Maintenance & Cleaning - Delabie PREMIX NANO 732515 Manual De Instrucciones

MAINTENANCE
• Check the calibration and anti-scalding failsafe at least twice a year, (and more frequently
in hard water or heavily charged areas).
• To maximise the reliability of the PREMIX over time, and to reduce the risks associated with Legionella,
we recommend checking the following items at least twice a year:
- Non-return valves, filters and inter-changeable cartridge: de-scale and replace worn or damaged parts.
- Mixing chamber: de-scale.
If the PREMIX is not mixing correctly (Fig. E):
• Make sure the HW/CW pressures are balanced. The pressure difference between the hot
and cold water pressure should be less than 1 bar.
• Check the hot water temperature. The temperature should be more than 55°C.
• Isolate the hot and cold water supply.
• Check that the sealing washers . are correctly sited. Replace if necessary.
• Check the stainless steel filters . Clean if necessary.
• Check the non-return valves . Replace if necessary.
• To remove the mechanism:
- Remove the cap .
- Unscrew the screw  using a 10mm Allen key.
- Remove the thermostatic element , the shuttle  and the spring  gently by hand.
- Clean the shuttle and the thermostatic element.
- Clean the inside of the mixer body .
- Check the 4 O-rings on the shuttle, replace the mechanism, tighten the screw  to the maximum
point, and open the hot and cold water supply.
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 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.
