INSTALLATION
Remember: the hot water supply must always be connected on the left.
• Mixer: supply with cold water and hot water at 70°C maximum
(we recommend 50°C in public buildings and 55°C in healthcare facilities to comply with UK Legionella
control guidelines).
• Pressure: 1 - 5 bar (100 - 500kPa), we recommend 3 bar (300 kPa).
• Maximum pressure differential at the inlets: 1 bar.
• Take care not to pinch the flexibles (Fig. B).
OPERATION
• The sequential mixer is in the closed position. When the control lever is turned clockwise,
the mixer will start to deliver cold water at the temperature of the distribution system.
Continue turning the control lever and the water will get progressively hotter up to the maximum
temperature limit.
• To undertake a thermal shock at the temperature of the hot water in the system (Fig. AG),
override the maximum temperature limiter using a ballpoint pen or a pointed object while turning
the control lever to the full hot water position.
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.
INSTALLING THE MIXERS (FIG. A - D)
• Mount the mixer body on the washbasin or sink (drill hole Ø 34mm) and tighten the two nuts
on the threaded rods.
• Connect using F3/8" PEX flexibles*.
• Ensure a suitable waterproof seal between the mixer and the work plan appropriate
to the type of installation.
* For copper tails or 15mm compression fitting options please contact Technical Support.
