Installation Steps
The VIOMI RO Water Filtration System is designed for easy DIY installation. Follow these steps for a smooth setup:
Prepare the Installation Area: Clear the under-sink cabinet space. Ensure you have access to a cold water supply line, a drain pipe, and an electrical outlet. Measure your cabinet dimensions to ensure adequate space for the unit (16.3"L x 5"W x 12.8"H).
Install the Faucet: Drill a 1"-1.5" hole in your countertop for the faucet. Insert the faucet and secure it from underneath the sink. Connect the purified water pipe to the faucet.
Connect to Cold Water Supply: Turn off the cold water supply. Install the feed water adapter to the cold water supply valve. Connect the blue pipe from the main unit to this adapter.
Connect to Drain Pipe: Install the drain saddle to the sewer pipe. Connect the gray pipe from the main unit to this saddle.
Connect Power: Plug the power adapter into the main unit and then into a nearby electrical outlet.
Flush the System: Turn on the cold water supply. Open the purified water faucet and let the water run for approximately 20 minutes to flush the system and activate the filters. This ensures optimal performance and taste.

Troubleshooting
If you encounter any issues with your VIOMI RO Water Filtration System, refer to the following common troubleshooting tips:
Slow Water Flow: Check if the filters need replacement (orange light on faucet). Ensure the cold water supply valve is fully open. Verify there are no kinks in the water lines.
Unusual Taste or Odor: This typically indicates that filters need replacement. Flush the system thoroughly after replacing filters.
No Water Dispensing: Check if the unit is properly plugged into a working electrical outlet. Ensure the cold water supply is turned on. Verify that the filter cartridges are correctly installed and locked.
Leakage: Check all connections and ensure they are tightened properly. Inspect O-rings for any damage. If leakage persists, contact customer support.
