Avoid layouts where the shower hose will be sharply kinked. This may reduce
the life of the hose.

2.1.
In a domestic installation, the rating of the electricity supply fuse and the
consumer unit must be adequate for the additional demand. As this Mira Go is
a high power unit, it is essential to contact your electricity supply company to
ensure that the supply is adequate for the Mira Go. Voltage drop due to local
heavy demand will reduce the shower's performance.
2.2.
The Mira Go
must be earthed
by connecting the supply-cable earth conductor
to the earth terminal.
Supplementary bonding:
Within the bathroom or shower room, all accessible
conductive parts of electrical equipment and extraneous conductive parts
(metal parts) that are likely to introduce earth potential, must be electrically
bonded to earth using a minimum cable size of 4.0 mm
2
if the cable is not
mechanically protected (2.5 mm
2
if mechanically protected).
2.3.
The minimum cable size (cross-sectional area) required is 6 mm
2
under normal
conditions of installation.
Important!
The shower circuit should be separated from other circuits by at
least twice the diameter of the cable or conduit and it should not be run through
thermally insulating material or in locations where the ambient temperature is
likely to exceed 30 °C. If any of these conditions are unavoidable it is necessary
to determine the cable size which will prevent damage to the cable caused by
overheating.
