Setup and Installation
The FRX-YW003 Pre-Filter is designed for simple, manual installation with standard garden hoses.
Installation Steps:
- Identify Connections: Locate the inlet and outlet ends of the filter. One end typically has a male threaded connection, and the other a female threaded connection.
- Connect to Water Source: Attach the female threaded end of the pre-filter to your garden hose. Ensure a snug, hand-tight connection to prevent leaks.
- Connect to Filling Device: Attach the male threaded end of the pre-filter to your desired filling device, such as a spray nozzle or directly to the hot tub/pool inlet. Ensure a snug, hand-tight connection.
- Initial Flush (Recommended): Before first use, slowly turn on the water supply and allow water to flow through the filter for 1-2 minutes. This flushes out any loose carbon fines and prepares the filter for use.

Maintenance
The ClurTech FRX-YW003 Pre-Filter is a disposable unit and requires no internal maintenance. Its effectiveness diminishes over time and with usage.
Filter Replacement:
- Replace the filter after filtering approximately 8,000 gallons of water.
- Replace the filter if you notice a significant decrease in water flow, or if the water quality (taste, odor, clarity) begins to decline.
- For optimal performance, it is recommended to replace the filter at least every 6 months, even if the 8,000-gallon capacity has not been reached, especially with frequent use or poor source water quality.
To replace, simply disconnect the old filter and install a new ClurTech FRX-YW003 Pre-Filter following the 'Setup and Installation' steps.
