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 ball valve on the outlet side of the refilling
combination
2.
Check outlet pressure on pressure gauge when no
flow is occurring
• If the pressure is increasing slowly, the valve may
be dirty or defective. In this instance, carry out
servicing and cleaning (See 6 Maintenance)
3.
Slowly open the ball valve on the outlet side of the
refilling combination
6.1.2 System disconnector
1.
Close shut-off valve on inlet
2.
Open the drain point on the inlet side of the shut-off
ball valve.

Troubleshooting
Problem
Beating sounds
Water is escaping from refilling
combination
No or too small water flow rate
Refilling combination change not into
flow position
Refilling combination opens and closes in
short time intervals (pump)

Observe the local requirements regarding correct waste
recycling/disposal!
Cause
Non return valve is faulty
Sealing elements are contaminated or
worn
Refilling combination is not fitted in flow
direction
Ball valves up- or downstream of refilling
combination are not fully open
Drain cocks at the shut off ball valves up-
and downstream of the refilling
combination are not fully close
Pressure reducing valve is not set to the
desired outlet pressure
Check supply pressure with reaction
pressure
plant downstream leaky
Non return valve is contaminated or worn Call our Technical Customer Services

• If the differential pressure between middle and
inlet chambers is less than 10 % of the inlet
pressure, the system disconnector moves into
disconnect position (back suction). The inlet side
backflow preventer closes and the discharge valve
opens.
Discharge valve does not open, replace backflow
preventer!
Close the drain point on the inlet side of the shut-off
ball valve
Slowly open shut-off valve on inlet
Open sampling point
Refilling combination changes into flow position.
Optical control backflow preventer of location and
tightness.
If water exits at the refilling combination, call the
technicalcustomer support service!
