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).
