11. Installation procedure
- When suspending and supporting a valve, take care and do not stand under a suspended
valve.
- Be sure to conduct a safety check on all hand and power tools to be used before beginning
work.
- When conducting piping work, wear personal protective equipment appropriate to the
contents of work. (Failure to do so may cause an injury.)
- Take care not to over-tighten the Union nut. (The valve can be damaged.)
-
Do not use the pipe wrench. (The valve can be damaged.)
- When installing pipes and valves, ensure that they are not subjected to tension,
compression, bending, impact, or other excessive stress.
- When loosening the Union nut on the Carrier side, fix the End connector (hold it with your
hand) and do work. (If the end connector turns, the union will turn together, resulting in the
union and ball separating from the body.)
- If the union is loosened, retighten the union.
- When installing, disassembling, or reassembling the piping, fix the end connector.
- Before a water test, be sure that the Union nut is tightly fastened.
- Fasten the Union nut while avoiding the parallelism and axial misalignment of the flange
surface.
- When connecting a ASAHI AV Valve to metal piping, take care not to let the pipe stress on
the ASAHI AV Valve.
