INSTALLATION Note: in an Existing concrete slab, it is recommended to install an 80mm Puddle Flange onto the pipework at the exact waste outlet position prior to waterproofing. (5) 5 For New concrete slabs, Roca recommends the following procedure: 1. Pre-install and waterproof a drainage device into the concrete such as Iplex® Smart-Pan into which the Cyprus Shower Floor Waste outlet can be fitted directly. 2. Spread a 10mm min. thick mortar bed of 4:1 Washed Sand/Cement over entire area where the Cyprus Shower Floor is to be ins-talled and trowel off level or use a cement based tile adhesive. Spread on floor with a 12mm notched trowel to ensure the entire underside area of the Cyprus Shower Floor is fully supported. NOTE: Do not use silicone and/or ‘Liquid Nails’ type adhesives to adhere the Cyprus Shower Floor to place! 3. Lay the Cyprus Shower Floor on prepared levelled mortar bed and using a spirit level ensure the Cyprus Shower Floor is level both side to side and front to rear. This will allow the Cyprus Shower Floor to drain effectively as it has an inbuilt fall to the waste outlet. 4. At this point it is imperative to test for water run off to outlet prior to backfilling opening in slab, to ensure the Cyprus Shower Floor drains correctly. 5. Install the Waste outlet into the Cyprus Shower Floor. Note that the outlet is to be threaded in the anti-clockwise direction from the top of the Cyprus Shower Floor. Refer to waste outlet instructions. Ensure correct engagement of the Waste outlet with drainage device, or if using boxed opening – have the pipework connected to the waste outlet. 33
