With an appropriate silt trap installed, dig a trench to the sizes detailed in Fig. A for the required run length. Pour a layer of semi-dry concrete in the bottom of the trench to the depth shown, the concrete used should be to the strength of a C25 mix. The top of the channel should lay 3-5mm below the top level of the paving material once installed.

Align the chosen exit point with the drain outlet and slot into place, bedding the channel down into the concrete base. Lay the adjacent channels, bedding down as you go. Joints between channels should be sealed with a suitable silicone or polysulphide sealant. Once bedded, haunch the channels in place to fully support the side walls of the channel.

To remove the appropriate exit point, use either a heavy duty knife or 80mm hole saw prior to installing the channel.

Once the channel is installed, fit the Leaf Trap into the outlet hole which has been created.

The End Cap can be fitted to either the male or female end of the channel. To fit it to the male end, first remove the thinned tabs using either a pair of pliers or heavy duty knife. Seal with a suitable silicon or polysulphide sealant.

The 1m lengths of channel can easily be sawn down at several points along their length. There are saw points located on the underside of the product, next to the vertical ribs. By using these points, the interlock feature can be maintained.

To create a junction, use a Manthorpe Junction Unit. Simply remove the correct blanked off sides with a craft knife to create either a 90° corner, T-junction or 4-way junction.

To remove the grate, use a flat blade screwdriver at the clip points to ease the clips open. The grate can be further secured using 4 3.5 x 30mm self tapping screws.
