3. Installation Guide
This section provides step-by-step instructions for replacing your water filter cartridge. Always refer to your specific Rainsoft® Hydrefiner system manual for detailed instructions, as procedures may vary slightly.
Before You Begin:
- Ensure you have the correct replacement cartridge (Neo-Pure NP-P12 PLUS).
- Locate the water supply shut-off valve for your drinking water system.
- Have a bucket or towel ready to catch any residual water.
- It is recommended to wear gloves for hygiene.
Installation Steps:
- Turn Off Water Supply: Locate the cold water supply line to your drinking water system and turn off the shut-off valve.
- Relieve Pressure: Open the dedicated filtered water faucet to relieve any pressure in the system. Allow water to drain until it stops.
- Remove Old Cartridge: Carefully twist the old filter cartridge counter-clockwise to unlock it from the filter head. Some water may spill, so have your bucket or towel ready.
- Dispose of Old Cartridge: Discard the old filter cartridge according to local regulations.
- Prepare New Cartridge: Remove the new Neo-Pure NP-P12 PLUS cartridge from its packaging. Ensure the O-rings are properly seated.
- Install New Cartridge: Insert the new cartridge into the filter head, aligning the tabs on the cartridge with the slots in the head. Twist clockwise until it locks securely into place. Do not overtighten.
- Restore Water Supply: Slowly turn on the cold water supply shut-off valve.
- Flush the System: Open the filtered water faucet and allow water to run for at least 5-10 minutes to flush out any carbon fines and air from the system. The water may appear cloudy initially; this is normal and will clear up.
- Check for Leaks: Inspect all connections for any leaks. If leaks are present, ensure the cartridge is properly seated and tightened.
