Panel distortion – laminate board, e.g. due to changes in humidity. Milling-in grooves on the rear side of the door. Groove width 2–3 mm, groove depth lamino 10 mm – ca. 3 mm, lamino 18 mm ca. 8 mm. Note that laminate board manufacturers recommend edging boards as well as sides that are hidden in the profile due to possible damp suction. In damp environments and in areas with substantial change of ambient conditions, it is necessary to use more solid profiles. Additional door straighteners must be used in extreme conditions. Excessive difference between the thickness of lamino and the groove in the profile. Laminate boards have certain manufacturing tolerance and tolerance also applies to aluminium profiles. In the event that the thickness of the laminate panel exceeds the groove dimension in the profile, we recommend milling off the excess to a maximum of 0.1–0.2 mm above the standard dimension. Twisting of the panel due to varnishing, veneering, etc. These processes may cause a considerable twisting of the board. To decrease the risk, it is possible to use the same technology also for the other side of the board. Sticking the glass panel on a laminate board 12 mm. We recommend using double-sided adhesive tapes to attach glass panels. The drawing with the instructions shows placement of the adhesive tape, the largest area is placed at the bottom part of the door, the amount of the tape at the top may be smaller. We strongly warn against using glues and silicone. In such a case, there is a risk of substantial twisting of the door without any possibility of repair. Door bending with frame systems. Used panels not perpendicularly cut, uneven lengths of sides. Check whether the panels are cut correctly, possibly cut them down to the correct dimensions. Horizontal frame strips are not perpendicularly cut. Check whether the profiles are cut correctly, possibly cut them down to the correct dimensions. Deformation of profiles due to excessive tightening of connecting screws. When tightening the connecting screws, make sure that the profiles are not deformed due to the excessive tightening of screws. Required dilatation 4 mm not complied with or cut to larger dimensions. Dismantling the door and cutting it down to the right size. Friction of the door against bottom guide Bottom rail placed on an uneven surface, non-adjusted door. Align the base under the rail. Adjust bottom running components – the height of the door above the rail. Friction of the door against top guide. Unevenness between top and bottom guide. Compare positioning of top and bottom guide so that they are parallel. Incorrectly localised inner dimension and the subsequent wrong dimensions of the door. Measure the inner dimensions of the cabinet and check the cabinet size, reduce the door height if necessary. Braking of the door with a soft closer, noticeable resistance when moving. Incorrectly mounted soft closer, incorrectly adjusted running component castors. The soft closer has an adjustable pitch of castors for different types of guides. It is necessary to adjust the pitch so that the door moves without any play but the pressure is not too strong. Friction of the door with a soft closer. Incorrectly adjusted running component castors. The door must not touch the guide, it is necessary to adjust the running components so that any contact is prevented. Friction of bottom running components, noise during movement. Dirt in guides. Vacuum any dirt in guides, wipe the guides. Bottom running components damaged by dirt in guides (e.g. a paper clip in the guide). Replacement of running components. Damage of guides – e.g. little stones in a shoe, etc. Replacement of bottom guide. Rustling sound when moving the door. Backstop or anti-dust brush slid down in the handle profile groove and rubs against the guide. Use a staples to fasten the brush, press the bottom end of the handle profile.
