Servicing & Cleaning - Delabie PREMIX Nano Handbuch

• It is possible to change the mixed
EN
water temperature by:
- Removing the cap
- Turning the screw
clockwise to reduce the temperature
and anti-clockwise to increase the temperature.
- Once the desired temperature has been
achieved, replace the marker
THERMAL SHOCK (fig. C)
• It is possible to undertake a thermal chock at
the temperature of the hot water in the system.
- Remove the cap
- Turning the screw
clockwise to reduce the temperature
and anti-clockwise to increase the temperature
(2-3 turns).
- Once the thermal shock is complete,
re-tighten the screw the same number
of turns (2-3 turns).
REMEMBER
• Our valves must be installed by professional
installers in accordance with current regulations
and recommendations in your country and
the specifications of the fluid engineer.
• Sizing the pipes correctly will avoid problems
of flow rate, pressure loss and water hammer
(see calculation table in our brochure and online
at www.delabie.com).
• Protect the installation with filters, water
hammer absorbers and pressure reducers to reduce
the frequency of maintenance (recommended
pressure from 1 to 5 bars maximum).
• Install stopcocks close to the valve to facilitate
maintenance.
• The pipe work, stopcocks, bib taps and all
sanitary fittings should be checked at least once
a year, and more frequently if necessary.
SERVICING & CLEANING
• Cleaning chrome:
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.

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:
1. Non-return valves, filters and inter-changeable
cartridge: de-scale and replace worn
or damaged parts.
2. Mixing chamber: de-scale.
If the PREMIX is not mixing correctly (fig. D):
• 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 filters
Replace if necessary.
• Check the non-return valves
Replace if necessary.
• To remove the mechanism:
- Remove the cap
- Unscrew the screw
- Remove the thermostatic element (3),
the shuttle (4) and the spring (5) 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
the maximum point, and open the hot
and cold water supply.
