SHOWER PERFORMANCE
What affects shower performance?
The shower'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 owing through the appliance. Any of the following conditions can cause the
shower to change the ow rate (force of the shower) in order to keep the temperature
constant. Most changes are minor and will go unnoticed.

General
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 Do not use sealing compounds on any pipe ttings or joints.
1.2 To avoid damage to the case when soldered ttings are used, pre-solder
the pipework and fittings before connecting them to the inlet connector
assembly.
1.3 Never t the appliance to hot water supplies or to gravity systems of any
description. Only t the product to a mains cold water pipe.
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 appliance must be tted onto the nished wall 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 to allow maintenance of the appliance.
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.
INSTALLATION REQUIREMENTS

13
1.9 Caution! Double checkvalves, tted in the inlet supply to the appliance, cause
a pressure buildup, which could exceed the maximum static inlet pressure and
cause water to leak into the appliance.
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
ATL electric showers are high power appliances. 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
9.8 kW = 45 Amp
A 30mA 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 is taken from the consumer unit
to the appliance through a double-pole switch. The switch can be a ceiling
mounted pullcord type or a wall mounted switch in an adjacent room.
2.4 DO NOT exert strain on the terminal block, however make sure that the electrical
connections are tightly screwed down.
2.5 DO NOT turn on the electrical supply until the plumbing has been completed.
2.6 Unless otherwise stated, electrical equipment such as extractor fans, pumps
must not be connected via this product.

Important! On initial installation, the appliance needs to 'learn' about the site
conditions and does so during the commissioning cycle. It is important that the shower
is commissioned correctly otherwise an error condition may occur. Once set, the
shower constantly updates it's memory with information about the site conditions to
deliver the best performance.
