5. Operating Instructions
The iVac250Li is designed for simple and effective pool and spa cleaning.
- Submerge the Cleaner: Slowly submerge the entire iVac250Li unit into the water. Ensure it is fully immersed before turning it on.
- Turn On: Locate the power switch (typically a button or toggle) on the unit and turn it on. The cleaner will begin to operate, creating suction.
- Begin Cleaning: Guide the cleaner along the bottom and sides of your pool or spa. Move it slowly to allow the vacuum to pick up debris effectively. The self-propelled feature assists in movement.
- Monitor Debris Chamber: Periodically check the clear debris chamber to see if it is full. If full, turn off the unit, remove it from the water, and empty the filter bag.
- Finish Cleaning: Once cleaning is complete, turn off the unit and remove it from the water.
