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 Response Adjustable range of flexible and rigid shower fittings are precision
engineered to give a satisfactory shower over a range of pressures. The fittings are
suitable for pressures up to 5.0 bar (ev and biv) or 3.0 bar (bir), and pressures down
to 0.06 bar. The adjustable handset is supplied with a low capacity spray plate fitted.
A high capacity spray plate assembly is also supplied with the Excel shower control
and is available upon request for other shower controls.
Shower fittings covered by this guide:
Mira Response Exposed Variable Shower Fittings (ev)
An adjustable spray handset with three different spray actions (start, force, soothe) and
an economy setting*, supplied complete with flexible hose, adjustable clamp bracket
assembly, slide bar and supports, soap dish and hose retaining ring. Suitable for
connection to surface mounted shower controls only. Available in white, white/chrome,
white/light golden or all chrome finish.
Mira Response Flex Shower Fittings
Offering the same features as the Response ev, in addition a separate wall mounted
handset holder is supplied. Suitable for connection to surface mounted shower controls
only. Available in white/chrome finish.
Mira Response Built-in Variable Shower Fittings (biv)
Offering the same features as the Response ev, but suitable for connection to
concealed pipework supplies only. Available in white, white/chrome, white/light golden
or all chrome finish.
Mira Response Built-in Rigid Shower Fittings (bir)
An adjustable spray head with three different spray actions (start, force, soothe) and
an economy setting*, suitable for connection to concealed pipework supplies only.
Available in white or all chrome finish.
* The economy setting reduces the water flow to give economical use of water, whilst
still giving an adequate shower performance. This setting performs best with most
gravity, pumped, and mains pressure unvented systems. On electric showers and
some combination boiler systems the economy setting will have no effect, and will
give the same spray action as the start setting.
If you experience any difficulty with the installation or operation of your new
shower fitting, then please refer to Section 10. "Fault Diagnosis", before
contacting Kohler Mira Limited. Our telephone and fax numbers can be found
on the back cover of this guide.

1.1. Maximum maintained pressure 5.0 bar. Maintained pressures above this range
could result in excessive spray forces and result in possible damage to the
product.
For bir fittings
1.2. Maximum maintained pressure 3.0 bar. Maintained pressures above this range
could result in excessive spray forces and result in possible damage to the
product.

Installation Requirements
1. Plumbing
Read the section “Important Safety Information” first.
1.1. Supply pipework MUST be flushed to clear debris before connecting the
appliance.
1.2. A hose retaining ring is supplied to prevent the handset from dropping below
the spill-over level of the bath or shower, which could lead to contamination
from backsiphonage. The supplied hose retaining ring should meet the great
majority of user requirements for shower installations with flexible outlet fittings.
However, there will be occasions when the hose retaining ring will not provide
a suitable solution. In these instances an outlet double checkvalve, e.g. the
Mira DCV-H, must be fitted. The inclusion of the Mira DCV-H will increase the
required supply pressure typically by 0.1 bar.
1.3. Avoid layouts where the shower hose will be sharply kinked. This may reduce
the life of the hose.
1.4. Do not fit any form of flow control in the outlet pipework if the shower fitting is
installed in conjunction with a product that requires the fitting to act as a vent
(e.g. an electric shower).
1.5. Do not use excessive force when making connections.
1.6. Do not install the product in a position where it could become frozen.
1.7. For a gravity fed shower installation, the minimum pressure at the handset is
0.06 bar. To generate the minimum pressure and accommodate the pressure
loss in the pipes and shower control, a head of water of 1.0 metre is required
on a typical correct installation.
For a pump installation the minimum acceptable vertical distance between
the base of the cold water storage cistern and the shower head to operate the
pump’s flow switches, is typically 0.6 m (600 mm).
1.8. The shower fitting is connected to the bottom outlet of the shower control or
right angled connector assembly as appropriate.
1.9. When installing the shower fitting into a shower cubicle, it is best positioned to
spray across the cubicle rather than towards the opening.
10
1.10.For ev and biv products the maintained water pressure at the handset should
not exceed 5.0 bar. Maintained pressures above 5.0 bar at the shower head,
could result in excessive spray forces and possible product damage.
1.11. For bir products the maintained water pressure at the spray should not exceed
3.0 bar. Maintained pressures above 3.0 bar at the shower head, could result
in excessive spray forces and possible product damage.
1.12.Layout and sizing of pipework be such that when other services are used,
pressures do not fall below the recommended minimum for that fitting as this
will cause the spray pattern to collapse.
1.13.Perceived sound levels of the handset, pump (if fitted) and spray impingement,
will be affected by the spray pattern selected and flow rates.
2. Spray plate assembly - selection
2.1. All shower fittings have the low capacity spray plate assembly installed as
standard. The low capacity spray plate assembly is suitable for the pressures
generated by a head of water between 0.6 and 5.0 Metres. For the higher
pressures generated by a greater head install the high capacity spray plate
assembly to allow more flow, refer to Section 9, Maintenance: 2. Spray
plate assembly - removal and installation. The high capacity spray plate
assembly is supplied in addition to the low capacity spray plate assembly with
the Excel only. It is available upon request for other Mira shower controls.
2.2. The high capacity spray plate assembly is recommended for gas water heaters
that require a higher flow rate to operate correctly.
2.3. Identification - Both spray plate assemblies have an identification letter in the
bottom of the centre recess in the back face. The 'L' signifies a low capacity
spray plate assembly and the 'H' signifies the high capacity version.

Installation
Mira Response ev and Flex
1. Solid, dry-lined, stud partition, shower cubicle or laminated
panel walls
Read the section “Installation Requirements” first.
The slide bar should be fixed to the wall to one side of the product and at a convenient
height for all the family. It should be positioned so that it discharges down the centre
line of the bath, or across the opening of a shower cubicle and should be directed away
from the shower control.
1.1. Decide on a suitable location for the
slide bar avoiding buried cables and
pipes. The position of the shower
control and the shower fittings must
provide a minimum gap of 25 mm
between the spill-over level and
the handset. This is to prevent
backsiphonage. Alternatively the
Mira outlet double check valve
(DCV-H) can be fitted and is
available as an accessory.
1.2. For solid walls drill two 6.0 mm
diameter holes at 600 mm centres
and Insert the wall plugs.
12
Note! Special consideration
should be given to the fixing
arrangements when installing on to
a dry lined, stud partition, shower
cubicle or laminated panel wall
structures. Installers may wish to
obtain alternative proprietary cavity
fixing, or choose other options,
however, these methods of fixing
are beyond the scope of this guide.

and commissioning are satisfactory and in accordance with
the instructions in this manual. We are on hand to offer you
or your installer any advice you may need.
Should this not resolve the difficulty, simply contact our
Customer Services Team who will give every assistance
and, if necessary, arrange for our service engineer to
visit. If the performance of your shower declines, consult
this manual to see whether simple home maintenance is
required. Please call our Customer Services Team to talk
the difficulty through, request a service under guarantee
if applicable, or take advantage of our comprehensive
After-Sales service.
