REMEMBER
• Our mixers/taps must be installed by professional installers in accordance with current
regulations and recommendations in your country, and the specifications of the fluid engineer.
• Sizing the pipes correctly will avoid problems of flow rate, pressure loss and water hammer
(see calculation table in our brochure and online at www.delabie.com).
• Protect the installation with filters, water hammer absorbers and pressure reducers to reduce
the frequency of maintenance (recommended pressure from 1 to 5 bars maximum).
• Install stopcocks close to the mixer/tap to facilitate maintenance.
• The pipe work, stopcocks, bib taps and all sanitary fittings should be checked at least once a year,
and more frequently if necessary.
CONNECTION
• Respect the direction of the water flow (see arrow engraved on the mixer/tap body).
• Install the filters supplied to protect the solenoid valve(s) from foreign bodies.
• Connect the solenoid valve(s) to the terminal EV (fig. G) via the rubber compression gland:
- RED wire(s): EV+ terminal
- BLUE wire(s): EV- terminal
• Connect the sensor cable to the BMR terminal (fig. G) via the rubber compression gland:
- WHITE wire: terminal B
- BROWN wire: terminal M
- RED wire: terminal R
• Do not cut or lengthen the detector cable (500cm length available on request).
• Connect to the power supply using an insulated twin-core power supply cable
(2 x 1.5 or 2 x 1, ext. Ø7 - 8mm to ensure a waterproof connection) to the 220-240V terminal on the
electronic unit. A circuit breaker must be installed ahead of the electronic control unit
(see ELECTRICAL SUPPLY section).
• Mount the wall unit under the washbasin at least 50cm above the floor with the compression glands
facing downwards.
• Tighten the nuts on the compression glands.
• Replace the fixing screws, cover and seal then close the box.
HOW THE ELECTRONIC UNIT OPERATES (fig. J)
• The YELLOW LED i (ALIM) is lit when the power supply is operating.
• The GREEN LED j (EV) is lit when the sensor detects the user's hands and the solenoid valve opens
the water flow. When the hands are removed and after a comfort shut-off delay, the flow stops
and the GREEN LED goes out.
• The RED LED h (SECU) is lit and the flow of water stops if the sensor detects hands (or any other
object) continuously for 45 seconds; the anti-blocking security is activated. Once the hands or object
are/is removed the system is reset and a new cycle can commence.
• For the electronic unit to operate correctly the ambient temperature should be between 5 - 40°C.
