1. Find a suitable position near to the back of the sash track. Ensure that the sash handle does
not protrude into the light beam and that there are no other obstructions on either side wall.
2. Carefully remove the front plastic covers from the right-hand side of the light curtain
receiver and the left-hand side of the light curtain transmitter cases.

3. Position the light curtain transmitter and receiver on opposite sidewalls. Ensure that the
back of the sash handle does not penetrate the light beam path.
The sash light curtain transmitter and receiver should be fitted so that their cable entry / exit
points are at the top.
Ensure that the light beam path is free from other obstructions.
