Maintenance procedure

Precautions during installation
Caution
（１）
When installing, confirm if the direction of fluid flow matches with inlet and
outlet port of the product respectively.
※
If installed in opposite direction, it will not function as designed.
（２）
When installing, reserve the space shown for the maintenance and checking
(cleaning of the screen).
※
It will be impossible to carry out the maintenance and inspection (cleaning of the
screen).
（３）
When installing, do not transmit unreasonable load, bending, vibration to the
products.
※
The leakage problem may occur.
（４）
Carry out the connection with pipes properly.
※
Improper piping connection may cause the leakage of fluid due to vibration or
other cause. With some kind of fluid, there will be a danger of personnel being
scalded.
The fluid flowed out of pipe end may cause some material damages.
（１）
In case installing pressure gauge at backward and forward of strainer, clogging
can be checked by differential pressure.
［

］
（２）
Install strainer with the cap parts facing downward.
［

．
Piping example

］
However, install strainer with cap parts facing sideways in case of steam piping
so that condensate accumulation is minimized.

（３）
if fluid flows from bottom to top, install a blow valve in order to remove scale
accumulated at the bottom of riser pipe.

６．２
Warning and Caution at the point of use
Warning
（１）
In case the high temperature of fluid is applied, keep the bare hand off the
strainer.
※
It may cause the personnel being scalded.
（２）
Do not tighten the cap after flowing the fluids to the valve.
※
The gasket will be broken and leads to have a leakage.
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.
