2. Setup and Installation
2.1 Pre-Installation Checklist
- Ensure you have a YoLink Hub (Ethernet or 2.4 GHz Wi-Fi) installed and configured.
- Verify your main water line pipe size. This model is for 0.75" pipes.
- Gather necessary plumbing tools (pipe wrench, thread sealant, pipe cutter, etc.).
- Locate a suitable installation point on your main water line, preferably after the main shutoff valve and before any branches.
2.2 Installation Steps
- Shut off Main Water Supply: Turn off the main water supply to your home.
- Drain Water Lines: Open a faucet at the lowest point in your home to drain residual water from the pipes.
- Cut Pipe: Carefully cut a section of your 0.75" main water pipe where the FlowSmart device will be installed. Ensure the cut section matches the length of the FlowSmart unit plus any required fittings.
- Install FlowSmart Unit: Install the FlowSmart unit into the cut section of the pipe, ensuring the flow direction arrow on the device matches the direction of water flow. Use appropriate thread sealant on all connections to prevent leaks.
- Secure Mounting: Securely mount the FlowSmart unit to a wall or stable surface using the provided mounting hardware.
- Restore Water Supply: Slowly turn the main water supply back on and check for any leaks.
- Power On: Ensure the battery is correctly installed in the FlowSmart unit.
- Pair with YoLink Hub: Follow the instructions in the YoLink app to add and pair your FlowSmart device with your YoLink Hub.
