• IMPORTANT: Once the thermal shock treatment is complete, reset the temperature
to reactivate the maximum hot water security setting.
- Check that the water supply and pressure are in the correct range.
- Re-commission the mixing valve ensuring the temperature is in the correct range.
- Replace the cap and check that the temperature does not exceed 41°C.
• The cold water can be isolated without having to shut-off the hot water.
• ALWAYS carry out a cold water fail-safe check after any adjustment.
• The SECURITHERM mixer is designed to withstand thermal shocks up to 85°C.
MAINTENANCE
• Check the calibration at least twice a year (Fig. A).
• We recommend checking the anti-scalding failsafe twice a year 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:
- Interchangeable cartridge: descale internal parts, and replace any worn or damaged components.
- Remove the cartridge by unscrewing the chamber anti-clockwise by hand (Fig. C).
- Mixing chamber: descale.
- Check the stainless steel filters and clean if necessary.
• In the event of malfunction during checks: clean the mechanisms and descale. Change any worn parts
if necessary.
MAINTENANCE & CLEANING
• Cleaning chrome, aluminium 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 valve 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.
