4.1. Pre-Installation Checks

• Confirm water pressure is within the recommended range (check specifications).
• Ensure sufficient space under the sink for the unit and future filter changes.
• Turn off the main water supply before beginning installation.

4.2. Installation Steps (General)

1. Install the Faucet: Drill a hole (if necessary) in the sink or countertop and mount the dedicated drinking water faucet.
2. Connect to Cold Water Supply: Install the water supply adapter to the cold water line under the sink.
3. Install the Drain Saddle: Attach the drain saddle valve to the drain pipe to allow wastewater discharge.
4. Mount the Filter Unit: Place the main filter unit in the desired under-sink location.
5. Connect Tubing: Connect the appropriate tubing from the water supply adapter to the filter inlet, from the filter outlet to the faucet, and from the filter's drain port to the drain saddle.
6. Flush the System: Slowly turn on the water supply. Allow the system to flush for at least 10-15 minutes to remove air and carbon fines. Check for leaks.

5. Operating Instructions

The Aquaphor RO-70S system operates automatically once installed. It uses a multi-stage filtration process to provide clean drinking water.

5.1. Filtration Process

• Pre-filtration: The CarbFiber Block technology in the pre-filters removes organic impurities, heavy metals, and chlorine, filtering particles down to 5 microns. This stage protects the RO membrane.
• Reverse Osmosis Membrane: The RO-50S membrane acts as a barrier against toxic substances, heavy metals, pesticides, bacteria, and viruses, ensuring high-purity water.
• Post-filtration: A final filter polishes the water, improving taste and odor.

5.2. Daily Use

Simply open the dedicated drinking water faucet to dispense purified water. The system will automatically refill the internal tank (if applicable) as water is drawn.

6. Maintenance

Regular maintenance is crucial for the optimal performance and longevity of your Aquaphor RO-70S system. This primarily involves replacing the filter cartridges.

6.1. Filter Replacement

• Pre-filters (K5, K2): Typically replaced every 3-6 months, depending on water quality and usage.
• RO Membrane (RO-50S): Generally replaced every 1-2 years.
• Post-filter (K7B): Typically replaced every 6-12 months.

Always refer to the specific filter replacement schedule provided with your filter cartridges or consult the Aquaphor website for detailed information.

6.2. Replacement Procedure (General)

1. Turn off the water supply to the RO system.
2. Open the faucet to relieve pressure.
3. Remove the old filter cartridges by twisting or unscrewing them (refer to specific filter instructions).
4. Insert new cartridges, ensuring they are properly seated and sealed.
5. Slowly turn on the water supply and check for leaks.
6. Flush the system for several minutes as per initial setup instructions.

7. Troubleshooting

If you encounter issues with your Aquaphor RO-70S system, consult the following common troubleshooting tips.

7.1. Low Water Flow from Faucet

• Clogged Filters: Replace pre-filters or RO membrane if they are past their service life.
• Low Water Pressure: Ensure the incoming water pressure meets the system's requirements.
• Air Lock: Ensure the system has been properly flushed after installation or filter change.

7.2. Unusual Taste or Odor

• Expired Post-filter: Replace the post-carbon filter.
• New System Flush: Ensure the system was adequately flushed during initial setup.
• RO Membrane Failure: If taste issues persist, the RO membrane may need replacement.

7.3. Leaks

• Loose Connections: Check all tubing connections and fittings for tightness.
