4. Setup and Installation
4.1 Unpacking
Carefully remove the dishwasher from its packaging. Inspect for any shipping damage. Retain packaging materials for future transport if needed. Remove any internal packing materials or tape.

Place the dishwasher on a stable, level countertop or shelf. Ensure there is sufficient space around the unit for ventilation and door opening. The dimensions are approximately 16.85"W × 16.73"D × 18"H. If not connected to a faucet, ensure extra height above the unit for manual water filling.
4.3 Water Supply Modes
The dishwasher offers flexible water supply options:
- Manual Fill: Use the provided pitcher to fill the built-in 5-liter water tank. Stop adding water when the "Full Water Level" alert sounds. This mode requires no plumbing connection and is ideal for portability.
- Faucet Fill Using Hose: Connect the inlet hose to a faucet. This is suitable when the dishwasher is close to a sink.
- Direct Water Line Hook-Up: For a more permanent setup, connect the inlet hose to a dedicated G3/4 inch water line. An adapter may be required depending on your faucet type.
