Cutting & Assembly Instructions
For ease of cutting, we recommend the use of a compound mitre saw fitted with a multi-material cutting blade 80 tooth or more. A hole saw is also recommended to drill the hole for the waste outlet.
- 1. Cut the bottom tray 2mm shorter than desired length to allow end caps to be fitted.
- 2. Cut the top grate 1mm shorter than the bottom tray to allow for easy install and removal of top grate.
- 3. Using a 50mm hole saw, drill out drainage hole in the bottom tray only, at the required position depending on the location of the waste pipe.
- 4. Insert the end caps into the bottom tray and secure with a bead of silicone on the outside of tray
- 5. Place silicone around the lip of the pop waste and secure to the drilled hole on the underside of the bottom tray.
Installation to be by a licensed plumber and in accordance with AS/NZS 3500.2.
