McDonnell & Miller FPC-1000-P Low Water Cut-Off Control 24V/120V Steam/Hot Water

The McDonnell & Miller FPC-1000-P (Model 144705) is a versatile low water cut-off control designed to protect steam and hot water boilers from operating with insufficient water levels. This multi-voltage unit accepts either 24V or 120V power input, making it adaptable to various system configurations.

Key Features:

• Dual voltage operation: 24V or 120V compatibility for installation flexibility
• Suitable for both steam and hot water boiler applications
• Selectable automatic or manual reset functionality
• Proven McDonnell & Miller float technology for reliable water level detection
• Prevents dangerous low water conditions that can cause boiler damage
• External test lever for convenient system verification

This low water cut-off control automatically shuts down the boiler when water levels drop below the safe operating point, protecting against costly damage from dry firing. The unit mounts directly to the boiler and uses a float mechanism to accurately monitor water levels. The manual reset option ensures that low water conditions are investigated before restart, while automatic reset mode provides hands-free operation for systems with monitoring personnel.
