Installation and Replacement Instructions
Replacing the ASR412-1000G RO filter in your Frizzlife PD1000-TAM4 system is a quick and tool-free process. Follow these steps:
- Shut Off Water Supply: Before beginning, locate the water supply valve to your Frizzlife PD1000-TAM4 system and turn it off completely. This prevents water leakage during filter replacement.
- Release Pressure (Optional but Recommended): Open the filtered water faucet to release any remaining pressure in the system. Close the faucet once water stops flowing.
- Remove Old Filter: Identify the 2nd stage RO filter (labeled 'RO') on your PD1000-TAM4 system. Gently twist the old filter cartridge counter-clockwise until it detaches from the system head. Some residual water may drip out.
- Prepare New Filter: Remove the new ASR412-1000G filter cartridge from its packaging. Ensure the O-rings are properly seated.
- Install New Filter: Align the new filter cartridge with the corresponding port on the system head (the 'RO' port). Insert the filter and twist it clockwise until it is securely locked into place. You should feel a click or firm stop.
- Restore Water Supply: Slowly turn the water supply valve back on. Check for any leaks around the newly installed filter.
- Flush the System: Open the filtered water faucet and allow water to run for approximately 5-10 minutes to flush out any air and carbon fines from the new filter. This ensures optimal performance and taste.
Note: For detailed visual instructions, refer to the official Frizzlife PD1000-TAM4 system manual or visit the Frizzlife support website.
Maintenance and Filter Lifespan
The Frizzlife ASR412-1000G RO filter cartridge has an estimated lifespan of up to 2 years. However, the actual replacement period can vary significantly based on several factors:
- Feed Water Quality: Water with higher levels of contaminants (e.g., sediment, chlorine, hardness) will reduce the filter's lifespan.
- Daily Water Consumption: Higher daily usage of filtered water will necessitate more frequent filter changes.
It is recommended to monitor your filtered water's taste and flow rate. A noticeable decrease in flow or a change in taste indicates that the filter may need to be replaced sooner than the estimated lifespan.
For optimal performance and continued access to high-quality purified water, adhere to the recommended replacement schedule or replace the filter when signs of reduced performance appear.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Water Leakage after Replacement | Filter not fully seated or O-rings misaligned/damaged. | Ensure the filter is twisted firmly into place. Remove and re-install, checking O-rings for proper seating or damage. |
| Low Water Flow Rate | Air trapped in the system; filter not fully flushed; filter nearing end of life. | Flush the system for 5-10 minutes. If the issue persists, the filter may be clogged and require replacement. |
| Unpleasant Taste/Odor | New filter not adequately flushed; filter has reached end of life. | Flush the system for a longer period (up to 15-20 minutes). If taste/odor persists, the filter needs replacement. |
