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 (+5/-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). Ensure that hot water
is always delivered from the left side and cold from the right. Maximum supply pressure is 5
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 simple back-nut, tighten directly on the back-nut.
- Mixer: tighten the bolts (
fig. C
) on the fixing flange. Install the filter joints (
fig. D
) supplied,
exactly as shown in the diagram. They will protect the nonreturn 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
Wall-mounted Model
• Tighten the tap directly onto the fittings recessed in the wall using the 15/21 supply tails.
• Connect the water supply and operate the valve several times to stabilise the time flow.
Wall-mounted Exposed Models (excluding ref. 747801)
• Mount the valve on the wall using the screw/screws provided (use rawl plugs that are
suitable for the type of wall).
• Connect the water supply and operate the valve several times to stabilise the time flow.
Wall-mounted Exposed Shower Kit (ref. 747801) (fig. H)
• Fix the shower head
so that the nozzle
is 2.10m from the floor.
• Assemble the column
and the valve
.
• Insert the column into the hole beneath the shower head
. Fix the shower head
onto
the wall (use rawl plugs that are suitable for the type of wall).
• Position the collar
in the middle of the column to cover the joint. Fix the collar
and
the valve
to the wall (use rawl plugs that are suitable for the type of wall).
• Connect to the water supply and ensure that all the connections are waterproof. Operate
the valve several times to stabilise the time flow.
