INTRODUCTION
Thank you for purchasing a quality Mira product. To
enjoy the full potential of your new product, please
take time to read this guide thoroughly, having
done so, keep it handy for future reference.
The Mira Moto and Mira Minilite are thermostatic
mixers with a single control lever for on/off and
temperature control. They are supplied complete
with Mira L14A Shower Fittings.
The Mira Pace and Mira Miniduo are thermostatic
mixers with separate flow and temperature
controls. They are supplied complete with Mira
L98B Shower Fittings.
The thermostatic mixers incorporate a wax
capsule temperature sensing unit, which provides
an almost immediate response to changes in
pressures or temperature of the incoming water
supplies to maintain the selected temperature. An
adjustable maximum temperature stop is provided
which limits the temperature to a safe level.
Inlet lters are tted to protect the thermostatic
cartridge.

SPECIFICATIONS
Pressures
Max Static Pressure: 10 Bar.
•
Max Maintained Pressure: 5 Bar.
•
Min Maintained Pressure (Gravity System):
•
0.1 Bar. (0.1 bar = 1 Metre head from cold
tank base to shower handset outlet).
Note! For gravity fed / other low pressure
systems (0.5 bar or below) remove the ow
regulator(s).
For optimum performance supplies should be
•
nominally equal.
Temperatures
Factory Pre-set (Blend) Shower: 43°C.
•
Optimum Thermostatic Control Range: 35°C
•
to 43°C (achieved with supplies of 15°C cold,
65°C hot and nominally equal pressures).
Recommended Hot Supply: 60°C to 65°C
•
Note! The mixi ng va lve can ope rate at
higher temperatures for short periods without
damage, however this could detrimentally
affect thermostatic performance. For safety
and performance reasons it is recommended
that the maximum hot water temperature is
limited to 65°C.
Cold Water Range: up to 25°C.
•
Minimum Recommended Differential between
•
Hot Supply and Outlet Temperature: 12°C.
Flow Regulators
Site conditions and thermostatic mixer model will
determine the ow regulator requirements.
For gravity systems (0.5 bar or below) remove the
inlet and outlet ow regulators (where tted).

INSTALLATION
Suitable Plumbing Systems
Gravity Fed:
The thermostatic mixer must be fed from a cold
water cistern (usually tted in the loft space) and
a hot water cylinder (usually tted in the airing
cupboard) providing nominally equal pressures.
Mains Pressurised Instantaneous Hot Water
System (Combination Boiler):
The thermostatic mixer can be installed with
systems of this type with balanced pressures.
(Recommended Minimum Maintained Pressure:
1.0 Bar).
Unvented Mains Pressure System:
The thermostatic mixer can be installed with an
unvented, stored hot water system.
6. Decide on a suitable position for the Mixer.
The position of the Mixer and the Shower
Fittings must provide a minimum gap of 25 mm
between the spill-over level of the shower
tray/bath and the handset (refer to illustration).
This is to prevent back-siphonage. For further
information on the installation of your Shower
Fittings, refer to the Fittings Installation and
User Guide.
Note! Only use Shower Fittings recommended
by the manufacturer or supplier.
Pumped System:
The thermostatic mixer can be installed with an
inlet pump (twin impeller). The pump must be
installed in a suitable location and in accordance
with its instructions.
General
Installation must be carried out in accordance
with these instructions, and must be conducted by
designated, qualied and competent personnel.
The installation must comply with the “Water
Supply Regulations 1999 (Water Fittings)” or any
particular regulations and practices, specied by
the local water company or water undertakers.
Note! Make sure that all site re qui rements
correspond to the information given in section:
‘Specications’.
1. The Mixer must not be installed in an area
where it may freeze.
2. For stud partitions alternative xings may be
required.
3. Isolating valves must be installed close to the
Mixer for ease of maintenance.
4. Pipework must be rigidly supported and avoid
any strain on the connections.
5. Pipework dead-legs should be kept to a
minimum.

Exposed Thermostatic Mixers
For Built-in Thermostatic Mixers go to section:
‘Installation, Built-in Thermostatic Mixers’.
Installing the Thermostatic Mixer
1. The thermostatic mixer can be installed with
rear, rising or falling supply inlets. Decide
on the most appropriate method for your
installation, and if necessary, loosen the
grubscrews and rotate the inlet elbows to
suit.
Important! Make sure that the elbows are
pushed fully onto the mixer before tightening
the grubscrews.
Important! A ow regulator is tted inside the
cold inlet elbow (some models). This can be
removed for gravity fed / other low pressure
systems (0.5 bar or below), refer to section:
‘Specications,FlowRegulators’.
39 mm
3. For solid walls drill the holes for the backplate
with a 6 mm drill and insert the wall plugs
(supplied). For other types of wall structure
alter native fixings may be required (not
supplied).
Wall Plug
2. Use the installation template to mark the
positions of the holes for the backplate and
the pipe centres.
For rising or falling supplies the pipe positions
should be set 39 mm from the centre of pipe
to the nished wall at 110 mm centres.
Note! If replacing an existing installation
with pipework centres between 133 mm and
153 mm a universal retrot accessory kit is
available, refer to section: ‘Accessories’.
6 mm Drill
4. For Rear Entry Supplies Only:
a) Drill the holes for the supply pipes at
110 mm centres.
Note! Recess the inlet holes Ø19 mm x
2 mm deep to allow for the concealing
plates.
5. Fit the supply pipework: Hot - Left, Cold
- Right. The inlet pipework should extend
23 mm from the nished wall surface.
Note! If it is not poss ib le to ins tall the
mixer with this pipework conguration follow
instruction 6.
