3.3 Water Source Installation

1. Close the water supply: Turn off the valve to stop the water flow.
2. Install the Three-Way Ball Valve: If necessary, use the included 3/8-inch adapter or purchase a suitable adapter for a 1/2-inch valve. Tighten the valve using a wrench.
3. Extend the pipe from the base station to the water source, ensuring adequate length. Trim excess pipe and ensure a clean incision.
4. Insert the water purification tube into the hole in the front water tank. Connect the Three-Way Ball Valve.
5. Insert the 3/8-inch Pipe Check Valve into the front tank. Pay attention to the installation orientation and make sure to point from the front water tank to the sewage outlet.

3.4 Drain Pipe Installation

1. Use the Y-Shaped Merging Pipe to combine the overflow and drain pipes. Insert the drain pipe into the outlet.
2. Adjust the drainage method based on the installation location. Do not install a check valve at the drainage outlet to avoid system failure caused by excessive drainage pressure.
3. Method 1: Directly insert into the existing sewage outlet. Insert 20cm or more and fix in place.
4. Method 2: Secure Drainage Components: Install the Wastewater Clip onto the drain pipe and tighten the screws.

3.5 Installing the Front Water Tank

1. Confirm the approximate installation location.
2. Clean and smooth the installation wall.
