Introduction
This Naturewater NW-3RO-190 3-stage reverse osmosis system provides purified water by removing up to 99% of contaminants such as heavy metals, pesticides, hormones, and bacteria. With a flow rate of 190 liters per day, it ensures effective filtration for superior quality drinking water.
The system utilizes a semi-permeable membrane to retain impurities, allowing only pure water to pass through. Combined with sediment and activated carbon filters, it eliminates chlorine, limescale, nitrates, and chemical substances, resulting in cleaner water without unpleasant tastes.
Designed for easy and quick installation, this water purifier comes with detailed instructions, allowing setup in approximately 20 minutes. It is suitable for domestic and professional use, including drinking water, aquariums, or demineralized water production.
Setup Guide
Unpacking and Components
Carefully unpack all components from the box. Ensure the following items are present:
- Filter wrench
- Activated carbon filter
- Connection tubes
- 5-micron PP ultra-fine filter
- Mounting and connection accessories
- High-performance 50 GPD membrane
Installation Steps
- Choose Location: Select a suitable location for installation, either under the sink or wall-mounted. Ensure there is enough space for maintenance and filter replacement.
- Connect Water Supply: Identify the red-coded connector for the water supply line. Connect it to your cold water line using the provided three-way adapter and ball valve.
- Connect Drainage: Identify the black-coded connector for the drainage line. Connect it to the drain pipe using the saddle valve provided.
- Connect Faucet: Identify the blue-coded connector for the purified water line. Connect this line to the dedicated RO faucet.
- Install Filters and Membrane: Insert the PP sediment filter, activated carbon filter, and RO membrane into their respective housings. Ensure proper orientation as indicated on the filters. Use the filter wrench to tighten the housings securely, but do not overtighten.
- Check for Leaks: Slowly turn on the main water supply. Inspect all connections for any leaks. Tighten any leaking connections as needed.
Operation
Initial System Flush
Before consuming water from the system for the first time, it is crucial to flush the system. Open the RO faucet and let the water run for at least 15-30 minutes. This removes air from the system and flushes out any carbon fines from the new filters. The initial water may appear cloudy or discolored; this is normal.
Filtration Process
The Naturewater NW-3RO-190 system employs a three-stage filtration process:
- Stage 1: PP Sediment Filter - Removes larger particles such as sand, dirt, rust, and silt, protecting subsequent filters.
- Stage 2: Activated Carbon Filter - Absorbs chlorine, organic chemicals, pesticides, herbicides, and other contaminants that cause bad taste and odor.
- Stage 3: Reverse Osmosis Membrane - The core of the system, this semi-permeable membrane removes up to 99% of dissolved solids, heavy metals, bacteria, viruses, and other microscopic impurities.
Daily Use
Once installed and flushed, the system operates automatically. Simply open the dedicated RO faucet to dispense purified water for drinking, cooking, or other uses. The system will produce water as long as the main water supply is on and pressure is sufficient.
Maintenance
Filter Replacement Schedule
Regular filter replacement is essential to maintain optimal performance and water quality. The recommended replacement intervals are:
- PP Sediment Filter (Stage 1): Every 3-6 months, depending on incoming water quality and usage.
- Activated Carbon Filter (Stage 2): Every 6-12 months, depending on incoming water quality and usage.
- RO Membrane (Stage 3): Every 1-2 years, or when water quality significantly degrades (e.g., increased TDS levels).
Filter Replacement Procedure
- Turn Off Water Supply: Locate the ball valve on the water supply line to the RO system and turn it off.
- Depressurize System: Open the RO faucet to release any pressure in the system.
- Remove Filter Housings: Use the provided filter wrench to unscrew the filter housings counter-clockwise.
- Remove Old Filters: Carefully remove the old filters and dispose of them properly.
- Insert New Filters: Place new filters into their respective housings, ensuring they are correctly seated and oriented.
- Reattach Housings: Screw the filter housings back on clockwise. Hand-tighten first, then use the filter wrench for an additional quarter turn to ensure a snug, leak-free seal. Do not overtighten.
- Restore Water Supply: Slowly turn on the main water supply to the RO system.
- Check for Leaks: Monitor all connections for any leaks. Tighten as necessary.
- Flush System: Open the RO faucet and flush the system for 10-15 minutes to remove any air and new filter residue before consuming water.
Troubleshooting
This section addresses common issues you might encounter with your Naturewater NW-3RO-190 system.
| Problem | Possible Cause | Solution |
|---|---|---|
| Low Water Flow from Faucet | Clogged pre-filters (sediment or carbon) Low incoming water pressure Fouled RO membrane | Replace sediment and/or carbon filters Check household water pressure Replace RO membrane |
| Water Leaking | Loose connections Damaged O-rings Cracked housing | Tighten all fittings and filter housings Inspect and replace O-rings Contact customer support for replacement parts |
| Poor Water Quality (e.g., bad taste, high TDS) | Exhausted RO membrane Bypass in filtration stages Contaminated post-filter (if applicable) | Replace RO membrane Ensure all connections are correct and sealed Replace post-filter |
| No Water Production | Water supply turned off Kinked tubing Closed valves | Ensure main water supply is on Check and straighten all tubing Verify all system valves are open |
