3 amp switched fused spur. Easily Accessible Mira Vier Shower Fittings & Wireless Controller A separate, permanently connected supply must be taken from the ring main to the appliance through a 3 amp double pole switched fuse spur providing a minimum 3mm contact separation gap in each pole. - Page 19 Long inlet pipework (dead-legs) should be kept to a minimum to avoid temperature fluctuations. Supply pipework layout must be arranged to minimize the effect of other outlet usage upon the dynamic pressures at the Digital Mixer Valve inlets. To eliminate pipe debris it is essential that supply pipes are thoroughly flushed through before connection to the Digital Mixer Valve.
