. Avoid locations where the air dryer will be in direct contact with wind and rain. (Avoid locations where relative humidity is 85% or more.) . 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 the option C (anti-corrosive treatment for copper tube). . Avoid locations of poor ventilation and high temperature. . Avoid locations where the air dryer is too close to a wall, etc. Leave a sufficient space between the air dryer and the wall according to the “Maintenance Space” in the operation manual. . Avoid locations where the air dryer could draw in high temperature air discharged from an air compressor or other dryer. . Avoid locations subjected to vibration. . Avoid possible locations where the drain can freeze. . Avoid locations with an ambient temperature 40°C or higher (IDF100F to 150F: 45.. or higher). . Avoid installation on machines for transporting, such as vehicles, ships, etc. Installation Caution . A polyurethane tube is attached as a drain tube for the IDF1E to 150F, IDU3E to 75E. Use this tube to discharge drainage to a drain tank, etc. . 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 Check that the exhaust air does not flow into the neighboring equipment. <100 VAC> . Insert the power supply plug to an exclusive 100 VAC power outlet. . Install a circuit breaker Note 1) suitable to each model for the power supply. . Maintain voltage fluctuation within ±10% of the rated voltage. . Be sure to ground the power supply prior to use. . Multiple-branch wiring is dangerous since it causes overheating. . Do not extend the power cable by using a table tap, etc. A voltage drop may cause the air dryer to stop operating. Note 1) Select a circuit breaker with a sensitivity current 30 mA and a rated current 10 A. <200 VAC> . Connect the power supply to the terminal block. . Install a circuit breaker Note 2) suitable to each model for the power supply. . Maintain voltage fluctuation within ±10% of the rated voltage. Note 2) Select a circuit breaker with a sensitivity current 30 mA. As regards rated current, refer to “Applicable circuit breaker capacity” on pages 29, 33, 36, 37, 41, 44 and 47. Power Supply Caution When the voltage used is different than specified for a standard product, use a separately installed power transformer.
