IMPORTANT SAFETY INFORMATION
Installation must be carried out in accordance with these instructions, and must be
conducted by designated, qualied and competent personnel.
WARNING!
Follow all warnings, cautions and instructions contained in this guide, and on or
inside the shower.
1. This shower can deliver scalding temperatures if not installed or
maintained in accordance with the instructions, warnings and cautions
contained in this guide and on or inside the appliance.
2. This product is suitable for installation within Zone 1 and is rated IPX4.
3. Isolate the electrical and water supplies before commencing installation. The
electricity must be turned off at the mains and the appropriate circuit fuse
removed, if applicable.
4. Mains connections are exposed when the cover is removed.
5. Refer to the wiring diagram before making any electrical connections.
6. Make sure all electrical connections are tight, to prevent overheating.
7. Make sure that any pipework that could become frozen is properly insulated. The
shower unit must not be tted where it may be exposed to freezing conditions.
8. The water supplies to this product must 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.
9. DO NOT operate this appliance if it is frozen. Isolate the electrical supply and
allow to thaw. Check for leaks before reconnecting the electrical supply.

INSTALLATION REQUIREMENTS
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 possibility of
condensation on electronic components.
The shower works best when water supply conditions are stable and within the
specications, refer to section 'Specications'. If the supply conditions fall outside
the specications, 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.
Route cable and pipe supplies via the cut outs moulded in the case and cover.
DO NOT increase the size or cut alternative pipe / cable entry points as water ingress
into the product may occur.
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 ttings 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.
10
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 and may damage
the product.
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 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.
Hose Retaining Ring tted and shower ttings xed at a suitable height preventing
dirty water backow.

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
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 within
the shower room 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 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.
1.9 The position of the shower and shower ttings must provide a minimum gap of
25 mm between the showerhead and the spill over level of any bath, shower
tray or basin and a minimum gap of 30 mm between the showerhead and the
spill over level of any toilet, bidet or other appliance with a Fluid Category 5
backow risk.
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
10kPa (0.1 bar). Double checkvalves tted in the inlet supply to the appliance cause
a pressure build up, which affect the maximum static inlet pressure for the appliance
and must not be tted. For Fluid category 5 double checkvalves are not suitable.
1.10 Wall xings are supplied for solid wall structures. For other wall structures such
as panels alternative xings may be required. A minimum of 2 xing screws
must be used.
