OPERATION
• Press the push-button control to open the valve.
• Mixer: temperature control via the side lever.
• Automatic shut-off after ~7 seconds for washbasins,
~3 or 7 seconds for urinals (depending on the model)
and ~30 seconds for showers (-10/+5 at 3 bar).
INSTALLATION
• Tap: supply with cold water (insert the blue or grey marker)
or mixed water (insert the red marker).
• Mixer: supply with cold water and hot water at 50°C (maximum
recommended 70°C), and balance the pressure between
the hot and cold water (ΔP < 1 bar). Maximum supply pressure
is 10 bar (we recommend 1 to 5 bar dynamic pressure).
Take care not to pinch the PEX flexibles (Fig. A).
• For shower and urinal models: respect the direction of the water
flow, see arrow on the valve body.
Deck-mounted Washbasins
• Drill a Ø 21mm diameter hole for installing taps and Ø 34mm
for mixers.
• Mount the mixer/tap body onto the washbasin and tighten
the screws:
- Tap: tighten the 3 stainless steel screws on the back-nut
(Fig. B), for models with a reinforced back-nut. For models
with a single back-nut, tighten directly on the back-nut.
- Mixer: tighten the bolts (Fig. C) on the fixing flange.
Install the filters (Fig. D) supplied, exactly as shown
in the diagram. They will protect the non-return valves
from damage.
• Ensure a waterproof seal between the mixer and the work
surface that is appropriate for the type of installation.
• Connect the water supply and operate the valve several times
to stabilise the time flow.
