4. Operating Instructions
Follow these steps for effective cleaning:
- Submerge the Vacuum: Fully submerge the vacuum head and the transparent debris collection chamber into the water of your pool or hot tub. Ensure no air is trapped inside the chamber.
- Position Over Debris: Guide the vacuum head over the area containing sand, gravel, or other debris you wish to remove.
- Initiate Suction: Firmly pump the handle up and down. Each pumping motion creates suction, drawing water and debris into the transparent filter chamber.
- Collect Debris: Continue pumping and moving the vacuum slowly over the dirty areas. The debris will be visible accumulating in the see-through filter.
- Empty Filter: When the filter chamber appears full or suction decreases, remove the vacuum from the water and empty the collected debris.
- Repeat: Re-submerge and continue cleaning until the desired area is clear of debris.
5. Maintenance
Regular maintenance ensures optimal performance and extends the life of your vacuum.
- After Each Use: Empty the debris from the transparent filter chamber. Rinse the filter and the entire vacuum head thoroughly with clean water to remove any remaining particles.
- Storage: Store the vacuum in a clean, dry place away from direct sunlight and extreme temperatures. Utilize the wall mounting bracket for convenient and organized storage.
- Inspection: Periodically inspect the vacuum for any signs of wear, cracks, or damage. Ensure all parts are securely attached.
6. Troubleshooting
If you encounter issues with your Kokido K738CBX, refer to the following common problems and solutions:
- No Suction or Weak Suction:
- Ensure the vacuum head is fully submerged in water and no air is trapped.
- Check if the transparent filter chamber is full of debris and needs emptying.
- Verify that all connections on the vacuum unit are secure.
- Ineffective Debris Collection:
- Pump the handle more vigorously and consistently.
- Move the vacuum head more slowly over the debris to allow sufficient time for suction.
