2.4.
To obtain full advantage of the power provided by this unit the shortest possible
cable route from the consumer unit to the shower should be used. The maximum
permissible circuit length is dependent on current demand, voltage drop and
cable size, refer to the IEE Wiring Regulations for further information.
As a guide only,
the following maximum permissible lengths are given for 6
mm
2
cable protected by a 40A MCB type B and allowing for a 5 Volt drop:
Mira Go 8.5 kW (240 V AC) at 240 V - 19 Metres
2.5.
A 30 mA residual current device (RCD) should be fitted. This may be part of the
consumer unit or a separate unit.
2.6.
A separate, permanently connected electrical supply must be taken from the
consumer unit to the Mira Go through a double-pole switch, which has at least
3 mm contact separation. The switch can be a ceiling mounted pull-cord type
within the shower room or a wall mounted switch in an adjacent room.
2.7. DO NOT
twist the individual cable cores of the live and neutral conductors, as
this will prevent them from entering the terminal block.
2.8. DO NOT
exert strain on the terminal block.
2.9. DO NOT
turn-on the electrical supply until the plumbing has been completed and
the cover replaced.
