Installation instruction


Time-saver! Profit of labour! Financial profit !

1/ Place the two grips opposite one the other on the rails

2/ To block the grips on the rails use the screws butterfly (assembly without tool).

3/ Slip the central bracket on the bar. Slip the bar into the brackets. Push the springs to block the bar (assembly without tools).

4/ Screw the nipples on coupling. Curve the flexible manually in order to position reducer at the desired place (respect minimum radius bend). Leave at least a length of 64mm without curve each side of the flexible hose.

5/ Adjust the height of the reducer with the celing. Move the reducer vertically and push the spring downwards to block the unit (assembly without tools).
