The Sanifount Sensor Operated device is a touchless handwashing system designed for commercial or public use, featuring a sensor-activated water flow and an optional integral electronic soap dispenser. The system is designed for ease of maintenance and troubleshooting, with a modular design that allows for individual component replacement.
Function Description:
The Sanifount system provides a hygienic handwashing experience by activating water flow via a sensor, eliminating the need for physical contact with faucets. This sensor-operated functionality helps reduce the spread of germs and ensures water conservation by dispensing water only when needed. The system is powered by a battery pack, which drives the microprocessor and solenoid valves responsible for water control. An optional integral electronic soap dispenser further enhances the touchless experience by automatically dispensing soap.
Important Technical Specifications:
- Power Source: Battery-Pack (10.8V nominal voltage). The battery pack is designed for easy disconnection and replacement.
- Sensor Type: Infrared sensor for touchless activation. The sensor lens may have a gold opaque shipping cover that needs to be removed during installation.
- Water Control: Solenoid valves manage water flow. These valves are designed to be cleaned or replaced if they become inoperative or jammed.
- Microprocessor: The central control unit for the system, managing sensor input and solenoid valve operation. It features a reset button for system recalibration.
- Connections: Phone jack tabs are used for sensor connections, and screw terminals are used for solenoid valve leads.
- Water Supply: Requires connection to hot and cold water lines, with a thermostatic mixing valve to ensure appropriate water temperature. Strainer screens are present at the entry of the solenoid valves assembly to prevent debris from entering.
- Construction: Features a stainless steel lid on the distribution head, secured by a lock that can be opened with a supplied key.
Usage Features:
- Touchless Operation: Sensors activate water flow, promoting hygiene and reducing germ transmission.
- Automatic Soap Dispensing (Optional): When equipped with an integral electronic soap dispenser, it provides a complete touchless handwashing solution.
- Water Conservation: Water flows only when the sensor is activated, preventing unnecessary water waste.
- Easy Access for Maintenance: The stainless steel lid can be easily removed with a key, providing access to internal components like the battery pack, microprocessor, sensors, and solenoid valves.
- Reset Functionality: A reset button on the microprocessor allows for system recalibration after maintenance or component replacement, ensuring proper operation.
- Troubleshooting Guide: A comprehensive guide is provided to assist users in diagnosing and resolving common issues, such as continuous beeping, insufficient or no water flow, continuous water flow, and repetitive water flow.
Maintenance Features:
- Battery Replacement: The battery pack is easily disconnected and replaced by depressing the terminal lock and pulling the two halves apart. The guide recommends testing the battery for proper 10.8V voltage.
- Sensor Check and Replacement: Sensors can be accessed by removing the distribution head and microprocessor. Defective sensors can be replaced by depressing the phone jack tab and pulling the wire out. The guide suggests swapping sensors between working and non-working positions to diagnose issues.
- Solenoid Valve Maintenance:
- Cleaning: Solenoid valves can be cleaned by separating the electrical and water parts, removing the core and core spring, cleaning them, and then reassembling. This helps address issues like continuous water flow or insufficient flow caused by debris.
- Replacement: If cleaning doesn't resolve the issue, the solenoid valve can be replaced. This involves removing the four screws that secure the coil to the brass water body and then replacing the entire valve.
- Lead Replacement: Solenoid valve leads can also be replaced if they are determined to be faulty. This involves removing screws from the center of the lead and unplugging it from the valve.
- Microprocessor Check and Replacement: If other troubleshooting steps fail, the microprocessor can be checked and replaced. This involves unplugging solenoid valve wires and sensors, unscrewing the four screws and nuts securing the microprocessor, and then replacing it.
- Strainer Screen Cleaning: The guide advises checking and cleaning stop-valve strainer screens and strainer screens at the entry of the solenoid valves assembly to ensure proper water flow.
- Check Valve Cleaning: The check valves on the inlet of the thermostatic mixing valve should also be checked and cleaned.
- Component Pairing: When reinstalling sensors and solenoid wires, it is crucial to ensure that each valve and sensor is paired correctly to its corresponding position on the microprocessor.
- Intersan Parts and Soap: The manual explicitly states that using only Intersan parts for repairs and Intersan soap for units with integral dispensers is necessary to maintain warranty validity.
- Technical Support: Intersan provides technical support via a toll-free number (1-800-999-3101) for issues that cannot be resolved using the provided troubleshooting guide. When contacting support, users should provide information such as the microprocessor's serial number, battery connector color, installation date, environment, and usage patterns.
