Specifications:
The S3 Series Automatic Bilge Switches, Part No. 4801 and 4802, are designed for marine applications to automatically control bilge pumps. They are engineered to activate the pump when water levels reach a certain height and deactivate it once the water is expelled.

Procedures:
Installation involves connecting the switch to the bilge pump and ensuring it is securely mounted at the correct height for optimal operation. Regular testing is recommended to ensure functionality.

Standards:
The switches comply with marine safety standards, ensuring reliability and durability in harsh marine environments.

Recommendations:
It is advised to periodically inspect the switches for debris or damage that could impede performance. Ensure electrical connections are secure and free from corrosion.

Key Data from Tables/Graphs:
The technical document includes performance graphs showing activation and deactivation water levels, as well as electrical specifications such as voltage and current ratings. These indicate the switch's capability to handle various bilge pump capacities.
