Avoid locations where temperature substantially changes.
Avoid locations where strong magnetic noise occurs. (Avoid locations where strong electric field,
strong magnetic fields, or surge voltage occur).
Avoid locations where static electricity occurs or conditions which make the product discharge static
electricity.
Avoid locations where high frequencies occur.
Avoid locations where damage is likely to occur due to lightening.
Avoid installation on machines used for transporting, such as vehicles, ships, etc.
Avoid locations at altitudes of 2000 meters or higher.

Necessary maintenance space
Front face: 1.0 m
Rear: 1.0 m
Top: 1.0 m
Right side: 1.0 m
Left side: 1.0 m
Avoid locations where the ventilation grille is obstructed.
Avoid locations where the air dryer will draw in high-temperature air discharged from an air
compressor or other dryer.
Avoid pneumatic circuits where rapid pressure fluctuations or flow speed changes are generated.
3.2.2 Installation
The product should be installed on a vibration-free, stable, horizontal flat surface.
Refer to the 7.3 Dimensions of the Chapter 7.
We recommend the anchor bolt sets.
Do not use or store the product in conditions of compressed air or an environment

3.2.3 Air piping
Connect compressed air inlet and outlet using a JIS10K flange specified in Chapter 7- 7.1
Specifications
It is recommended to install a main line filter in the air inlet piping. Main line filter prevents the auto
drain from malfunctioning by stopping rust and particles.
Be careful not to let the vibration of the air compressor transmit.
When the pressure of the air source fluctuates a lot, install an air tank.
Before piping, flush the inside of piping to eliminate foreign matter such as particles, seal tape or
liquid gasket. Entry of the foreign matter may cause cooling failure or drain discharge failure.
Use pipes and fittings that have enough endurance against the operating pressure and temperature.
And connect it firmly to prevent air leakage.
Provide bypass-piping to make it possible to do maintenance without stopping the air compressor.
If rapid pressure fluctuation or flow change occurs, install a filter on the dryer outlet to prevent drain
from splashing.

3.2.4 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.
3.2.5 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)
Power supply cable specification
Prepare the power supply cables below.
Power supply cable: 10AWG (5.5mm2or 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.
