Characteristic curve of flow rate
The solenoid valve is fitted with a flow regulator ex works, which controls the flow rate at 14l/min. Replacing
the flow regulator (article number 243.579.00.1) can reduce the flow rate to 9l/min.

Troubleshooting
The operator can perform the following measures to rectify malfunctions. → See operation manual
966.933.00.0 (mains operation) and 966.934.00.0 (battery operation and self-sustaining).
• Restart the urinal flush control
• Set the flush time
• Optimise the detection distance
• Clean the basket filter
• Replace the batteries
• Charge the rechargeable battery of the self-sustaining power supply
Malfunction Cause Action

unwanted)
Detection distance not set
correctly
▶ Optimise the detection distance.
→ See operation manual.

Battery warning level 1
(4 short signal tones upon entering the
detection range)
Batteries dead
Rechargeable battery
empty
▶ Replace the batteries.
▶ Charge the rechargeable battery
of the self-sustaining power
supply.
