NB: It is possible to adjust the temperature from 30 - 60°C by removing the control knob and turning
the notched spindle all the way in one direction or the other to achieve the desired temperature.
THERMAL & CHEMICAL SHOCKS
• PREMIX COMPACT is designed to withstand the thermal and chemical shocks recommended
within current regulations.
• To undertake a thermal shock (fig. D):
- Remove the covering cap a using a flat-headed screwdriver.
- Loosen the locking screw b using a Phillips screwdriver.
- Remove the control knob c by hand.
- Turn the notched spindle d ¾-turn to the left.
- Shut off the cold water supply.
- Once the thermal shock is complete, do not forget to re-set the temperature to the initial setting.
- Replace the control knob c.
SERVICING
Check the temperature setting and the anti-scalding safety at least twice a year (depending on the water quality).
To ensure continued reliability of the PREMIX, and to conform with local Anti-Legionella legislation,
we recommend checking the following at least twice a year:
• Non-return valves, filters and replaceable cartridge: de-scale or replace worn or damaged parts.
• Mixing chamber: de-scale.
If the PREMIX is not mixing correctly (fig. E):
• Balance the pressure. The pressure differential between the hot water and the cold water must be less
than 1 bar.
• Check the hot water supply temperature. The temperature should be higher than 55°C
• Shut off the water supply.
• Check that the filters f have been installed correctly. Replace if necessary
• Check the non-return valves e. Replace if necessary.
• The water supply must be connected using nuts with a compacted flange or a flat faced tap connector.
• To remove the mechanism:
- Unscrew the outlet nipple l using a 33mm spanner.
- Remove the spring k.
- Remove the water guide j.
- Remove the thermostatic element and the shuttle i by hand.
• Clean the thermostatic element and the shuttle i.
• Clean the mixer body interior.
• Check the O-ring.
• Replace the mechanism. Turn on the water supply. Always carry out a cold water failsafe check after
dismantling or carrying out maintenance.
MAINTENANCE & 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 mixer/tap 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.
