5. Operating Instructions
The Gerber Viper Faucet features a single lever handle for controlling both water temperature and flow. To operate:
- Turn On/Off: Lift the handle to turn on the water. Push the handle down to turn off the water.
- Adjust Water Flow: The height to which the handle is lifted controls the water flow rate. Lift higher for more flow, lower for less.
- Adjust Water Temperature: Swivel the handle left for hot water and right for cold water. The ceramic disc cartridge ensures smooth and precise temperature adjustments.
This faucet is equipped with laminar flow aeration, which provides a clear, steady stream of water, reducing splashing and maintaining a clean bathroom environment.

6. Maintenance
To maintain the finish and performance of your Gerber Viper Faucet, follow these guidelines:
- Regular Cleaning: Clean the faucet regularly with a soft cloth and warm, soapy water. Rinse thoroughly and dry with a soft cloth to prevent water spots.
- Avoid Harsh Cleaners: Do not use abrasive cleaners, scouring pads, or chemical cleaners containing ammonia, bleach, or alcohol, as these can damage the finish.
- Aerator Cleaning: If water flow decreases, the aerator may be clogged. Unscrew the aerator from the spout, clean any debris or mineral deposits, and reattach.
- Check for Leaks: Periodically inspect connections for any signs of leaks and tighten if necessary.
