What affects shower performance?
The shower unit's top priority is to keep the desired water temperature constant.
To maintain this temperature, the shower may have to automatically change the
rate of water fl owing through the unit. Any of the following conditions can cause the
shower to change the fl ow rate (force of the shower) in order to keep the temperature
constant. Most changes are minor and will go unnoticed.

Positioned next to hot

General Notes
This product works best when supply temperatures and pressures remain
stable and within the product specifi cations, refer to section "Specifi cations".
If the supply conditions fall outside the specifi cations, the shower may go into
a safe shut down condition.
1. Plumbing
Refer to section: "Important Safety Information" fi rst.
1.1 Do not use sealing compounds on any pipe fi ttings or joints.
Supply pipework MUST be fl ushed to clear debris before connecting the Mira
Advance ATL. Debris will reduce the performance of the unit.
1.2 Avoid running the pipework through excessively hot or cold areas such as hot
loft spaces, airing cupboards, or in close proximity to hot water pipes. If this
cannot be avoided, we would recommend insulating the pipes.
1.3 Never fi t the unit to hot water supplies or to gravity systems of any description.
Only fi t the product to a mains cold water pipe.
1.4 The Mira Advance A TL is suitable for installation within a shower area and must
be positioned over a water catchment area with the controls at a convenient
height for the user . The shower fi ttings should be positioned so that the handset
discharges down the centre line of the bath, or across the opening of a shower
cubicle, and must be directed away from the Mira Advance ATL.
1.5 The Mira Advance ATL is fi tted with an inlet connector assembly that is designed
to accept water supplies from the top or bottom. The water supply can be fed with
15 mm pipe or 10 mm microbore pipe, suitably adapted for the inlet connector
assembly . If 10 mm microbore is used, then an allowance for increased pressure
loss must be made to make sure that the minimum maintained inlet pressure
of 1 bar is achieved, refer to section: "Specifi cations".
1.6 The Mira Advance A TL must be fi tted onto the fi nished wall surface i.e. on top of
the tiles. Do not block the air ventilation gaps around the sides of the unit, either
by tiling up to the sides of the unit or by using a sealant around the case (Small
pillars moulded on to the back of the case allow air circulation). The appliance
is designed to be ventilated. Failure to do this may cause product failure.
1.7 We recommend that a non-restrictive (free fl owing) isolating valve is fi tted in
the cold water supply pipe to allow maintenance of the Mira Advance ATL. Do
not fi t a valve that has a loose washer plate (jumper) as this can lead to a build
up of static pressures.
1.8 When installed in very hard water areas (above 200 ppm temporary hardness)
your installer may advise the installation of a water treatment device, to reduce
the effects of limescale formation. Malfunction of the Mira Advance ATL due to
excessive limescale formation is not covered by the manufacturer's guarantee.
Your local water company will be able to advise the hardness of water in your
area.
INSTALLATION REQUIREMENTS
11
1.9 The hose should be fi tted through the hose retaining ring to prevent the handset
from dropping below the spill-over level of the bath or shower , which could lead
to contamination from backsiphonage.
The hose retaining ring should meet
the 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
checkvalve, e.g. the Mira DCVH, must be fi tted, refer to section:
"Accessories". The inclusion of the
Mira DCV -H will increase the required
supply pressure typically by 10 kPa
(0.1 bar).
Caution! Double checkvalves, fi tted
in the inlet supply to the appliance,
cause a pressure buildup, which could
exceed the maximum static inlet pressure for the appliance.
1.10 Avoid layouts where the shower hose will be sharply kinked. This may reduce
the life of the hose.

Level

2. Electrical
Refer to section: "Important Safety Information" fi rst.
2.1 In a domestic installation, the rating of the electricity supplier ’s fuse and the
consumer unit must be adequate for the additional demand. All Mira Advance
ATL electric showers are high power units, therefore it is essential to contact
your electricity supplier to make sure that the supply is adequate for the
product. Voltage drop due to local heavy demand will reduce the shower’s
performance.
2.2 The Mira Advance ATL must be earthed by connecting the supply-cable earth
conductor to the earth terminal.
Supplementary bonding: Within the bathroom or shower room, all accessible
conductive parts of electrical equipment and extraneous conductive parts (metal
parts) that are likely to introduce earth potential, must be electrically bonded to
earth using a minimum cable size of 4.0 mm
2
if the cable is not mechanically
protected, (2.5 mm
2
if mechanically protected).
2.3 The minimum required supply cable size must conform to BS 7671.
2.4 As a guide only, and in accordance with BS 7671 we recommend close circuit
protection:
i.e. 8.7 kW = 40 Amp
9.8 kW = 45 Amp
It is strongly recommended that a 30 mA Residual Current Device (RCD) is
included in the electrical circuit. This may be part of the consumer unit or a
separate unit.
A separate, permanently connected supply is taken from the consumer unit to
the appliance through a double-pole switch, which has at least 3 mm contact
separation. The switch can be a ceiling mounted pullcord type within the shower
room or a wall mounted switch in an adjacent room.
2.5 DO NOT twist the individual cable cores of either the live or neutral conductors,
as this will prevent them from entering the terminal block.
2.6 DO NOT exert strain on the terminal block. Make sure that the electrical
connections are tightly screwed down.
2.7 DO NOT turn on the electrical supply until the plumbing has been completed.

INSTALLATION
Plumbing Connection
1.1 Unscrew the Case Securing Screw
and carefully pull the bottom of the
Cover outwards and upwards off the
Case.
1.2 Remove the Inlet Shield, located over
the Inlet Connector Assembly.
1.3 When deciding the position of the
Mira Advance ATL on the wall, allow
100 mm minimum clearance to
the right hand side of the case, to
provide unrestricted access to the
inlet connector, for installation and
maintenance. Allow 10 mm minimum
clearance from the top of the case to
allow the cover to be removed.
1.4 Determine whether the cold water
and cable supplies will be top (falling),
bottom (rising), or rear inlet to the
Mira Advance A TL. Provision must be
made for routing the signal cable from
the appliance to the Shower Drain
pump (up to 2 m), this applies to the
Standard Extra and Flex Extra models
only.
Note! Rear inlet must allow access to
the water supply pipe fi ttings.
Refer to section: "Important Safety Information" fi rst.
This installation covers all models of the Mira Advance ATL Thermostatic
shower.
Warning! Isolate the electrical and water supplies before proceeding with the
installation of the Mira Advance ATL. The electricity supply must be turned off at the
mains and the appropriate circuit fuse removed, if applicable.
Note! Bottom inlet is illustrated for clarity in these instructions.
