Use the air dryer with an ambient temperature lower than. void installation on moving objects like trucks, ships, and so forth. aution rain Tube llow ample space around the air dryer. polyurethane tube of 0mm outer diameter is attached as the drain tube for I to and IU,. Use this tube to discharge drainage. o not use the drain tube in an upward direction. o not bend or crush the drain tube. (Operation of auto drain will stop and water will flow out through the air outlet.) aution Power Supply <00V> Insert the power supply plug into an exclusive 00V power outlet. Install a circuit breaker (0) at the power supply. e sure to ground the power supply prior to use. Multiple-branch wiring is dangerous as it causes over-heating. o not extend the power supply cord length using an extension cord. voltage drop may cause the air dryer to stop operating. Use a circuit breaker having a sensitivity current of m or less and a rated current of 0. xclusive 00V power outlet <00V> onnect the power supply to the terminal block. Install a suitable circuit breaker applicable to each model. aution e careful to avoid errors in connecting the air piping to the compressed (IN) and outlet (OUT).

Valve closed Valve open When tightening piping at the air inlet/outlet tube, the nozzle should be held firmly with a pipe wrench. (I to, IU to ) Variation of operating conditions may cause condensate to form on the surface of the outlet piping. In the case of models larger than I and IU, roll thermal insulation around piping to prevent condensate from forming. Vibration caused by the compressor should not be transmitted through air piping to the air dryer. o not allow the weight of piping to be applied directly to the air dryer. -7- H T I MG M Misc.

When compressed air temperature is too high When compressed air flow rate is too high When ambient temperature is too high ( or higher) When power supply is beyond rated voltage by ±0% When ventilation port is obstructed by a wall or clogged with dust aution ompressor ir elivery Use an air compressor of 00 l/min or greater air delivery with I to /IU,, and 0 l/min or greater air delivery with I to /IU to. aution Time elay for Restarting llow 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, the operating light goes off and the dryer will not be activated. aution rank ase Heater Please wait three minutes! crank case heater is installed on I70. nergize the crank case heater hours prior to operation of the dryer to prevent trouble occurring in the refrigerant compressor. Since the auto drain of I to /IU to is designed in such a way that the valve remains open unless the air pressure rises to 0.5MPa or higher, air will blow out from the drain discharge port when the air compressor starts up until the pressure increases. Therefore, if an air compressor has a low air delivery, the pressure may not be sufficient. aution uto rain The auto drain may not function properly, depending on the quality of compressed air. heck its operation once a day. leaning of Ventilation rea aution Remove dust from the ventilation area once a month using a vacuum cleaner or an air blow nozzle. -7-
