1.2 Hazard classifications/ Hazard Warning Labels
To ensure the safety of the operators, potential hazards are classified and marked with warning labels.
Confirm the potential hazards and positions of the labels before operation.
1.2.1 Hazard of Electricity
1.2.2 Hazard of Hot Surface
1.2.3 Danger of Compressed Air Circuit
- Transportation, installation, and maintenance involve risks and should only be carried out by
people who have sufficient knowledge and experience about the product and its incidental
device.
- If there is abnormality, take actions below according to the operation manual.
- Read carefully the Chapter 6 Troubleshooting before taking actions.
- Do not start the product in any trouble. If failure occurs, immediately stop the product, and
contact maintenance personnel or a person who has sufficient knowledge and experience
about the product and its incidental device.
The product has surfaces that can reach high temperatures during operation. What is more,
there is also the danger of burn injury due to remaining heat after the power supply is cut.
Therefore, wait until the temperature of hot parts become 50oC and below.
WARNING
Before replacing or cleaning parts, be sure to bleed compressed air remaining inside of the
product until the gauge indicates “0”. If there is no relief to the pressure, high pressure can
propel objects at high velocity when unscrewing parts and cause injury.
WARNING
WARNING
Inside of this product, there is a power-supplying section with high voltage separated by the
cover panel. Do not operate the product without the cover panel.

3.2.3 Air piping
Connection of the inlet and outlet of compressed air should be made removable by using union and
so on.
When an air fitting is connected with the body of the product, hold the pneumatic piping at the body
with a pipe wrench and tighten.
Avoid applying the piping weight directly to the dryer. When parts including air filter are mounted to
the fitting of the inlet and outlet for compressed air, support the parts with the bracket to prevent
force being applied to the product.
Be careful not to let the vibration of the air compressor transmit.
The piping surface temperature will be the same as the inlet temperature of the compressed air.
Wrap the piping with insulator when the surface temperature exceeds 60oC.
When the inlet temperature of the compressed air exceeds 65oC, install the aftercooler after the air
compressor or decrease the temperature of the place to install the air compressor to keep the
temperature at 65oC or lower.
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 made it possible to do maintenance without stopping the air compressor.
Metal flexible tube for air inlet and outlet piping may make noise. Please change the piping to steel
tube.
If rapid pressure fluctuation or flow change occurs, install a filter on the dryer outlet to prevent drain
from splashing.
Depending on the operating conditions, condensation might occur around the outlet piping surface.
Wrap insulator around the piping to avoid condensation.
Do not remove the
panel screws at
piping port.

3.2.4 Drain tube
- A drain tube of 12mm O.D. is included as an accessory. The outlet end of the tube is released to
atmosphere and lets the drain flow through the tube.
(When customers prepare the drain tube, keep its length at 5m or less and the I.D. at 8mm or larger for
correct operation of the auto drain)
- 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.
- Prevent the drain tube from having a rise in its piping.
- Do not bend or crush the drain tube. When installing the product, take care not to place the product on
the drain tube.
- For piping the drain tube to the back of the dryer, use the holder included as an accessory.
- During the dryer operation, keep the ball valve open at all times. When the ball valve is closed,
the condensate drain cannot be discharged.
- Keep the drain cock at “S” side. If the drain cock is at “O” side, compressed air continues to
bleed.
