifications Caution Use an air compressor with an air delivery of 100 L/min or larger with the IDFA3E to 75E series. Air Piping Caution . When tightening piping at the air inlet/outlet tube, the hexagonal parts of the port on the air dryer side or piping should be held firmly with a spanner or adjustable angle wrench. . Variations in operating conditions may cause condensation to form at the surface of the outlet piping. Apply thermal insulation around the piping to prevent condensation from forming. . Vibration resulting from the compressor should not be transmitted through air piping to the air dryer. . Do not allow the weight of the piping to lie directly on the air dryer.
