To prevent deflection, the door must be stored horizontally on a flat surface before installation.
Do not store doors near heaters or drafts, as rapid changes in air temperature can cause cracks on the door surface and other deformations. During storage, direct sunlight on the door parts must be avoided - this can lead to an uneven exit of the color coating of the door. It is recommended to store the door in its original packaging.
It is strictly forbidden to store the door, even in the original packaging, in rooms where wet construction work is performed, for example, wall painting, puttying, filling, smoothing, etc.
