5. Operating Instructions
This section details how to operate your PYY Bun Steamer for optimal food warming and display.
- Power On: Turn the ON/OFF switch to the "ON" position. The power indicator light will illuminate.
- Load Food: Carefully place steamed buns, dim sum, or other food items onto the shelves. Ensure even distribution for consistent warming.
