8.7 - Instructions for cleaning the screen
It is recommended to take out the filter screen for cleaning and checking every one year or when head-loss
does not decrease after three repetitive flushing cycles due to differential pressure switch.
Gently clean the screen using a bristle brush, never use a steel brush.
NOTE:
If a bristle brush does not remove particles from screen, immerse screens in an acid or alkaline
solution for some time, then rinse it thoroughly. Recommended solution: 1% - 2% Hydrochloric Acid (HCl),
