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.
In accordance with EN 806-5, the following measures must
be taken:
6.1
Inspection
6.1.1 Pressure reducing valve
1.
Close shut-off valve on outlet
2.
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)
3.
Slowly open shut-off valve on outlet
6.1.2 Check valve
1.
Close shut-off valve on inlet
2.
Open test valve
•
Until the pressure is released, some water will flow
out of the test valve. After a short period of time the
water flow should stop. If the water continues to
drip or run, then the check valve must be replaced
(see 6.2 Maintenance)
3.
Close test valve again
4.
Slowly open shut-off valve on inlet
6.2
Maintenance
Do not use any cleansers that contain solvents and/or
alcohol for cleaning the plastic parts, because this can
cause damage to the plastic components - water
damage could result.
Detergents must not be allowed to enter the
environment or the sewerage system!
1.
Close shut-off valve on inlet
2.
Release pressure on outlet side (e.g. through water
tap)
3.
Close shut-off valve on outlet
4.
Fit adjustment knob
CAUTION!
There is a spring in the spring bonnet. It may cause
injuries if the spring is derailing.
