3. Setup
Proper installation is crucial for the performance and safety of your washing machine.
3.1. Placement Requirements
Ensure sufficient space around the washing machine for proper ventilation and operation. An additional 10cm width is required for installation clearance, especially when considering entryways, corridors, and elevator dimensions.

3.2. Water Supply and Drain Hose Connection
Connect the water supply hose (approx. 80cm length) to a suitable water faucet. The drain hose can be routed from either the left or right side of the machine, offering flexibility for various room layouts. Ensure the drain hose connection side has at least 9cm clearance.
