while the second switch serves as a high-limit safety to shut down the burner or compressor at 3/8-inch below the waterline

ensuring operational reliability in demanding environments

preventing premature motor failure and optimizing system efficiency

Utilizing the York S1-025-31885-000 during routine service or after a compressor swap-out prevents voltage drops and circuit resistance that can lead to premature motor burnout

Reznor 136965 Venter 318172-701 while the second switch servesThe Reznor 136965 is a high performance CA1 venter assembly designed specifically for large scale Reznor unit heaters, providing critical motor driven exhaust for systems between 350,000 and 400,000 BTUh. This 115V single phase power assembly operates as a motorized exhauster, ensuring safe dilution of flue gases in environments with negative pressure or where horizontal venting is required. The integrated 24V relay acts as a safety barrier, isolating
