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, turn the the control knob towards
the "-" to the limit, then press the red button with a tool and continue to turn the control towards the "-".
Technical characteristics:
• If the cold water temperature is above 25°C, the mixer will not close or it will open by itself,
even if it is in the closed position (the cold water system should be maintained below 20°C where
possible to comply with current Legionella guidelines).
• 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 35 - 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).
• Reference H9768TP : MW temperature range: from 35 - 41°C. The temperature limiter is set at 41°C.
• 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.
