Electrical
1.In a domestic installation, the rating of the electricity supply company fuse and the consumer unit must be adequate for the additional demand. This is a high- power appliance, and it is essential to contact your electricity supply company to ensure that the supply is adequate for the appliance. Voltage drop due to local heavy demand will reduce the performance of the shower.
2.The appliance must be earthed by connecting the
Supplementary bonding: Within the bathroom or shower room, all accessible conductive parts of electrical equipment and extraneous conductive parts that are likely to introduce earth potential, must be electrically bonded to earth using a minimum cable size of 4.0 mm2 if the cable is not mechanically protected (2.5 mm2 if mechanically protected).
3.The minimum cable size
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.
4.To obtain full advantage of the power provided by this unit, use the shortest possible cable route from the consumer unit to the shower.
5.A 30 mA residual current device (RCD) should be fitted. This may be part of the consumer unit or a separate unit.
