Introduction
The Waterco MultiCyclone 16 is an innovative pre-filtration device designed to reduce the load on your primary pool filter. Utilizing centrifugal technology, it separates up to 80% of the incoming dirt and debris before it reaches your main filter, significantly extending the time between filter cleanings and reducing water consumption. This manual provides essential information for the proper installation, operation, and maintenance of your MultiCyclone 16 to ensure optimal performance and longevity.

Setup and Installation
Proper installation is crucial for the efficient operation of the MultiCyclone 16. It should be installed between the pool pump and the main filter.
Placement Considerations
- Ensure a minimal clearance of 12 inches (30 cm) on all sides of the unit for proper air circulation and access for maintenance.
- Install the unit on a stable, level surface capable of supporting its weight when full of water.
- Position the unit to allow easy access to the sediment purge valve.
Piping Connections
- Connect the outlet from the pool pump to the inlet of the MultiCyclone 16.
- Connect the outlet of the MultiCyclone 16 to the inlet of your main pool filter.
- Install a purge valve at the bottom of the MultiCyclone 16 sediment chamber, connected to a waste line or suitable drainage area.
- Ensure all connections are watertight using appropriate sealants and fittings.
Initial Startup
- Before starting the pump, ensure all valves are open and the system is primed according to your pump manufacturer's instructions.
- Slowly open the main filter's inlet valve to allow water to fill the MultiCyclone 16 and the main filter.
- Once the system is full of water, start the pool pump.
- Check for any leaks and rectify them immediately.
Operating Instructions
The MultiCyclone 16 operates continuously with your pool pump, requiring minimal user intervention during normal operation.
How it Works
Water enters the MultiCyclone 16 and flows through multiple hydro cyclones, creating a centrifugal effect. This forces heavier particles of dirt and debris to the wall of the hydro cyclone and then spirals them down to the sediment collection chamber. The cleaner water then flows upwards from the center of the hydro cyclone and out to the main filter. This process effectively removes a significant amount of particulate matter, reducing the workload on your primary filter.
Regular Checks
- Periodically inspect the clear sediment chamber to monitor the accumulation of debris. The frequency of purging depends on the amount of debris collected.
- Ensure there are no obstructions in the inlet or outlet pipes.
Maintenance
The primary maintenance task for the MultiCyclone 16 is flushing the sediment chamber.
Flushing the Sediment Trap
- Turn off the pool pump.
- Close the valve on the main filter's inlet line to isolate the MultiCyclone 16.
- Open the purge valve at the bottom of the sediment chamber. This will allow the accumulated dirt and debris to be flushed out.
- Allow water to flow until the water running clear, indicating that the sediment chamber is clean.
- Close the purge valve.
- Re-open the main filter's inlet valve.
- Restart the pool pump.
Frequency: The frequency of flushing depends on the pool's debris load. In heavily used pools or after storms, flushing may be required daily or weekly. For cleaner pools, monthly flushing may suffice. Observe the clear sediment chamber to determine the optimal schedule.
General Cleaning
- Periodically wipe down the exterior of the unit with a damp cloth to remove dust and grime.
- Avoid using harsh chemicals or abrasive cleaners, as these can damage the unit's materials.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Reduced water flow through the system. | Sediment chamber is full. | Flush the sediment trap as per maintenance instructions. |
| Water leaking from connections. | Loose fittings or damaged O-rings/seals. | Tighten all connections. Inspect and replace any damaged O-rings or seals. |
| Excessive debris reaching the main filter. | Infrequent flushing of the MultiCyclone 16. | Increase the frequency of sediment trap flushing. Ensure the purge valve is fully closed after flushing. |
