Important Safety Information
WARNING ! This shower can deliver scalding temperatures. For
continued safe operation, follow all instructions, warnings and
cautions contained in this guide and on or inside the shower.
Periodic maintenance may be required to keep the product in
good working order.
The function of a thermostatic mixing valve is to deliver water
consistently at a safe temperature. In keeping with every other
mechanism, it cannot be considered as functionally infallible and
as such, cannot totally replace a supervisor’s vigilance where that
is necessary. Provided it is installed, commissioned, operated and
maintained within manufacturers recommendations, the risk of
failure, if not eliminated, is reduced to the minimum achievable.
PLEASE OBSERVE THE FOLLOWING TO REDUCE THE RISK
OF INJURY:

Specications
For Type 2 Valves, the supply conditions specied in the TMV2 Requirements Manual take
precedence over the operating parameters which follow.
Pressures
• Max Static Pressure: 10 Bar.
• Max Maintained Pressure: 5 Bar.
• Min Maintained Pressure (Gravity System): 0.1 Bar (0.5 Bar for models with Eco
Showerhead). (0.1 bar = 1 Metre head from cold tank base to showerhead outlet).
Note: For gravity fed or other low pressure systems (0.5 bar or below) do not t the outlet
ow regulator (where applicable).
• For optimum performance supplies should be nominally equal.
Temperatures
• Factory Pre-set (Blend) Shower: 43° C.
• Optimum Thermostatic Control Range: 35° C to 45° 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 mixing valve can operate at higher
temperatures for short periods without damage, however this could detrimentally a󰀨ect
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 Di󰀨erential between Hot Supply and Outlet Temperature: 12° C.
Thermostatic Shut-down
• For safety and comfort the thermostat will shut o󰀨 the mixing valve within 2 Seconds if
either supply fails (achieved only if the blend temperature has a minimum di󰀨erential of
12° C from either supply temperature).
Connections
• Inlets: Mixing valve ONLY accepts 15mm OD copper pipe.
IMPORTANT This product is not suitable for use with any other pipe sizes
• Outlet: ½” BSP Flat Face
• Standard connections are:
• Hot - Left, Cold - Right
• Outlet - Bottom
WARNING! This product does not allow for reversed inlets and will deliver dangerously
unstable temperatures if tted incorrectly.
Suitable Plumbing Installations
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).

8
1285246-W2-D
Unvented Mains Pressure System:
The thermostatic mixer can be installed with an unvented, stored hot water system.
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.
Installation
General
1. Installation of the shower must be carried out in accordance with these instructions
by qualied, competent personnel.
2. The plumbing installation must comply with all national or local water regulations
and all relevant building regulations, or any particular regulation or practice
specied by the local water supply company.
3. Make sure all pressures and temperatures comply with the requirements of the
shower. See ‘Specications’. For Type 2 Valves, refer to supply conditions given
in the TMV2 Requirements Manual (this is available to view or download from
our website www.mirashowers.com).
4. Full bore/non restrictive servicing valves must be tted in a readily accessible
position adjacent to the shower to facilitate maintenance of the shower.
DO NOT use a valve with a loose washer plate (jumper) as this can lead to a
build up of static pressure.
5. DO NOT apply excessive force to plumbing connections; always provide
mechanical support when making plumbing connections. Any soldered joints
should be made before connecting the shower.
6. Pipework dead-legs should be kept to a minimum.
7. DO NOT install the shower unit in a position where access for maintenance is
restricted.
8. The shower must be tted to a waterproof, at and even wall surface. The two
screws and wall plugs supplied are suitable for most solid wall installations. Alternative
xing screws for panel structures are not supplied. Use both xing points to secure
the shower, be sure to use xings appropriate for the chosen wall structure.
9. When pipework enters the product from the rear through a hole in the wall,
provision must be made to prevent water ingress back into the wall structure.
10.Position the shower unit where the controls are at a convenient height for the
user. Position the showerhead so that the water sprays in line with the bath or
across the opening of a shower cubicle. The installation must not cause the
shower hose to be kinked during normal use.
11. The water supplies to this product should be isolated if the product is not to be
used for a long period of time. If the product or pipework is at risk of freezing
during this period they should also be drained of water.

91285246-W2-D
Note ! There will be occasions when the hose retaining ring will not provide a suitable solution
for Fluid Category 3 installations. In these instances an outlet double checkvalve must be
tted, this will increase the required supply pressure typically by 10 kPa (0.1 bar). Double
checkvalves tted in the inlet supply to the appliance cause a pressure build up, which
a󰀨ects the maximum static inlet pressure for the appliance and must not be tted. For Fluid
Category 5, double checkvalves are not suitable.
12. The position of the shower and shower ttings must provide a minimum air
gap of 25 mm between the showerhead and the spill over level of any bath,
shower tray or basin. There must be a minimum distance of 30 mm between
the showerhead and the spill over lever of any toilet, bidet or other appliance
with a Fluid Category 5 backow risk.

Installation
Critical! The installation area must be carefully prepared and all tiles cut or
drilled accurately for a successful installation.
Note: This product DOES NOT allow for reversed inlets and will deliver dangerously
unstable temperatures if tted incorrectly. If the tile cutting area exceeds the
boundaries listed (step 6) below, the wall plate may not conceal drilled holes.
The shower ttings should be positioned at a convenient height for all the family.
Position the 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.
Shower Positioning
To enable sufficient
clearance the valve must
be a minimum 1.1 m
from the ceiling.

1. Pipework must be at 50 mm centres, level
and perpendicular to the finished wall
surface (see g 1).
2. It is recommended that the pipework is
secure but not rigidly xed at this stage,
in case of further adjustment when the
retaining wallplate is tted.
3. Only use Ø15 mm copper pipe for
connection to the valve.
DO NOT use any other pipe sizes.
4. Ensure you have enough pipework through
the wall to allow it to be cut to the specied
length when wall is nished (refer to the
instruction on page 10).
5. The drill holes for the central tting of the
wallplate screws must be into brick, wooden
noggin or similar sound wall structure.
We recommend the sound wall structure
should extend to an area approximately 30
mm around the pipe centres (see g 2).
6. This product does not have a shroud,
accurate drilling of the tiles is essential to
allow the wallplate to prevent water ingress

Shroud over the pipe stubs. This will prevent
damage to the to the pipe surface from tiling
and grout etc and assist with the correct pipe
centres and alignment.
Remove the pipe shroud and trim the pipe
stubs to 23 mm +/-5 mm from the wall
surface DO NOT use a hacksaw as the
sharp edges may damage the seals in the
mixer valve. Note: De-burr the pipework if
necessary.

Fit One Flow Regulator Per Outlet!
We highly recommend the tting of a ow regulator for optimum temperature control and
showering experience.
For maintained (running) water pressure greater than 0.5 bar, installing a ow regulator can
help to reduce:
• Excessive shower force
• Noise due to high or unequal water pressure
• Unstable supply temperature
• Cooler outlet temperatures due to the colder seasons
12 L/min (red) to reduce excessive shower force and stabilise temperatures.
6 L/min (black) for eco water conservation while showering.
Note: In some circumstances such as when the incoming cold water temperature supply is
very low to a combination boiler a 9 l/min ow regulator may be required to improve the hot
water performance. Contact Mira Customer Service.
Note: The 6 l/min ow regulator may a󰀨ect the performance of some combination boilers
while the shower is running. Check with the boiler’s manufacturer before tting.
DO NOT t a ow regulator if the maintained (running) water pressure is less than 0.5 bar or
the shower force is too low.

Before using the shower, the maximum temperature must be checked to make sure that it is
at a safe level. It has been preset to a safe showering temperature under ideal conditions at
the factory, appropriate for most systems. However, site conditions and personal preference
may make it necessary to reset this temperature.
Note: Make sure that the hot water temperature is at least 55° C and that there is su󰀩cient
supply.
Make sure that all users are familiar with the operation of the shower. This guide is the
property of the homeowner.
Note: For Type 2 installations the maximum temperature is determined by application, refer
to the TMV2 Requirements Manual.
If you experience any di󰀩culty with the operation of your new shower, then please refer to
“Fault Diagnosis”, before contacting our customer services department.
