13. Operation – scheme C
Scheme C lift and slide elements have two controllable lift & slide sashes (primary sash and secondary sash ). The
primary sash is the initial opening sash and the secondary sash opens next. The primary sash and secondary sash positions
(right or left lift & slide sash) must be specified when placing your order. In the examples in these instructions, the left-hand lift
& slide sash is the primary sash and the right-hand lift & slide sash is the secondary sash.
Note: The button for the primary sash controls the corresponding lift & slide sash individually.
The button for the secondary sash controls both lift & slide sashes at the same time.
