maintenance
and
inspection
(including
cleaning
of
the
screen).
※You will be unable to maintain (including cleaning of the screen) and inspect
the product if there is not enough space.
（４）Upon
piping, please make sure that Unnatural force,bending,or vibration will not be
transmitted to the products.
※In adequate piping can result in leakage.
（５）Please make sure that the connections with the piping are secure.
※Inadequate connections can result in physical damages due to fluid outflow
caused by vibrations and other reasons.
※Inadequate connections can result in fluid outflow.
（１）Installiing pressure gauges at inlet and outlet side may help to detect the clogging
upof the screen.〔４．１
Example of piping【Figure3】〕
（２）When using at outside,painting is needed to avoid from the rust.
５．Operation
５．１

（１）Please make sure that there is no danger at the pipe end before pouring the fluid.
※You may get scalded in case hot fluid spouts out.
※Physical damage may occur from fluid outflow.
Caution
（１）Use the strainer in condition of maximum pressure loss of below ０.１MPa.Also
keep cleaning the screen periodically.
※The Screen may be damaged.
（２）Always follow the sequence when switching the cock.
※The product may not work properly.〔５．２
Operation method Reference〕
（３）There are some allowable leakages from the cock, so when cleaning the screen,
