General
We recommend that the product be brought into the room where it is to be installed
and left to acclimatise to room temperature, this will reduce the possiblilty of
condensation on electronic components. This product works best when supply
temperatures and pressures remain stable and within the product specications, refer
to section 'Specications'. If the supply conditions fall outside the specications,
the shower may go into a safe shut down condition.
If pipework and/or electrical cables enter the shower from the rear through a hole in
the wall, provision must be made to prevent water ingress back into the wall structure.
1. Plumbing
Refer to section: 'Important Safety Information' rst.
1.1 The shower is designed to operate with gravity fed water supplies providing
pressures from 0.8 kPa * (0.008 bar / 80 millimetres head) to 100 kPa (1 bar
/ 10 metres head) (i.e. the vertical distance from the base of the cold cistern
to the top of the main unit of the shower). The unit should be never be tted
to a mains supply or where the above maximum pressure may be exceeded.
Failure to comply with this may result in product damage leading to signicant
uncontrolled leakage from the unit.
* Note: In practice the minimum head required will increase with pipe length
and the guide given in the section 'Pipework' should be used to make sure
that adequate head is available for any given installation.
The shower MUST have its own separate supply from the cistern.
INSTALLATION REQUIREMENTS
Incorrect Cistern Take Off
Debris from the bottom of
the cistern and air generated
when the cistern rells will
enter the shower supply.
Correct Cistern Take Off
Positioned away from the ball
valve, with a 25 mm distance
up from the base of the cistern.
This connection will prevent air
and debris entering the shower
supply.

1.2 Do not use sealing compounds on any pipe ttings or joints.
1.3 To avoid damage to the case when soldered ttings are used, pre-solder the
pipework and ttings before connecting them to the inlet connector assembly.
1.4 Avoid layouts where the shower hose will be sharply kinked. This may reduce
the life of the hose.
1.5 Supply pipework MUST be ushed to clear debris BEFORE connecting the
appliance. Debris will reduce the performance of the shower.
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.
1.6 The shower must be tted onto a tiled or sealed nished surface, i.e. on top of
the tiles. DO NOT tile up to the sides of the shower or use a sealant around the
case. Failure to do this may cause appliance failure. To ensure the case and
other components are not put under strain during installation always provide
mechanical support when making plumbing connections. Upon completion of
the installation ensure connections and back case are not under any stress
due to misaligned pipework or electrical cables.
1.7 We recommend that a non-restrictive (free owing) isolating valve is tted in
the cold water supply pipe from the cistern to the shower, to allow maintenance
of the shower.
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. Any malfunction due to limescale is not
covered by the manufacturer's guarantee. Your local water company will be
able to advise the hardness of water in your area.
1.9 To prevent the possibility of backsiphonage, the handset must be prevented
from reaching within 25 mm of the spillover level of any bath, shower tray or
washbasin. The supplied hose retaining ring should enable this to be achieved
for the majority of shower installations. However, there will be occasions when
the hose retaining ring will not provide a suitable solution. In these instances,
a double checkvalve must be tted to the outlet. Double checkvalves tted in
the shower's inlet supply can cause a pressure build-up, which could exceed
the maximum static inlet pressure for the appliance. The handset must be
prevented from reaching within 30 mm of the spillover level of any WC, bidet
or other basin that is classied higher than uid category 3.
1.10 Rear entry plumbing is accommodated without the need to recess the 15 mm
inlet compression connector. If pipework and/or electrical cables enter the
shower from the rear through a hole in the wall provision must be made to
prevent water ingress back into the wall structure.
1.11 The shower is tted with a pump motor, and some mechanical noise can be
expected in addition to the noise generated by the spray from the handset. The
type of wall surface will affect the perceived sound levels. Stud partition and
panel walls have a tendency to resonate, whilst solid walls provide the quietest

11
operation. The tone of the pump motor may change when the temperature
control knob is adjusted. This is quite normal.
1.12 Use a minimum of 15 mm diameter supply pipework. It should be noted,
however, that on long pipe runs this should be increased to 22 mm (refer to
section 'Pipework' for guidance). When using exible plastic pipe it is essential
that the pipe is kept at and not looped up at any point as this may lead to air
build up.
1.13 Long pipe runs and excessive use of 90° elbows will signicantly reduce the
available head to supply the shower. The pipework table should be completed
to ensure that adequate head is available for any given application.
Pipework
The dimension (x) is calculated from the table below to give you a minimum effective
head of 80 mm which is necessary to produce a satisfactory shower in all conditions.
Example! The example below is based on the diagram above with 15 mm pipework,
A = 1.5 m, B = 0.75 m.

2. Electrical
Refer to section: 'Important Safety Information' 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
ATLP pumped electric showers are high power appliances, so it is essential to
contact the electrical supply company to make sure that the supply is adequate
for the appliance. Voltage drop due to local heavy demand will reduce the
shower’s performance.
2.2 The appliance must be earthed by connecting the supply-cable earth conductor
to the earth terminal.
Any supplementary bonding and supply cable size must conform to BS 7671.
2.3 As a guide only, and in accordance with BS 7671 we recommend close circuit
protection:
i.e. 9.0 kW = 40 Amp
In accordance with BS 7671,a 30 mA Residual Current Device (RCD) MUST
be included in the electrical circuit. This may be part of the consumer unit or a
separate unit.
A separate, permanently connected supply must 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 or a wall
mounted switch in the applicable zone area.
2.4 DO NOT exert strain on the terminal block. Make sure that the electrical
connections are tightly screwed down.
2.5 Unless otherwise stated, electrical equipment such as extractor fans, pumps
must not be connected via this product.
