Delabie SECURITHERM 792314, Quick Start Manual

Page: 12 / 32

OPERATION
Electronic panels
• Trigger water flow:
- by nearing hand 4cm from the infrared presence detector for battery-operated versions.
- by pressing the electronic push-button for mains supply versions.
• Voluntary water shut-off or automatic after 1-minute of flow (safety timing).
• Temperature selection on the thermostatic mixer.
• Automatic duty-flush every 24 hours after last use: this periodic 60 sec. flush helps prevent the risk
of legionellosis. It prevents water stagnation and the development of bacteria in the pipework.
Time flow panels
• Open by pressing the push-button.
• Temperature choice on the thermostatic mixer.
• Timed automatic shut-off after ~30 sec. (+5/- 10 to 3 bar).
• Note: under 1.5 bar pressure, time flow will fall. In this case the use of a DP grid is recommended
to limit this reduction of time flow.
Dual control panels
• Open and close non-time flow valves with ¼ turn.
• Temperature selection on the thermostatic mixer.
EN
• Electrical supply: 100-240V / 50-60 Hz class II SELV (separated from earth) electrical supply.
• The installation must conform to local Electrical Regulations/Standards and must be installed
by a competent, qualified electrician.
• If the supply cable is damaged, the installer must replace it.
• Secure the cables in place with a fixed router e.g. a rigid sheath or cable holder.
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.
CHEMICAL AND THERMAL SHOCKS
• This product has been designed to withstand both thermal and chemical shocks in line with current
regulations.
INSTALLATION
• Pressure: 1 bar (100 kPa) at 5 bar (500 kPa), recommended: 3 bar (300 kPa).
• Pressure difference at inlets EC/EF: 1 bar max.
• HW supply temperature: 55-85°C (recommended difference between hot and cold water
is 50°C minimum).
• CW supply temperature: 5-20°C.

TECHNICAL FEATURES
Shower panel with individual thermostatic mixer for mixed water distribution.
• Temperature stability: ±1.5°C between 36°C and 41°C
• Preset at 38°C (MW) in factory (turn limiter anti-clockwise), with a 50°C temperature difference
between cold and hot water.
• Temperature can be adjusted from cold up to 38°C. First temperature limiter set at 38°C,
second limiter at 41°C by pressing the button on the control

.
• Safety: hot water shut-off in the event of cold water failure and vice versa.
• Thermal safety is active if the temperature difference between hot water and cold water is above 15°C
and if the mixed water is not above 41°C.
• 6 lpm flow rate with fixed shower head (±1) at 3 bar (300 kPA).
• Thermal shocks can be carried out at the hot water system temperature without removing the control:
- Press the red button using a pointy object Ø 4mm max.
The temperature limiter at 41°C will unblock.
- ½ turn anti-clockwise in order to achieve the maximum temperature supplied by the network.
• The cold water can now be cut without it cutting off the hot water.
•
Once the thermal shock has been carried out, do not forget to return to the starting
position by turning the control clockwise until the red button clicks (in order to respect
the safety of the hot water limiter).
TEMPERATURE SETTING
Our mixers are pre-set in factory at 3 bar (300 kPa) with equal hot and cold water pressures and a hot
water pressure of 65°C ±5°C and cold water 15°C ±5°C.
If the conditions of use are different, the mixed water temperature can differ from the temperature pre-set
in factory. You should reposition the control at the corresponding temperature (
fig. D, E and F
).
