3 - Operating faults:
Carefully check that any fault really is due to the appliance.
Observed faults
Causes and solutions
The water is not running at the right temperature.
Check that the water supply is not cut and that the connec-
tions have been made to the inlets. Was the calibration carried
out properly?
Water runs but slowly.
Hot or cold water production is not sufficient.
Blocked or clogged up filter.
When starting the new appliance, only hot or cold water runs.
Water inlets are fitted the wrong way round.
Mixed water runs in fits and starts and very slowly except at
one or other extreme temperature.
Hot or cold flow is restricted.
Check that the cartridge filters are clean.
1 - Installation:
On a stopcock (chrome plated) with wall plate.
2 installation possibilities:
- parallel to the wall (diagram 1 page 2)
or
- perpendicular to the wall (diagram 2 page 2).
1-1 Assembly
Connect the hot water inlet (+) directly to the stopcock.
Connect the cold water (-) using a hose or a copper tube.
Connect the outlet (M) to the mechanical mixer inlet.
Provide a stopcock on each inlet.
1-2 Rinsing
[recommended step] (diagram B3 page 3)
Unscrew the screw and remove the cap (W), unscrew the nut
(X), remove the cartridge (Z).
Fit the rinsing kit (V) instead of the cartridge and re-tighten the
nut (X).
Supply hot and cold water, rinse the piping by letting the water
flow abundantly.
Turn off the hot and cold water, then unscrew the nut (X) and
remove the rinsing kit (V), refit the cartridge (Z) and re-tighten
the nut (X).
1-3 Adjusting the temperature
[factory set to 38°C] (diagram B2 page 3)
Turn on the water supply to the appliance.
Calibrate the temperature:
- Run the water at the required temperature by turning the ad-
justment ring (Y) in the direction shown by the arrow and using
the temperature marks.
- Note the temperature obtained using a thermometer.
- Remove the adjustment ring (Y) to position the temperature
indicated on it opposite mark (U) on the nut (X) corresponding
to the temperature obtained.
1-4 Refitting the casing
Once the temperature has been set, refit the cap (W) and refit
the safety screw.
2 - Features:
2-1 Flow rate at 3 bar
28 Liters / min
2-2 Supply
The thermostatic mixing valve may be fed by any hot water
heating system, even an instant household heater, provided
that the boiler remains capable of producing very low hot water
flows (3l / min).
- Maximum working pressure: 10 bar
- Minimum working pressure: 1 bar
- Recommended working pressure: 2 to 4 bar
- Maximum hot water temperature: 85°C
- Minimum difference between input temperatures: 10°C
- Maximum pressure difference between hot and cold water:
1,5 bar
- Temperature setting range: 30 to 70°C

Hot, cold and mixed water connections in flat-sealing
construction only for Art.No. 2297320M2 / 2297321M2.
