7.5 Strainer cleaning procedure
1.
If fluid is hot, do not touch the product directly with bare hands.
* Failure to follow this notice may result in scalds.
1.
Clean the strainer regularly at least once or twice a year.
* Too much deposit of scales or the like decreases the flow rate, which prevents the product from
functioning properly.
2.
When the strainer cap is removed, receive fluid in a container. (See the Figure below.)
1.
Close the stop valve at the inlet side and open the stop valve at the end, and remove the internal
pressure from the product completely.
2.
Turn the strainer cap counterclockwise, and remove it.
3.
Remove the strainer from the strainer cap, and wash it in water, and remove deposited scale.
4.
After cleaning, reinstall the strainer and strainer cap in the body.
5.
Open the stop valve at the inlet side, and check that there is no leakage from the strainer cap. When
there is a leakage, replace the O-ring.
6.
Open the stop valve at the end, and check that the product operates normally.
