THERMAL SHOCK (Fig. E)
SECURITHERM is designed to withstand the thermal and chemical shocks recommended
•
in current regulations.
It is possible to activate a thermal shock at the temperature of the hot water in the system without
•
removing the control knob:
- Press on the red button  using a pointed tool no bigger than Ø 4mm , (the 41°C temperature
limiter will override).
- Turn through 180° clockwise to allow the water to flow at the supply temperature in the system.
The cold water can be isolated without the hot water shutting off.
•
Once the thermal shock is complete, do not forget to return to the original setting by turning
•
the control knob anti-clockwise until you hear a «click» for the first temperature limiter
(to maintain the Hot Water failsafe).
MAINTENANCE
Check the calibration at least twice a year (Fig. D).
•
We recommend checking the anti-scalding failsafe every two months in hard water areas or if the water
•
is heavily charged. Shut off the cold water and ensure that the hot water shuts off in less than 2 seconds.
To maximise the reliability of thermostatic mixing valves over time, and to reduce the risks associated
•
with Legionella, DELABIE recommends an annual check of the following items:
1. Non-return valves and filters: descale and replace any worn or damaged components.
2. Interchangeable cartridge: descale internal parts and replace any seals that are worn
or damaged.
3. Mixing chamber: de-scale.
In the event of malfunction during checks: clean the mechanisms and descale.
•
Change any worn parts if necessary.
MAINTENANCE & CLEANING
Cleaning chrome and stainless steel: do not use abrasive, chlorine or any other acid-based
•
cleaning products. Clean with mild soapy water using a cloth or a sponge.
Frost protection: drain the pipes and operate the mixer several times to drain any remaining water.
•
In the event of prolonged exposure to frost, we recommend taking the mechanisms apart and storing
them indoors.
* For 15mm compression fittings or hard copper tail options with non-return valves,
please contact Technical Support (see below).
