Precautions
1) Maintenance should be performed according to the procedure indicated in the Operation
Manual. Incorrect handling can cause damage of equipment and device, and operation failure.
2) During maintenance, compressed air can be dangerous when handled incorrectly. The
assembly, handling, repair and element replacement of pneumatic systems should be
performed by a knowledgeable and experienced person.
3) Remove drainage from air filters and mist separator regularly. If the collected drainage is
drained to the downstream side, it can stick inside of the product, causing operation failure
and failure to reach the specified vacuum pressure. If the drain bowl is difficult to check and
remove, the installation of a drain bowl with an auto drain option is recommended.
4) Replace the filter element in the ejector regularly. It is recommended to replace the filter
element when the pressure drop reaches 5 kPa as a guideline. The replacement cycle varies
depending on the operating conditions, operating environment, and supply air quality.
However, if there is a vacuum pressure drop and/or delay in the vacuum (adsorption)
response time which causes problems with the settings during operation, stop the operation
of the product and replace the filter element regardless of the above mentioned replacement
guideline.
5) When the product is to be removed, turn off the power supply, and be sure to cut off the supply
pressure and exhaust the compressed air. Confirm that the air is released to atmosphere.
When mounting the product after the maintenance work, supply compressed air, connect to
the power, check if it functions properly and check for leaks.
6) Do not disassemble or modify the product, other than the replacement parts specified in this
manual.
7) Do not use solvents such as benzene, thinner etc. to clean the product. These can damage
the surface of the body and erase the markings on the body. Use a soft cloth to remove
stains. For heavy stains, use a damp cloth that has been soaked with diluted neutral
detergent and fully squeezed, then wipe up the stains again with a dry cloth.
