Maintenance
In order to comply with EN 806-5, water fixtures must
be inspected and serviced on an annual basis.
As all maintenance work must be carried out by an
installation company, it is recommended that a
servicing contract should be taken out.
CAUTION!
Risk of burns due to hot water and hot surfaces.
Wear safety gloves!
In accordance with EN 806-5, the following measures must
be taken:
6.1 Inspection
1.
Close shut-off valve on outlet

Check outlet pressure using a pressure meter when
there is zero through-flow
• If the pressure is increasing slowly, the valve may
be dirty or defective. In this instance, carry out
servicing and cleaning (See 6.2 Maintenance)
