1. Schlüter-BARA-RKL/-RKLT must be attached to the substrate prior to installing the waterproofing assembly, for example with a cold bitumen adhesive. The abutment areas of the profiles should be sealed (e.g. with a butyl adhesive tape). Next, install the waterproofing membrane just up to the drainage openings to ensure that no other drainage channels remain open. Prior to this, the abutting edges of the profiles must be sealed e.g. adhesive butyl tape. Note: The applicable standard requires a width of 150 mm for integrated zinc or copper sheets. It is therefore recommended to discuss this issue with the customer before installing Schlüter-BARA-RKL, which has a width of 110 mm.
2. If the waterproofing has already been installed, attach the profile to the waterproofing assembly with a suitable adhesive and adjust the profile to position. Ensure that the waterproofing layer is already connected to a drip lip or gutter system. 
3. 1. If Schlüter-BARA-RKL/-RKLT is used as a gravel edge profile, the gravel layer is spread over the drainage mat Schlüter-TROBA or Schlüter-TROBA-PLUS and should abut the vertical profile leg just below the upper lip. The gravel or crushed stone must be contained to stabilize this edge area. The pavers are then laid loosely on top of the levelled gravel layer.
   2. If Schlüter-BARA-RKL/-RKLT is used in conjunction with stilted floor coverings such as Schlüter-TROBA-STELZ, the support pedestals are laid on top of the anchoring leg of Schlüter-BARA-RKL/-RKLT. The gravel or crushed stone must be contained to stabilise this edge area. The pavers are then set onto the pedestals. 
4. Abut the profile ends of Schlüter-BARA-RKL/-RKLT, leaving an approx. 5 mm joint, then cover the joint with the snap-on connector. Prefabricated internal and external corners are available.
5. Once the covering is completely installed, the Schlüter-BARIN gutter system can be fastened to the Schlüter-BARA-RKLT profile using the screws included. The slotted holes allow for slope adjustment, if required.

Note: Make certain during installation that the drainage openings of Schlüter-RKL/-RKLT remain open.
