General Installation Steps:
- Unpack Components: Carefully remove all items from the packaging and verify against the packing list.
- Mount the System: The main filter unit can be wall/cabinet mounted or freestanding under the sink.
- Install Faucet: Mount the included fast-flow faucet on your sink or countertop.
- Connect Water Supply: Connect the system to your cold water line using the provided fittings.
- Connect Drain Line: Install the drain saddle valve on your sink's drain pipe.
- Connect Storage Tank: Place the 4-gallon storage tank (3.2-gallon water capacity) and connect it to the system.
- Install Leak Stop Valve: Position the emergency leak stop detector on the cabinet floor where it can detect moisture.
- Flush the System: Follow the initial flushing procedure outlined in the detailed manual to prepare the system for use and remove any manufacturing residues. This typically involves filling and draining the tank multiple times.

How the 5-Stage Filtration Works:

- Stage 1: Sediment Filter (SED)
Reduces dirt, dust, sand, and rust particles. - Stage 2 & 3: Granular Activated Carbon (GAC) & Activated Carbon Block (ACB) Filters
Reduces chlorine, volatile organic chemicals (VOCs), and odor-causing compounds. These stages protect the RO membrane. - Stage 4: Reverse Osmosis Membrane (ROM)
The core of the system, reducing up to 99.99% of difficult impurities like lead, arsenic, chromium, fluoride, TDS, and radium. - Stage 5: Post Activated Carbon Filter (PAC)
Provides a final polish to the water just before it reaches the faucet, removing any residual tastes or odors.
The system continuously monitors the water level in the storage tank and refills it as needed, ensuring a constant supply of purified water.
Maintenance
Regular maintenance, primarily filter replacement, is crucial for the optimal performance and longevity of your RO system.

Filter Replacement Schedule:
- Sediment, GAC, and ACB Filters (Stages 1, 2, 3): Replace approximately every 6-12 months, depending on water quality and usage. Your system includes an extra set of these filters for the first year of use.
- Reverse Osmosis Membrane (Stage 4): Replace approximately every 24 months (2 years), depending on water quality and usage.
- Post Activated Carbon Filter (Stage 5): Replace approximately every 6-12 months, typically along with the pre-filters.
Always use genuine Express Water replacement filters to ensure compatibility and performance. Refer to the Instructions for Use (IFU) PDF for detailed filter replacement procedures.
Leak Detection System:
The integrated leak stop detector is a safety feature. If it detects moisture, it will automatically shut off the water supply to the system. If this occurs, inspect all connections for leaks, tighten as necessary, and reset the leak detector.
