Calibration

The Mio shower valve has a factory set outlet temperature of 38˚C via the security setting. 
This is based on a balanced supply pressure and a stable hot water inlet temperature of 65˚C.

However, the calibration point 

MUST

be checked and re-set as necessary to suit site conditions.

Care must be taken when re-calibrating the valve as 

INCORRECT CALIBRATION CAN CAUSE

INJURY.

  •   Remove the temperature control knob (15) by pulling away from the shower valve and the 

      temperature stop ring (12).

• Fully open the flow control and allow the outlet temperature to stabilise.

• Temporarily refit the control knob (15) and using a digital thermometer it is possible to increase

or reduce the mixed water outlet temperature until 38˚C is re-established, by slowly rotating 
the control knob.

• Remove the control knob (15) and refit the temperature stop ring (12) onto the splined section

of the cartridge. The red dot on the temperature stop ring must align with the temperature 
position symbol on the temperature control concealing sleeve (10).

• Refit the temperature control knob in the reverse order ensuring that 38˚C on the control knob

is in line with the temperature position symbol (10). 

PLEASE NOTE THAT ONCE CALIBRATED, THE SECURITY SETTING WILL ONLY BE 38˚C 

UNDER THE SUPPLY CONDITIONS USED FOR CALIBRATION. 

Cartridge Replacement

  •  

Isolate both the hot and cold water supplies

  •   Remove the temperature control knob (15) by pulling away from the shower valve, the gear 

      drive (13) and the temperature stop ring (12).

  •   Using a suitable spanner unscrew the cartridge (3). 

  •   Replace with a new cartridge.

  •   The shower valve must be re-calibrated after fitting the new cartridge following the procedure

      above.

  •   Refit the temperature stop ring (12) onto the splined section of the cartridge. The red dot on the

      temperature stop ring must align with the temperature position symbol on the temperature 
      control concealing sleeve (10).

  •   Refit the gear drive (13).

  •   Refit the temperature control knob in the reverse order ensuring that 38˚C on the control knob

      is in line with the temperature position symbol (10).
