UdiMatic
11.3 - Application guideline
For the selection of the correct automatic filter, it is imperative to take a number of variables into account.
What is the origin of the water used, is it relatively clean – rainwater - or is it soiled – drain water? Next,
the application of the filtered water is of importance: is it a pre-filtration for a disinfectant, or is it used for
outside irrigation? The table below can be used as a guideline for the choice of the correct UdiMatic filter.
These points are based on the average dirt load, which will determine the flushing frequency.
Please consult your installer with respect to your specific situation.
All our recommendations are without obligation, and we cannot be held liable for any adverse
consequences resulting from these recommendations.
