Summary
Mira 1869.043 is a thermostatic cartridge assembly for the Minilite built-in shower valve platform. It is the temperature control cartridge used inside the concealed shower control unit and is supplied as the cartridge assembly rather than a loose thermostatic element.
This part restores thermostatic blending and outlet temperature control. Typical fault symptoms can include incorrect temperature, only hot or only cold water reaching the outlet, unstable temperature control, or continued water leaking from the shower head after shut-off beyond the brief normal drain-down period.
Technical Details
- For the covered built-in valve platform the inlet connection is 15 mm male compression.
- Outlet connection is 15 mm male compression on Mira Minilite BIR, Mira Minilite Built-In, and Mira Moto BIR versions.
- Outlet connection is 1/2 inch BSP flat face to flexible hose on Mira Minilite BIV and Mira Moto BIV versions.
- Platform pressure and temperature limits are 10 bar maximum static pressure, 5 bar maximum maintained pressure, 0.1 bar minimum maintained pressure, hot supply 60C to 65C, cold supply 2C to 25C, with a minimum 12C difference between hot supply and outlet temperature.
- The installation guide for the covered valve platform shows overall dimensions of 175 mm width and 114 mm depth, with a 54 to 65 mm build depth and a 48 to 59 mm trim projection range.
- If the hot inlet is on the right-hand side the cartridge must be rotated 180 degrees and the chrome trim must also be rotated 180 degrees before refitting.
