We recommend, for additional protection, the pump
to be supplied from socket outlet protected by
a residual current device – RCD (also known as
an Earth Leakage Circuit Breaker – ELCB) with a
maximum rated residual current of 30mA.
Should you the installer or owner be unfamiliar with the correct
installation or operation of this type of equipment you should contact
the distributor/manufacturer for the correct advice before proceeding
