OPERATION
Shower version (Fig. C) :
• In position (1-a), the sequential thermostatic mixer is in the closed position.
• When lever a is turned anti-clockwise, the mixer starts to deliver cold water at the temperature
of the cold water supply. Continue turning the control lever a, and the water will get progressively
warmer up to position (1-c), which is the maximum temperature setting.
Basin/sink version (Fig. E) :
• In position (1-a), the sequential thermostatic mixer is in the closed position.
• When lever a is turned clockwise, the mixer starts to deliver cold water at the temperature
of the cold water supply up to position (1-b). Continue turning the control lever a, and the water will
get progressively warmer up to position (1-c), which is the maximum temperature setting.
This maximum temperature is pre-set at the factory between 39°C and 41°C with cold and hot water
pressures balanced at 3 bar dynamic pressure; HW T°= 65°C +/- 5°C and CW T°= 15°C +/-5°C.
When using a filtration device or similar system at the spout outlet or shower head, the flow rate must
be higher than 4 litres per minute to avoid cross flow between the hot and cold water.

GENERAL CHARACTERISTICS

Technical Characteristics:
• Mixed Water adjustment:
- Basin/Sink: from cold water up to 41°C. Temperature limiter set at 41°C.
- Shower: from cold water up to 39°C. Temperature limiter set at 39°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.
• Flow rate regulated at 9 lpm (+/-1) for shower models (6 lpm for the H9641 model with the regulator
integrated in the shower head), regulated at 7 lpm for basin/sink models.
Safety:
• If the hot or cold water fails, the mixed water will shut off within 2 seconds.
• For anti-scalding safety the hot and mixed water temperature differential must be at least 15°C.
• Check the anti-scalding failsafe every two months and as often as necessary depending on the water
quality. Shut-off the cold water and check that the hot water stops within 2 seconds.
Note: The anti-scalding safety is active if the cold water supply fails.
If, instead of cold water, hot water returns through a mechanical mixer, there is no anti-scalding safety.
DELABIE recommend installing a non-return valve on the cold water supply to the mechanical mixer.
INSTALLATION (Fig. A & B)
Reminder: Ensure that hot water is always delivered from the left side (letter H on the mixer body)
Deck-mounted basin version (Fig. A):
• Drill 2 holes Ø22, 200mm centre-to-centre, and mount the mixer with the pillars.
• Connect to water supply using ½" connectors. It is also possible to connect using biconal Ø15 connectors.
Wall-mounted basin/sink version (Fig. B) with 150 or 200mm centres depending on model.
• Off-set connectors enable adjustable pipe-centres.
Mixers with standard connectors: (ref. 856794.2P)
1. Using PTFE tape or waterproof sealant on the ½" threaded connector, tighten offset connectors a
at right angles to the wall. Ensure a waterproof seal between the supply pipes and the finished
wall surface.
2. Mount the conical cover plates b and adjust offset connectors a to fit, ensuring that the mixer
is horizontal a.
• Mount the mixer so that the hot water inlet is on the left side and the outlet towards the bottom.
