2. Setup and Installation
This section provides detailed instructions for installing your Ecoviva E8 RO system. Professional installation is recommended if you are not comfortable with plumbing or drilling.
Before You Begin:
- Space Requirements: Ensure a minimum clearance of 12.2" (H) x 5.0" (W) x 16.54" (L) under your sink. Leave 2-4 inches around pipe connections for maintenance.
- Electrical Outlet: An under-sink power outlet (AC110-120V/60Hz 85W) is required.
- Water Supply: Connects to municipal tap water.
- Countertop Hole: A 24-35mm hole is required for the dedicated smart faucet. A drilling guide sticker is included.
- Included Components: Verify all parts are present: RO System (with pre-installed PPC and RO filters), Smart Faucet, Installation Kit (tubing, fittings), User Manual.

Installation Steps:
- Prepare the Faucet Hole: If a hole is not present, drill a 24-35mm hole in your countertop or sink for the smart faucet.
- Install the Smart Faucet: Insert the faucet into the drilled hole and secure it from underneath the sink using the provided hardware. Connect the water lines and electrical cable from the faucet to the main RO unit.
- Connect Water Supply: Turn off the cold water supply. Install the provided T-adapter to your cold water line and connect the system's input water line (usually blue) to the T-adapter.
- Connect Drain Line: Attach the drain saddle to the drain pipe under your sink. Connect the system's drain line (usually red) to the drain saddle.
- Place the RO Unit: Position the Ecoviva E8 unit under the sink, ensuring it is level and has adequate clearance.
- Connect Power: Plug the RO system into a grounded electrical outlet.
- Initial Flush: Turn on the cold water supply. Open the smart faucet and let the water run for approximately 30 minutes to flush the system and new filters. This removes air and carbon fines.

Smart Faucet Display:
The integrated LED smart faucet provides real-time information about your water quality and filter status.
- Real-Time TDS Monitor: The display shows the current TDS (Total Dissolved Solids) level of the filtered water. A lower TDS reading indicates higher water purity.
- Filter Life Reminder: The faucet will indicate the status of your PPC and RO filters, reminding you when it's time for replacement.

4. Maintenance
Regular maintenance, primarily filter replacement, ensures optimal performance and water quality from your Ecoviva E8 system.
Filter Replacement:
The Ecoviva E8 uses two main filters: the PPC (Pre-Carbon Block & PP Cotton) filter and the RO (Reverse Osmosis Membrane & Carbon Block & PP Cotton) filter. The smart faucet will indicate when replacement is needed.
- PPC Filter Life: Approximately 12 months.
- RO Filter Life: Approximately 24 months.

Steps for Filter Replacement:
- Turn off the water supply to the RO system.
- Unplug the power cord from the electrical outlet.
- Locate the filter(s) to be replaced. The filters are designed for tool-free replacement.
- Twist the old filter counter-clockwise and pull it out.
- Insert the new filter, aligning it correctly, and twist clockwise until it locks into place.
- Plug in the power cord and turn on the water supply.
- Flush the new filter by running water from the smart faucet for 5-10 minutes.

5. Troubleshooting
This section addresses common issues you might encounter with your Ecoviva E8 RO system. For problems not listed here, please contact customer support.
| Problem | Possible Cause | Solution |
|---|---|---|
| No water from faucet | Water supply off, power off, clogged filters, faucet not connected properly. | Check water supply valve. Ensure unit is plugged in. Check filter status on smart faucet and replace if needed. Ensure smart faucet is securely connected to the main unit. |
| Low water flow | Clogged filters, low incoming water pressure. | Replace filters. Ensure adequate incoming water pressure (refer to specifications). |
| High TDS reading | RO filter needs replacement, system not flushed properly. | Check RO filter status on smart faucet and replace if indicated. Ensure initial flush was completed for 30 minutes. |
| Leakage | Loose connections, damaged O-rings or tubing. | Tighten all connections. Inspect O-rings and tubing for damage and replace if necessary. |
| System not making water (faucet feedback needed) | Smart faucet not properly connected or communicating with the main unit. | Ensure the smart faucet's electronic connection to the main unit is secure. The system requires electronic feedback from the spigot to operate. |
