If you experience any difficulty with the
installation or operation of your new shower
fi ttings, please refer to ‘Fault Diagnosis’,
before contacting Kohler Mira Ltd. Our contact
details can be found on the back cover of
this guide.
Thank you for purchasing a quality Mira product. T o
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.
Mira ECO adjustable shower fi ttings are designed
to give a satisfactory shower over a range
of pressures. These fittings are suitable for
pressures between 0.5 and 5.0 bar and are
available in chrome or white fi nishes.
General
1. Make sure that the shower fi ttings are installed
by a competent installer.
2. Installations must comply with Water Regulations
(Bye-Laws, Scotland), and any other Local
Regulations and Building Regulations in force
at the time of installation.
3. Before installation carefully inspect the new
fi xture for any signs of damage.
4. The shower fi ttings should be positioned at a
convenient height for all the family. Position
the fi ttings to spray across rather then towards
the opening of the cubicle and also away from
the shower control. Avoid layouts where the
shower hose will be sharply kinked. This may
reduce the life of the hose.
5. A hose retaining ring is supplied to prevent
the showerhead 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 fl exible outlet fi ttings.
However, there will be occasions when the
hose retaining ring will not provide a suitable
solution. In these instances an outlet double
check valve, e.g. the Mira DCV-H, must be
fi tted. The inclusion of the Mira DCV-H will
increase the required supply pressure typically
by 0.1 bar.
6. Special consideration should be given to the
fi xing arrangements when installing onto a
dry lined, stud partition, shower cubicle or
laminated panel wall structures. Installers may
wish to obtain alternative proprietary cavity
fi xings, or choose other options, however,
these methods of fi xing are beyond the scope
of this guide.

INSTALLATION
RAC Assembly
The RAC assembly is supplied with built-in mixer
showers only.
1. Before the RAC assembly can be fi tted you
must have fi rst installed your built-in shower
control and have connected the inlet and
outlet pipework. Refer to your shower control
installation and user guide.
Important! Make sure that the outlet pipework
protrudes through a Ø25 mm hole in the wall
or stud partition by approximately 40 mm.
Note! For stud partition installations where
access to the rear of the partition is possible,
fi t the RAC wallplate over the outlet pipework
on the inside of the partition.
For stud partition installations where access
to the rear of the wall is not possible, follow
instructions for solid wall installations, making
sure that suitable wall fi xings (not supplied) are
used to secure the wallplate to the outside of
the stud partition.
RAC Wallplate
(shown fi tted for rear
access stud partitions only)
4. For solid wall installations or stud partition
installations without rear access go to
instruction 9.
For stud partition installations with access
to the rear of the partition continue with
instruction 5.
5. Finish the wall (e.g. tiles).
Important! Refer to your shower control
installation and user guide.
Caution! Make sure that the fi nished wall
is within the maximum and minimum limits
and to an even depth (no greater than 2 mm
variation).
6. Place the RAC backplate over the outlet pipe
with the arrow pointing up. The screw holes
should be at 45° to the horizontal.
7. Mark the positions of the two RAC backplate
fi xing holes and drill the two 5.5 mm holes.
Caution! Make sure that you do not drill into
pipework in the wall.
8. Hold the RAC wallplate in position on the rear
of the partition, insert the two backplate screws
and secure the RAC backplate to the wallplate.
Make sure that the foam seal abuts the fi nished
wall surface. Go to instruction 17.

to the outside of the backplate nut. Press
the elbow onto the backplate, make sure
that the clips on the elbow engage with the
backplate.
19. Press the shroud over the elbow, make
sure that it engages with the lugs on the
backplate.
11. Remove the assembly from the wall and
separate the backplate from the wallplate.
12. For solid walls drill two 6 mm holes for the
wall plugs. For other types of wall structure
alternative fixings may be required (not
supplied). If necessary, make a recess 6 mm
deep to accept the wallplate for fl ush fi tting of
the outlet to the wall surface.
Caution! Make sure that you do not drill into
pipework in the wall.
13. Fit the two wall plugs supplied and secure
the wallplate to the wall with the two wallplate
screws.
14. Make sure that there is clearance behind the
wallplate and temporarily fi t the two backplate
screws into the wallplate. This will prevent
the fi xing holes from becoming blocked with
plaster or grout.
15. Finish the wall, e.g. tiles. then remove the two
backplate screws.
Important! Refer to your shower control
installation and user guide.
Caution! Make sure that the fi nished wall

Fault Diagnosis
Symptom:
•
No flow or low flow rate from shower
fi ttings.
Cause / Rectifi cation:
•
Spray plate blocked, clean or renew.
Make sure that the hose is not blocked or •
twisted.
Head of water below minimum required (Min
•
supply pressure 0.5 Bar)
Problem with the shower control, refer to your
•
shower control installation and user guide.
—————————————
Cleaning
Many household cleaners contain abrasives and
chemical substances, and should not be used for
cleaning plated or plastic fi ttings.
These fi nishes should be cleaned with a mild
washing up detergent or soap solution, and then
wiped dry using a soft cloth.
Use your thumb or a soft cloth to wipe any
limescale from the soft nozzles and the front
surface of the showerhead spray plate.
Important! The spray plate must be regularly
cleaned to make sure that the showerhead does
not become blocked.
Symptom:
•
Drip from the showerhead.
Cause / Rectifi cation:
•
A small amount of water may be retained in
the showerhead after the shower control has
been turned off. This is quite normal, changing
the angle of the showerhead may vary the
draining time.
Problem with the shower control, refer to your
•
shower control installation and user guide.
—————————————
Symptom:
•
Shower temperature changes when spray
action is adjusted.
Cause / Rectifi cation:
•
Adjusting the spray action changes the fl ow of
water. This may affect some shower controls
and plumbing installations. To minimise
the effect make sure that the spray plate is
clean.
Spray Plate Assembly - Internal
1. Remove the spray plate assembly.
2. Clean all the components with a stiff brush.
If necessary use a plastic kettle descalent
in accordance with the manufacturer's
instructions. Flush thoroughly with water
before the shower is used.
3. If necessary replace the 'O' seals. Refer to
section: Spare Parts.
4. Refi t the components in reverse order . Make
sure that the 'O' seals and the inner and outer
nozzle retaining rings are fi tted correctly.
