3. Setup and Installation

The iFilters RO-550 system is designed for under-sink installation. Professional installation is recommended, but if you choose to install it yourself, follow these general steps. Refer to the detailed installation guide included in your package for specific diagrams and instructions.

Pre-Installation Checklist:

• Verify all components are present and undamaged.
• Ensure you have the necessary tools (drill, wrench, Teflon tape, etc.).
• Locate a suitable under-sink area with access to cold water line, drain, and space for the storage tank and faucet.
• Turn off the main cold water supply before beginning installation.

General Installation Steps:

1. Install the Faucet: Drill a hole in the sink or countertop (if not pre-drilled) and mount the chrome faucet. Secure it with the provided hardware.
2. Connect the Feed Water Adapter: Turn off the cold water supply. Disconnect the cold water line from the existing faucet. Install the feed water adapter valve onto the cold water supply line. Reconnect the cold water line to the adapter.
3. Install the Drain Saddle: Attach the drain saddle to the drain pipe under the sink, ensuring it is above the P-trap. Drill a hole through the drain pipe at the saddle location.
4. Mount the RO Unit: Secure the main RO filter unit to the cabinet wall using the provided mounting bracket and screws.
5. Connect Tubing:
   • Connect the feed water line from the adapter to the inlet of the RO unit.
   • Connect the purified water line from the RO unit to the storage tank.
   • Connect the waste water line from the RO unit to the drain saddle.
   • Connect the purified water line from the storage tank to the RO faucet.
6. Install the Storage Tank: Place the storage tank in a suitable location under the sink. Connect the tank valve to the tank and then to the RO unit.
7. Leak Check: Slowly turn on the main cold water supply. Check all connections for leaks. Tighten any leaking connections.

4. Operating Instructions

Initial System Start-up and Flush:

1. After installation, ensure all connections are tight and the water supply is on.
2. Open the RO faucet and leave it open until water begins to drip, then close it.
3. Allow the storage tank to fill completely (this may take 2-3 hours depending on water pressure).
4. Once the tank is full, open the RO faucet and let all the water drain out. This flushes out carbon fines and air from the system.
5. Repeat steps 3 and 4 at least two more times. This ensures the system is properly flushed and ready for use.

Daily Operation:

The iFilters RO-550 system operates automatically. When you open the RO faucet, purified water will flow from the storage tank. As water is drawn, the system will automatically produce more purified water to refill the tank.

5. Maintenance

Regular maintenance, primarily filter replacement, is crucial for the optimal performance and longevity of your RO system. Filter changes are designed to be simple and tool-free.

Filter Replacement Schedule:

Filter Replacement Procedure:

1. Turn off the cold water supply to the RO system and close the tank valve.
2. Open the RO faucet to relieve pressure in the system.
3. Carefully unscrew the filter housings for stages 1, 2, and 3.
4. Remove and discard the old filters. Clean the housings with mild soap and water.
5. Insert new filters, ensuring they are correctly oriented.
6. Screw the housings back on, hand-tightening them.
7. For the RO membrane (Stage 4) and Post GAC filter (Stage 5), follow the specific instructions provided with your replacement filters, as these may involve quick-connect fittings.
8. Slowly turn on the cold water supply and open the tank valve. Check for leaks.
9. Perform an initial system flush as described in the "Initial System Start-up and Flush" section.

6. Troubleshooting

This section addresses common issues you might encounter with your iFilters RO-550 system.

Common Issues and Solutions:

• No Water Flow from Faucet:
  • Check if the cold water supply to the RO system is turned on.
  • Ensure the storage tank valve is open.
  • Verify the storage tank has sufficient pressure (check air pressure if necessary).
  • Check for clogged filters or a clogged RO membrane. Replace if needed.
• Slow Water Production:
  • Low incoming water pressure.
  • Clogged pre-filters or RO membrane.
  • Low temperature of incoming water.
  • Air bladder in the storage tank needs repressurizing.
• Unpleasant Taste or Odor:
  • Post-carbon filter needs replacement.
  • RO membrane may be compromised (rare, but possible if filters are not changed regularly).
  • System was not properly flushed after installation or filter change.
• Leaks:
  • Inspect all connections and fittings. Tighten any loose connections.
  • Ensure O-rings are properly seated in filter housings.
