Flow Pressure, Hot and Cold - bar
Hot Water Supply Temperature -°C
Cold Water Supply Temperature - °C
Mixed Water Temperature - °C
OPERATION
When using a terminal filter or other device on the shower head or spout outlet, the flow rate at the outlet
must be more than 4 litres per minute to prevent cross flow between the hot and cold water.
GENERAL & TECHNICAL CHARACTERISTICS
General characteristics:
If the cold water supply fails and if the selected mixed water temperature is below 43°C, the hot water
supply will shut off (response time ~2 seconds). Filters in the mixer inlets protect the thermostatic element.
Note:
References H9768, H9768S, H9769 and H9769S: for cold water only, press the red button and turn
the control knob towards the "-" to bypass the limiter and go to the cold water position. Then, turn the
temperature control knob to the mixed water position, otherwise it will be impossible to stop the water flow.
Technical characteristics:
• If the cold water temperature is above 30°C, the mixer will not close or it will open by itself,
even if it is in the closed position.
• The factory pre-set is 38°C, (the small marker on the control knob must align with the 38°C marker),
with a temperature difference of 50°C between the cold and hot water.
• References H9768, H9768S, H9769 and H9769S:
MW temperature range: from 33 - 43°C. The temperature limiter is set at 41°C.
It is possible to increase it to 43°C by manually pressing the button on the control knob c (Fig. A).
• Maximum Hot Water temperature: 85°C.
• Min/max pressure: 1 to 5 bar (recommended 3 bar). Maximum pressure difference at the inlets: 1 bar.
• Safety: the hot water supply will shut off if the cold water supply fails. The hot water failsafe is active
if the hot and mixed water differential is greater than 15°C.
• Flow rate is limited to 9 lpm (± 1) at 3 bar.
• Temperature control is on the right hand side and flow rate is on the left hand side.
