Installation Instructions For Sliding Door Units
NOTE: Our Sliding doors are subject to quality inspections before leaving our premises and are fully functional and square.
1. After placing the slider in the position, ensure the sill is absolutely straight and level.
NOTE: A builders string line is a handy tool that can easily show sagging of the top frame, bowing in the sides of the frame and if the sill is not straight and level.
2. The set-up of the frame must be 100% level, vertically as well as horizontally.
3. Verify this by opening and closing the sliding door, the running door should close firmly, if not the set-up is not correct.
4. Make sure the slider is built in the correct way around. (glass is installed from the outside)
5. Build up both sides of the sliding door at the same time without any unnecessary inward pressure that will bow the frame.
6. Frequently open and check that the runner is running smoothly and closes firmly against the frame or each other (do so before building in the lintel).
7. The lintel that is on top of the door must be supported to be able to take the weight of the bricks. The support must stay in place until the cement is dry to prevent the top from sagging. A gap between
the top of the frame and the lintel is recommended as sagging does take place and can cause the doors to be firmly wedged, making servicing difficult if not impossible. (Recommended gap = 20mm)
8. To verify that the lintel is not sagging, the gap from the top to bottom between the sill and the upper frame must measure the same.
9. Ensure at all times that no plaster, sand or any other foreign materials are wedged between the sliding door and the fixed door and that the sliding track is also kept clean.
10. Ensure at all times that the frame and doors are treated with penetrating oils and are kept clean of wet plaster and cement.
NB: The majority of problems on Sliding doors are caused due to sagging of lintels, sill not being level, and pressure transferred on the frame from the side walls.
The company does not accept any responsibility for any defects if these procedures have not been followed.
