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 60 o C.
When the inlet temperature of the compressed air exceeds 65 o C, install the aftercooler after the air
compressor or decrease the temperature of the place to install the air compressor to keep the temperature at 65
o C 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.

from the ventilation outlet. 3) Open the IN and OUT side valves slowly. Ensure the bypass valve is completely closed.
Confirm that there is no air leakage. 4) The fan keeps starting and stopping depending on the compressed air and ambient temperature
conditions, but the compressor keeps operating continuously, and the evaporation thermometer stays within the green area. When the refrigerant pressure gauge indicator is in the area higher than the green area, refer to Chapter 6 Troubleshooting.
5) After supplying compressed air for a while, the drain will be discharged from the drain tube automatically.
6) Continue the operation.
Only someone who has enough knowledge and experience about the product and
incidental devices should operate or shut down the product.
CAUTION
- Frequently switching ON and OFF leads to malfunction.
- The auto drain is normally open and the valve closes when the air pressure is 0.1MPa or
more. When the IN side valve starts to open, air bleeds from the drain outlet until the
pressure reaches 0.1MPa. The pressure may not reach 0.1MPa when the air compressor
discharge flow rate is small.
- Dehumidified drain may flow into the secondary piping if there is a sudden change of
pressure or flow speed. Do not use the product where these conditions are present.

4.4 Cautions for re-start
Allow at least 3 minutes before restarting the product. If the product is restarted within 3 minutes after
being stopped, the protection circuit will be activated, and the dryer will not start.
When operation does not start, restart it referring to the Chapter 6 Troubleshooting.
4.5 Check points before restart
When starting operation, check the following points. Immediately stop operation if any abnormality
occurs. Turn off the switch with lamp and shut off the breaker of the power supply.
- There should be no leakage of compressed air.
- Compressed air pressure, temperature, flow rate and ambient temperature are within the specifications of the product.
- Confirm that drain comes out of the drain tube.
- The evaporation thermometer is in the green area.
- Drain should not be exhausted from the compressed air outlet of the air dryer.
- There should be no abnormality with noise or vibration or odor from the product.
4.6 Cautions when the product is shut down for an extended period of time
- When the product is not used for longer than 24 hours, turn off the operation switch or power supply for safety and saving energy. It is recommended to discharge pressure from the compressed air piping.
- The residual drainage in the air dryer may splash over the outlet when the operation is re-started, so it is recommended to install a filter on the outlet of the air dryer.
