The hot and cold water supply drops (100mm between pipe centres) can be installed prior to fitting the panel. Position the panel on the wall at the appropriate height and mark the position of the hole in the centre of the top bracing strut. Drill a hole at the position marked, fit the support screw and hang the panel. Ensuring that the panel is hanging true and at the correct height, mark the position and then drill the four support holes. Attach the panel to the wall, refit the end caps then connect the supply pipes to the drops.
