6. Setup and Initial Use
Follow these steps to set up your Creality Space PI Filament Dryer:
- Placement: Place the dryer on a stable, flat surface away from direct sunlight, heat sources, and moisture.
- Load the Filament: Open the lid of the dryer and place your filament spool inside the compartment. Ensure the spool rotates freely on the internal rollers.
- Thread the Filament: Guide the filament through the outlet port and, if provided, through the Teflon tube. Ensure the filament can feed smoothly.
- Connect Power: Plug the power cable into the dryer's power input port and then into a suitable 110V 50/60Hz power outlet.
- Turn On: Flip the main power switch located at the rear of the unit to the 'ON' position. The LCD touch screen will illuminate.
