Operating Instructions
The Gessi Emporio Via Manzoni basin mixer features a single lever for controlling both water flow and temperature.
- Water Flow: Lift the lever upwards to increase water flow. Push it downwards to decrease or stop the flow.
- Water Temperature: Move the lever to the left for hot water and to the right for cold water. Adjust the position between left and right to achieve the desired temperature.
Maintenance and Care
Regular cleaning and proper maintenance will preserve the finish and functionality of your mixer.
- Cleaning the Finish: Clean the surface with a soft, damp cloth and mild soap. Rinse thoroughly with clean water and dry with a soft cloth to prevent water spots. Do not use abrasive sponges, scouring pads, or chemical cleaners containing alcohol, ammonia, or bleach.
- Aerator Maintenance: Periodically unscrew the aerator at the end of the spout and clean any mineral deposits or debris. Rinse it under running water and reattach it securely.
- Cartridge Maintenance: If the mixer experiences persistent drips or difficulty in controlling flow/temperature, the ceramic cartridge may need inspection or replacement. This should ideally be performed by a qualified plumber.
