8. Maintenance
We recommend a planned maintenance contract with
an installation company
In accordance with DIN 1988, part 8, the following measures
must be taken:
8.1. Inspection
8.1.1. Rinse filter
Frequency: at least every 2 month (depending on local
operating conditions
• Non-compliance can lead to the filter becoming
blocked This results in a drop in pressure and
decreasing water flow
• The filter meshes are made of stainless steel. A red
coating as a consequence of rust from the pipelines
has no influence on function or the way the filter
works
To be carried out by an installation company or the
operator.
Filtered water can be drawn during rinsing.
If rinsing is into a container, then a suitable container
must first be put underneath.
1. Open the ball valve by turning the rinse knob
• Rinse knob must be vertical
2. Close the ball valve after approximately 15 seconds
A longer reverse rinse period may be necessary if the
filter is very dirty (Replace filter mesh see Servicing)
