Filter Replacement
Exposed Models
1. Isolate the water supplies.
2.
Turn on the flow control knob to relieve water
pressure and to drain any residual water.
3. Unscrew the shower hose or rigid riser from
the mixer outlet.
4. Using a suitably sized wrench loosen both
compression nuts.
5. Using a 2.5 mm hexagonal key (supplied)
unscrew the grubscrew securing the mixer to
the backplate.
6. Remove the mixer.
7. The filters are retained in the elbow inlet,
remove them and inspect for debris blockage.
Clean each of the filters under a jet of water to
remove any lodged particles.

FAULT DIAGNOSIS
Symptom:
•
Only hot or cold water from the mixer outlet.
•
Outlet temperature too hot / too cold.
Cause Rectification:
•
Inlets reversed (hot supply to cold supply).
Refer to section:
‘Reversed Inlet Supplies’
.
•
No hot water reaching mixer.
•
Check the filters for any blockage refer to
section
‘User Maintenance’.
•
Installation conditions outside operating
parameters, refer to sections:
‘Specifications’
and
‘Commissioning’
.
•
If the temperature is too cold and you have
a combination type boiler it may not be
producing sufficiently hot water at desired
flow rate (refer to
‘Specifications’
). Fit flow
regulator (supplied) to shower valve outlet.
For more information contact Mira Showers
or visit the website.
—————————————
Symptom:
•
Fluctuating or reduced flow rate.
Cause Rectification:
•
Check the showerhead, hose and filters for
any blockage.
•
Make sure that the maintained inlet pressures
are nominally balanced and sufficient, refer to
section:
‘Specifications’
.
•
Make sure that the inlet temperature
differentials are sufficient, refer to section:
‘Specifications’
.
•
Air lock or partial blockage in the pipework.
•
Flow regulator fitted incorrectly.
•
Low flow causing combination boiler to cycle.
Operate at preset maximum flow.
•
Mira Minilite Eco models only - flow regulator
causing combination boiler to cycle. Replace
6 L/Min flow regulator (fitted) with 8 L/Min flow
regulator (supplied).
—————————————
Symptom:
•
Water leaking from the showerhead.
Cause Rectification:
•
Normal for a short period after shut off.
•
Check that the pressures are not in excess of
the specifications for the product.
•
Renew the thermostatic cartridge.
