Key Specifications
Getting Started
Installation requires a standard 1/8 inch NPT threaded port and Teflon tape or pipe sealant to ensure a leak-proof seal. Electrical connection is made via two screw terminals; ensure the load does not exceed the contact rating (standard 5000 series switches typically support 12VDC systems).
