Key Features for150S-HD Xylem-McDonnell & Miller Head Mech W/Snap Switch 173003

• Monel Bellows: The unit likely incorporates a Monel bellows for corrosion resistance. Monel is a nickel-copper alloy known for its strength and resistance to corrosion, making it ideal for use in harsh environments such as boilers.
• Maximum Pressure: The head mechanism is likely rated for a maximum pressure of 150 psi (pounds per square inch), which is sufficient for most residential and light commercial boiler applications. (Consult the user manual or datasheet for confirmation).
• Head Mechanism Only: This is just the head (control section) replacement. It does not include the boiler water chamber or other components of the complete low water cut-off and pump controller unit.
• Snap-Action Switches:The head mechanism utilizes snap-action switches for high-temperature service, ensuring reliable operation in the hot environment of a boiler system.

Signs of a Faulty Xylem-McDonnell & Miller 150S-HD Head Mech W/Snap Switch 173003:

• Frequent Boiler Shutdowns: Unexpected or frequent boiler shutdowns could be caused by the head mechanism malfunctioning and triggering a false low water cut-off.
• Pump not Functioning: If the pump control function within the head mechanism malfunctions, the pump might not turn on or might run continuously, disrupting proper water circulation within the boiler system.
• Visible Corrosion on the Head Mechanism: While the head mechanism likely incorporates corrosion-resistant materials, excessive corrosion on the unit's exterior could indicate internal damage or deterioration over time.
