1. Introduction
The Zurn P6900-B-L AquaSense Electronics Module with Solenoid is a replacement component designed for Zurn AquaSense sensor faucets, specifically models Z6912, Z6913, Z6915, and Z6920. This module integrates the solenoid valve, battery pack, and the necessary wiring to connect to the faucet's infrared proximity sensor, enabling hands-free operation. This manual provides instructions for proper installation, operation, and maintenance of the module.
2. Safety Information
- Always turn off the water supply to the faucet before beginning any installation or maintenance.
- Disconnect electrical power if applicable before servicing.
- Wear appropriate personal protective equipment, such as safety glasses and gloves.
- Ensure all connections are secure to prevent leaks.
- Dispose of old batteries responsibly according to local regulations.
3. Package Contents
Verify that all components are present before beginning installation:
- Zurn P6900-B-L AquaSense Electronics Module with Solenoid
- Battery Pack (integrated)
- 4 AA Alkaline Batteries (included)
- Connecting Wire to Faucet Sensor
- Small Hex Key/Wrench (for securing connections, if applicable)
- O-ring (for sealing connections, if applicable)
4. Setup and Installation
Follow these steps to install the Zurn P6900-B-L Electronics Module:
- Turn Off Water Supply: Locate the main water shut-off valve for the faucet and turn it off completely.
- Disconnect Old Module (if replacing): Carefully disconnect the existing electronics module from the faucet sensor and water lines. Be prepared for residual water.
- Prepare New Module: Ensure the new P6900-B-L module has the included 4 AA alkaline batteries properly installed in the battery compartment.
- Connect Water Lines: Attach the solenoid valve portion of the new module to the appropriate hot and cold water supply lines. Use thread sealant tape or pipe dope as recommended by local plumbing codes. Ensure connections are hand-tight, then use a wrench for a final quarter-turn, avoiding overtightening.
- Connect Sensor Wire: Carefully connect the wire from the electronics module to the faucet's infrared proximity sensor. The connector pins are delicate; align them precisely to avoid bending. Removing any rubber o-ring on the connector might assist in feeling for a solid connection, as a coupler nut typically secures the pieces.
- Secure Module: Mount or secure the electronics module in a suitable location, typically under the sink, ensuring it is protected from moisture and easily accessible for future maintenance.
- Restore Water Supply: Slowly turn the main water supply back on and check for any leaks at all connection points.
- Test Operation: Activate the faucet sensor to verify proper water flow and shut-off.
5. Operating Instructions
The Zurn AquaSense Electronics Module controls water flow in conjunction with the faucet's infrared proximity sensor. To operate the faucet:
- Activation: Place your hands within the detection range of the faucet's sensor. The sensor will detect your presence.
- Water Flow: Upon detection, the electronics module will activate the solenoid valve, allowing water to flow from the faucet.
- Deactivation: Remove your hands from the sensor's detection range. The module will then close the solenoid valve, stopping the water flow.
The system is designed for hands-free operation, promoting hygiene and water conservation.
6. Maintenance
Regular maintenance ensures optimal performance and longevity of your Zurn AquaSense Electronics Module.
6.1. Battery Replacement
The module is powered by 4 AA alkaline batteries. When the batteries are low, the faucet may exhibit inconsistent operation or cease to function. To replace the batteries:
- Turn Off Water Supply: Turn off the water supply to the faucet.
- Access Battery Compartment: Locate the battery compartment on the electronics module. This is typically secured with a cover.
- Remove Old Batteries: Open the compartment and remove the old AA batteries.
- Insert New Batteries: Insert four new AA alkaline batteries, ensuring correct polarity (+/-).
- Secure Compartment: Close and secure the battery compartment cover.
- Restore Water Supply and Test: Turn the water supply back on and test the faucet's operation.
6.2. Cleaning
Periodically inspect the module and connections for any signs of corrosion or debris. Clean the exterior of the module with a soft, damp cloth. Do not use abrasive cleaners or solvents.
7. Troubleshooting
If your Zurn AquaSense faucet is not functioning correctly, refer to the following table for common issues and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No water flow when sensor is activated | Low or dead batteries Water supply off Sensor wire disconnected or damaged Solenoid valve malfunction | Replace batteries Check water supply valve Verify sensor wire connection Contact Zurn support for solenoid replacement |
