- 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 anomaly, receive a physician's diagnosis and take appropriate measures promptly.
- Do not under any circumstances try to insert a pipe into another fitting or valve by striking
it. (Which may break the piping.)
- 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.
- Do not apply more adhesive than necessary. (The valve can be damaged due to solvent
cracking.)
- The Union nut of this product is fastened lightly so that it can be loosened easily. Be sure
to remove the End connector before carrying out the work. (Failure to so may cause
external leakage.)
- Use the appropriate Asahi AV cement.
- Conduct a water test at least 24 hours after joining the pipes with an adhesive.
