Adjusting The Flow Rate - Delabie 2200 Manual Del Usuario

INSTALLATION
• Mixer: Supply with cold water and hot water at 70°C maximum (we recommend 45°C to avoid
the risk of scalding).
• Pressure: 1 - 5 bar (100 - 500kPa), we recommend 3 bar (300kPa). Maximum pressure differential
at the inlets: 1 bar.
• Take care not to pinch the flexibles (Fig. B).
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 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
Standard mixers:
• Deck-mounted, single hole washbasin or sink mixers (Fig. A):
- Mount the mixer body on the washbasin or sink (drill hole Ø 34mm) and tighten the two nuts
on the threaded rods. For the 2220 range, block the (one) nut.
- Connect using F3/8" PEX flexibles*.
- Ensure a suitable waterproof seal between the mixer and the work plan appropriate
to the type of installation.
• Wall-mounted mixers for sinks and showers or shower/baths (Fig. C):
Off-set connectors enable adjustable pipe-centres (150mm ±20).
• Mixers with standard connectors:
1) Using FTPE tape or waterproof sealant on the 1/2" threaded connector, tighten the off-set connectors
at right angles to the wall.
2) Mount the conical cover plates and adjust connectors to fit, ensuring that the mixer is horizontal.
Tighten the cover plates onto the offset connectors by hand.
3) Insert the waterproof washers into the valve nuts and tighten the mixer using a spanner.
• Mixers supplied with STOP/CHECK connectors:
see the installation guide supplied with the 2 connectors (ref. 855755UK.2P).
* For copper tails or 15 mm compression fitting options please contact Technical Support.
ANTI-POLLUTION PROTECTION
Compliance with the European standard EN 1717
• Our mixers for showers, shower/baths and retractable shower heads have non-return valves
to prevent dirty water flowing back into the system (for non-return valve location see (Fig. D)).
These should not be removed in any circumstance.
• The sink, shower and shower/bath mixers should be installed in accordance with the Water Supply
(Water Fittings) Regulations 1999 and in accordance with local health or other appropriate regulations
(Department of Health, directives, technical memoranda, etc.).

ADJUSTING THE FLOW RATE

Ceramic cartridge Ø 40mm:
• Washbasin/sink mixers: Flow rate limited to 5 lpm at 3 bar.
• Shower mixers: Flow rate regulated at 9 lpm.
