2.1.
The electrical installation must comply with the “Requirements for Electrical
Installations” commonly referred to as the IEE Wiring Regulations, or any
particular regulations and practices, specified by the local electricity supply
company in force at the time of installation.
2.2.
In a domestic installation, the electricity company fuse must be a minimum
of 80 Amps. As the Elite 2 is a high power unit it is essential to contact your
electricity supply company to ensure that the supply is adequate for the
purpose.
Mira Elite 2 9.8 @ 240V 45 Amps
Mira Elite 2 9.0 @ 230V 40 Amps
Note!
Voltage drop due to local heavy demand will reduce the shower
performance.
2.3.
A separate permanently connected supply must be taken from the
consumer unit to the shower, via a double pole switch, with at least a 3 mm
contact separation. The switch can be a ceiling mounted pullcord switch
within the bathroom, or a wall mounted switch in an adjacent room.
Suitable ceiling mounted pullcord switches for Mira electric showers

2.4.
The minimum cable size required is 6 mm
2
. To obtain full advantage of the
electrical power provided by the Elite 2, use the shortest possible cable
route from the consumer unit to the Elite 2.
As a guide only, the maximum 6 mm
2
cable length allowed with a 5 Volt
drop and RCD installed, is 16 m for an Elite 2, 9.8. If longer cable runs are
required then 10 mm
2
should be used. Refer to the IEE Wiring Regulations
for further clarification.
2.5.
We recommend the inclusion of a 30 mA residual current device (RCD).
This may be part of the consumer unit or a separate unit.
2.6.
The terminal block will not accept cable larger than 16 mm
