Maintenance & Cleaning - Delabie PREMIX SECURIT Manual De Instrucciones

CALIBRATION (FIG. D)
The PREMIX is tested at the factory and calibrated to 53°C (hot and cold water pressure = 3 bar).
Once the installation is complete and the pipes have been flushed thoroughly, the mixing valve must be re-calibrated.
• To change the water temperature: remove the screw and then remove the control knob. Lightly turn the control
knob clockwise to reduce the temperature and anti-clockwise to increase.
Important: to prevent the Premix being damaged do not complete a full turn with the rod.
• Replace the control knob with 53° in line with the marker on the body. The mixing valve can be set between 44°C
and 58°C.
• In the event of a sudden loss of cold water supply, re-calibrate the mixing valve.
THERMAL SHOCKS
• To carry out a thermal shock: remove the control knob, turn the rod with notches anti-clockwise with a 3/4 turn,
then shut off the cold water supply.
• After the thermal shock, do not forget to open the cold water and re-calibrate.
MAINTENANCE (FIG. E)
• The following checks should be carried out at least twice per annum (and more frequently
in hard water areas).
• Ensure that the Hot and Cold water supply Temperatures and Pressures are within the ranges
in the System Specification.
• Check the temperature calibration of the thermostatic mixing valve.
• Carry out anti-scalding safety. The anti-scalding safety is active if the temperature difference between
the hot water and the delivery of mixed water is greater than 15°C.
• Check the non-return valves and the filters at the inlets.
Check Annually
• To maximise the reliability of PREMIX valves over time and to reduce the risks associated with Legionella,
we recommend an annual check of the following:
- Non-return valves e and filters f: de-scale and replace worn or damaged parts.
- Inter-changeable cartridges g: de-scale internal pieces and replace worn or damaged parts and washers.
- Mixing chamber h: de-scale.
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 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.
