2. Preparing the exterior Door for Installation
There are two simple steps that need to be performed to perfectly prepare the new element for installation:
Before you install the frame, you need to remove the protection foil from the outer shell of the frame completely, because this is difficult to achieve afterwards. The foil should be removed 3 months after delivery at latest, to prevent residue from remaining (Fig. 2).
In order to install the new exterior door leaf, the old one has to be removed from the frame. Remove the locking pins from the hinges (The removing direction can differ depending on the mechanism). You can now lift off the leaf (Fig. 3).
