4. Operation
The single-lever design allows for easy control of water flow and temperature.
- Water Flow: Lift the lever to turn on the water. The higher the lever is lifted, the greater the water flow.
- Temperature Control: Move the lever to the left for hot water and to the right for cold water.
- Adjustable Swivel Spout: The high spout can be rotated to direct water where needed. The swivel range can be set to 0°, 150°, or 360° during installation or adjusted later if needed.
- Window Functionality: For sinks located in front of a window, the faucet can be easily lifted straight up and laid horizontally on the countertop to allow the window to open.
