Hydrolevel 711CF Low Water Cut-Off
The Hydrolevel 711CF Low Water Cut-Off is a specialized 120Vac control designed for steam boilers, specifically those that lack the direct tappings required for modern Safgard or CycleGard models. This unit mounts directly to gauge glass tappings, utilizing quick hook-up fittings that adapt to sight glasses ranging from 8 to 14 inches. Unlike float-style controls that are prone to mechanical failure due to sediment or scale buildup, the 711CF features a two-probe design with no moving parts in the water. This electronic operation ensures the burner circuit remains energized only when the water level is between the two EL1214 probes. The manifold casting logic provides an automatic reset once water levels are restored, preventing unnecessary boiler short-cycling or water valve slamming caused by a bouncing water line. This robust steam boiler safety control is rated for a maximum pressure of 15 PSI and features SPDT switch contacts for high-reliability performance in demanding residential and light commercial HVACR applications.
Key Benefits- Floatless Technology: Elimination of moving parts prevents mechanical hang-ups caused by lime or scale, significantly reducing emergency service calls.
- Easy Retrofit: Specifically engineered for older boilers; the quick hook-up fittings allow for rapid installation on existing 120V steam systems.
- Precise Level Control: The two-probe manifold maintains a consistent water level, protecting the heat exchanger from dry-firing while managing intermittent level tests.
- Universal Compatibility: Works seamlessly with any standard 120Vac automatic water feeder using integrated dry contacts for secondary control.
- Can I use this on a 24V system? No, the 711CF is a 120Vac model. For 24V applications, the 724CF is the correct technical equivalent.
- Does this include the water feed valve? This is the 'CF' (Cut-Off/Feeder) model which includes the manifold casting and probes but does not include the physical feed valve assembly (#45-711).
- What is the maximum pressure rating? This unit is rated for low pressure steam applications up to 15 PSI.
