I had presumed the instructions below meant that my power shower (no heater - integrated pump) must be fitted to the consumer unit or a separate shower unit attached directly to the cu.
However, I found this review and started wondering. Is it really necessary to wire to the cu as the power to the pump is relatively low? Remember there is no heater in this unit...
The mains supply must be 230–240 V at 50 Hz connected to the appliance
via a double pole switched 3 Amp fused connection unit (not supplied) with a minimum 3 mm contact separation gap in each pole.
The minimum cable size (cross-sectional area) required is 1mm2 under normal conditions of installation.
A 30 mA residual current device (RCD) must be fitted. This may be part of the consumer unit or a separate unit.

In terms of the electrical connection, due to the fact that this unit operates at 150 watts on a 3 amp fuse, I took a switched RCD spur off the lighting circuit - perfectly acceptable for this sort of current.
