fused spur.
Easily Accessible
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.
Ensure the switched fused spur is easily accessible for servicable and resetting
purposes.
The use of supply-line or zone strainers will reduce the need to remove debris
at the Digital Mixer Valve. The recommended maximum mesh aperture
dimension for such strainers is 0.5 mm.
Pipework
must
be rigidly supported to avoid any strain on the connections.
A 30 mA Residual Current Device (RCD)
must
be included in the electrical
circuit. This may be part of the consumer unit or a separate unit.
