INSTALLATION (FIG. B)
• HW supply temperature: 55 - 85°C (the differential between the hot water and the cold water must
be at least 50°C.
• CW supply temperature: 5 - 20°C.
• Drill a hole Ø 34mm on the washbasin mounting surface e and mount the mixer.
If necessary, temporarily remove the stopcocks i to make the fitting easier.
• Tighten the 2 screws g onto the flange f. 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 M½" stopcocks i, making sure the hot and cold water
supplies are connected to the correct sides. The presence of filters at the inlets of the stopcocks
is obligatory for the protection of the flow rate regulators found in the connectors.
These filters enable the restriction of impurities in the flexibles in order to maintain the thermostatic
mechanism in an operational state, guaranteeing the temperature regulation.
• Take care not to pinch the flexible hoses j.
• 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 d, re-calibrate
the temperature.
REMEMBER
• Our mixers must be installed by professional installers in accordance with current regulations
and recommendations in your country, and the specifications of the fluid engineer.
• Sizing the pipes correctly will avoid problems of flow rate, pressure loss and water hammer
(see calculation table in our brochure and online at www.delabie.com).
• Protect the installation with filters, water hammer absorbers and pressure reducers to reduce
the frequency of maintenance (recommended pressure from 1 to 5 bar (100 to 500 kPa) maximum).
• Install stopcocks close to the mixer to facilitate maintenance.
• The pipework, filters, non-return valves, stopcocks, bib taps, cartridge and all sanitary fittings should
be checked at least once a year, and more frequently if necessary.
CALIBRATING THE TEMPERATURE (FIG. C & D)
Our mixers are pre-set at the factory under 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
(41°C). The control lever should be repositioned to the corresponding temperature (Fig. C) :
• Turn the control lever a to the maximum hot water position d.
• Measure the temperature using a digital thermometer k.
• Unscrew the grub screw l without fully removing it, using a 2.5mm Allen key, and remove the control lever.
• Using the 2.5mm Allen key, turn the screw on the spindle m clockwise or anti-clockwise to adjust
the mixed water temperature (maximum temperature 41°C).
• Replace the control lever (Fig. D) in position d tighten the grub screw l (Fig. C) then turn the control
lever to position b to check that the flow stops.
To complete commissioning, a cold water failure should be carried out: within one second after isolating
the cold water supply, flow from the valve should stop.
After commissioning, record the following temperatures with a thermometer:
1. Hot and cold water supplies.
2. Maximum mixed water.
3. Mixed water after isolating cold water supply noting particularly the maximum and final temperature.
4. Check equipment, thermometer, etc., used for measurements.
