• 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 mixer/tap/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.
