1. Once the timber frame has been erected, remove all transportation fixings (retaining screws) from the window brackets in the external reveal.
2. Push the window outward ensuring brackets are fully extended.
3. Re-fit transportation screws back into the same fixing hole in the bracket now on the inside reveal to secure the window in place.
4. Fit external cill (if required) and screw to the bottom of the window.
5. If the window is greater than 1300mm wide an L-shaped bracket is to be fitted to the underside of cill to prevent window flex.
6. Fit handles and SlotVents if they have not already been installed.
