OPERATION & TECHNICAL INFORMATION
How to operate (Fig. A):
• In position (1-a), the single lever thermostatic mixer is closed.
• When the control lever (1) is turned clockwise, the mixer will start to deliver cold water at the
temperature of the cold water supply in position (1-b). Continue turning the control lever (1),
and the water will get progressively hotter up to position (1-c), which is the maximum hot water position.
• The maximum temperature is pre-set at the factory between 39°C and 41°C with the following
parameters: hot and cold water pressures are balanced at 3 bar dynamic pressure; hot water
temperature at 65°C +/- 5°C; and cold water temperature at 15°C +/-5°C.
Technical Characteristics (Fig. B):
> Flow rate:
- Mixed water temperature 39°C at 3 bar pressure: 6.5 litres/min.
- Mixed water temperature 39°C at 1 bar pressure: 4.5 litres/min.
- If the pressure is at 0.5 bar, the flow rate will be 3.5 litres/min.
> Safety:
- If the cold or hot water fails, the mixed water will shut-off within 2 seconds.
- The anti-scalding safety is active if the temperature differential between the hot water and mixed
water is more than 15°C.
- Check the anti-scalding failsafe every two months and as often as necessary depending
on the water quality. Shut-off the cold water and check that the hot water stops within 2 seconds.
When using a filtration device or similar system at the spout outlet or shower head, the flow rate must
be higher than 4 litres per minute to avoid cross flow between the hot and cold water.
Note: The anti-scalding safety is active if the cold water supply fails.
If, instead of cold water, hot water returns through a mechanical mixer, there is no anti-scalding safety.
We recommend installing a non-return valve on the cold water supply to the mechanical mixer.
INSTALLATION (Fig. B)
• Drill a hole Ø 34mm on the washbasin mounting surface (2) and mount the mixer. If necessary,
temporarily remove the stopcocks (5) to make the fitting easier.
• Tighten the 2 screws (3-a) onto the flange (3). Ensure a suitable waterproof seal between the mixer
and the work plan appropriate to the type of installation.
• Connect the water supply to the mixer with the M1/2" stopcocks (5), making sure the hot and cold
water supplies are connected to the correct sides.
• Take care not to pinch the flexible hoses (6).
• To ensure the mixer functions correctly, balance the hot and cold water pressure (ΔP<1 bar).
Recommended pressure: 3 bar. Maximum pressure: 5 bar.
• If the hot water temperature is not correct when the control lever is in position (1-c), re-calibrate
the temperature.
CALIBRATING THE TEMPERATURE (Fig. C & D)
Our mixers are pre-set at the factory at 3 bar pressure, with hot and cold water supply pressures
balanced, and hot water temperature at 65°C +/- 5°C and cold water temperature at 15°C +/-5°C.
If the conditions of use are different, the mixed water temperature may differ from the set temperature
(40°C). The control lever should be repositioned to the corresponding temperature (Fig. C):
• Turn the control lever (1) to the maximum hot water position (1-c),
• Measure the temperature using a digital thermometer (7).
