- When using an adhesive, ventilate the space sufficiently, prohibit the use of a fire in the vicinity, and do not
inhale adhesive vapors directly.
- If an adhesive gets into contact with your skin, wash it off immediately. If you feel sick or find any
anomaly, receive a physician's diagnosis and take appropriate measures promptly.
- Take care in doing work at low temperatures. Solvent vapors are hard to evaporate and are likely to
remain. (Solvent cracks may occur, damaging the equipment.) After assembling the piping system, open
both ends of the piping and use a fan (of the Low-Voltage Type) or something similar to ventilate the
space, thus removing the solvent vapors.
- Use the appropriate Asahi AV cement.
- Conduct a water test at least 24 hours after joining the pipes with an adhesive/cement.
