Replacement of auto drain
Mount the nipple to the auto drain (included in the same package). Then connect it to the drain inlet of the dryer.
Connect the drain piping to the auto drain outlet. The drain piping should have an internal diameter of 8mm or
more and be 5m or less in length. Make sure that it does not go upwards and it is not bent. The outlet end of the
tube is released to atmosphere, and lets the drain flow through the tube.
Ensure that the ball valve is opened. Refer to 7.3 Dimensions of the Chapter 7.
Using the pressure of the compressed air, the drain will be discharged periodically. Fix the outlet end
of the tube so as not to swing during discharge.

Electrical wiring
3.2.5.1.
Wiring of the power supply cable
Remove the front panel of the product and connect the power cable to the terminal block.
Install the earth leakage breaker on the power supply side. It needs to be prepared by the user.
Allowable power supply fluctuation:
3 phase 200 VAC +/-10% (50Hz); 3 phase 200 VAC to 220V +/-10% (60Hz)
3 phase with different voltage (IDF190 / 240D-9-
): AC220V, 240V, 380V, 400V, 415V, 440V+/-10%
Power supply cable specification
Prepare the power supply cables below.
Power supply cable: 10AWG (5.5mm
2
or greater), cable O.D. Approx. 16mm, 4 cores (including the
ground)
Approx. 1.5m of cable is necessary for wiring in the product.
All electrical work must be carried out in a safe manner by a qualified person in compliance
with applicable national regulations.
-
Be sure to shut off the user’s power supply. Wiring with the product energized is strictly
prohibited.
- Ensure a stable power supply with no surge.
- Install the correct electric earth leakage breaker of the specified leakage capacity and load
capacity referring to 7.1 Specifications to prevent electric shock and burning of the
compressor motor.
- Use a power supply suitable for the specifications of the product.
3 phase power supply type cannot be operated by single phase power supply.
- Be sure to connect the ground connection.
- Never connect the ground to water line, gas pipe or lightning conductor.
- Do not plug too many leads into a single socket. That causes exothermic heat or fire.
- Do not modify the internal electrical wiring of the product.
- For use in Europe, install a breaker compliant with applicable IEC standards to the power
supply of the product.
WARNING
- During drain work, follow the procedure that you define to keep the safety of worker. (ex.
Put on protective glass, apron, and gloves).
- In case that oil gets mixed in the wasted water that is discharged from the auto drain, the
waste liquid treatment is necessary. Handle it following the bylaw or regulation of local
government.
