The natural flexibility of the pipe should be used wherever possible to overcome obstacles and to form changes of direction. Cold-formed bends can be made by hand and fixed in position by fixing clips. Do not bend the pipe excessively as it may kink. Minimum bend radii should be observed to ensure pipe longevity, see table 8 below.

Pipes should be fixed using either the nail or screw clips. Nail clips are primarily designed for fixing to timber where pipe installation is not required.

If the installer intends to use screw clips other than Equator, these should be the clip-lock type, not the open saddle type.

Where piping is to be insulated, pipe clip spacers should be used with screw clips.

Where piping is to run adjacent to a suitable support member and does not require lagging the use of plastic cable ties is acceptable, providing they are suitable for the operating temperature of the system.

The recommended support distances, shown in Table 9, should be used when good pipe alignment is critical for proper system operation, ie. for a horizontal section of a vent pipe or when maximum neatness is required.

When 10mm or 15mm piping is run within a concealed void, it is usually acceptable to reduce the pipe fixing providing the risks listed under 'routing of pipework' can be avoided, as detailed in the Equator Design and Installation Guide.

For visible surface fixed pipework a rigid pipe should be used, such as copper.
