2.7. The appliance must be earthed by connecting the supply cable earth
conductor to the earth terminal. All exposed metal parts within 3 metres of
the shower, within the shower room, must be electrically bonded to earth
using a minimum cable size of 2.5 millimetres
2.8. Do not turn on the electrical supply until the plumbing has been completed,
and the pump primed, as the unit must not be operated dry (see Section 7,
Commissioning).
2.9. The appliance is fitted with a pump motor, and some mechanical noise can
be expected from the appliance in addition to the noise generated by the
spray from the handset. The type of wall surface will affect the perceived
sound levels. Stud partition and panel walls have a tendency to resonate,
whilst solid walls will provide the quietest operation. The tone of the pump
motor may change when the temperature control knob is adjusted. This is
quite normal.
