. Avoid locations where the air dryer will be in direct contact with wind and rain. (Places where relative humidity is greater than 85%) . Avoid exposure to direct sunlight. . Avoid locations that contain much dust, corrosive gases, or flammable gases. Failure due to corrosion is not covered under warranty. However, when the risk of corrosion is high, select “Option C” (copper tubing with anti-corrosive treatment). . Avoid locations of poor ventilation and high temperature. . Avoid too close to a wall etc. Leave sufficient room between the dryer and the wall according to the “Maintenance space” in the operation manual. . Avoid locations where a dryer could draw in high temperature air that is discharged from an air compressor or other dryer. . Avoid locations subjected to vibration. . Avoid possible locations where the drain can freeze. . Use the air dryer with an ambient temperature lower than 40°C. . Avoid installation on machines for transporting, such as trucks, ships, etc. Installation Caution The air exhaust should not flow into the neighboring equipment. (Top side) . Be careful to avoid an error in connecting the air piping at the compressed air inlet (IN) and outlet (OUT). . Install by-pass piping since it is needed for maintenance. Air Piping Caution . A polyurethane tube is attached as a drain tube for the IDFA3E to 75E and IDFA100F to 150F. Use this tube to discharge drainage. . Do not use the drain tube in an upward direction. Do not bend or crush the drain tube. (Operation of the auto drain will stop water vapor from discharging through the air outlet.) If it is unavoidable that the tube goes upwards, make sure it only goes as far as the position of the auto drain. Drain Tube Caution . Connect the power supply to the terminal block. . Install a suitable circuit breaker applicable for the specific model. . The voltage fluctuation should be maintained within ±10% of the rated voltage. Note) Select a circuit breaker with a sensitivity current 30 mA. As regards rated current, refer to “Applicable circuit breaker capacity” on pages 73, 76 and 79.
