Milling-in grooves on the rear side of the leaf. 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 leaf 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 case that the thickness of the laminate board exceeds the size of the groove in the profile, we recommend milling off the excessive dimension to max. 0.1–0.2 mm over the standard dimensions. 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 leaf, 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 leaf 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 leaf and cutting it down to the right size. Friction of the leaf against bottom guide Bottom rail placed on an uneven surface, non-adjusted leaf. Align the base under the rail. Adjust bottom trolleys – the height of the leaf above the rail. Friction of the leaf 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 leaf. Measure the inner dimensions of the cabinet and check the cabinet size, reduce the leaf height if necessary. Braking of the leaf with a soft-closing system, noticeable resistance when moving Incorrectly mounted soft-closing system, incorrectly adjusted trolley castors. The soft-closing system has an adjustable pitch of castors for different types of guides. It is necessary to adjust the pitch so that the leaf is not loose when moving and the pressure is not too strong. Friction of the leaf with a soft-closing system Incorrectly adjusted trolley castors. The leaf must not touch the guide, it is necessary to adjust the trolleys so that any contact is prevented. Friction of bottom trolleys, noise during movement Dirt in guides. Vacuum any dirt in guides, wipe the guides. Bottom trolleys damaged by dirt in guides (e.g. a paper clip in the guide). Replacement of trolleys. Damage of guides – e.g. little stones in a shoe, etc. Replacement of bottom guide. Rustling sound when moving the leaf Backstop brush or dust brush slid down in the handle groove and rubs against the guide. Use a clip to fasten the brush, press the bottom end of the handle profile.
