Watts 0226080 Low Water Cut Off

As a veteran tech, you know that keeping a steam boiler safe means having a reliable low water cut-off you can trust. The Watts 0226080, specifically the SAN89S model, is a heavy-duty float and switch assembly designed for rapid field servicing without disturbing your existing pipework. This single switch assembly features a rugged SPST switch (Single Pole Single Throw) configuration, making it the industry standard for 15 psi steam applications where a consistent burner shut-off is non-negotiable.

The Watts SAN89S is engineered with a unique one-piece construction that ensures all factory adjustments remain intact during the swap. Whether you are dealing with a hydronic heating system or a standard low pressure steam boiler, this unit fits gauge glass connections perfectly, providing an essential safety barrier against "dry fire" conditions. With a maximum working pressure of 15 psi, it is the go-to replacement float assembly for contractors who prioritize boiler safety and minimal downtime on the job site.

• Streamlined Installation: The one-piece float and switch design allows for a quick drop-in replacement, saving you time on service calls.
• Universal Compatibility: Designed specifically for Series SAN89 servicing, ensuring a perfect fit for 15 psi steam pressure systems.
• Technical Reliability: Features a high-quality SPST switch for precise burner control when water levels reach critical thresholds.
• No Pipe Disturbance: Replace the internal assembly without having to re-pipe the float chamber or the gauge glass.

Is the Watts 0226080 compatible with millivolt systems?
Yes, the SAN89S switch is suitable for millivolt service in self-energized control circuits of gas-fired installations, providing versatility for various older and modern setups.

What is the maximum operating pressure for this unit?
This specific low water cut-off assembly is rated for a maximum operating pressure of 15 psi (103 kPa), making it ideal for residential and light commercial steam boilers.

Can I use this to replace a dual-switch model?
The SAN89S is a single switch model. If your current application requires an auxiliary alarm or motor starter circuit in addition to the burner cutoff, verify if the SAN89D dual switch assembly is required for your specific wiring needs.
