Heil Quaker ICP 1174407 Pressure Switch
The Heil Quaker ICP 1174407 Pressure Switch is an essential safety component designed for high-pressure monitoring in HVAC refrigeration circuits. This 650/420# high pressure switch is engineered to open the electrical circuit when system pressure reaches 650 PSI, preventing compressor damage, and automatically resets when pressure drops to 420 PSI. As a direct ICP replacement part, it ensures seamless compatibility with Heil, Quaker, Comfortmaker, and KeepRite condensing units. This SPST pressure control features a 1/4-inch SAE female flare nut with a schrader depressor for straightforward installation on the discharge line. Its hermetically sealed construction handles high-vibration environments, maintaining precise setpoints to prevent nuisance tripping while ensuring HVAC system protection. For contractors performing refrigerant pressure safety maintenance, this switch provides the industrial-grade reliability required for demanding cooling cycles.
Key Technical Benefits
- Precise Pressure Calibrations: Factory-set 650 PSI cutout and 420 PSI cut-in points ensure consistent high-side protection.
- Direct OEM Compatibility: Engineered as a drop-in replacement for Heil Quaker part 1174407 to reduce field modification time.
- Durable Construction: Built to withstand high-cycle rates and thermal stress common in residential and commercial condensers.
- Simple Integration: Features standard electrical terminals and a flare fitting for rapid integration into existing control loops.
Common Installation Questions
How do I verify if this switch is the cause of a system lockout?
Technicians should check for continuity across the terminals under normal operating pressures; an open circuit below 420 PSI typically indicates a failed internal diaphragm or contact set.
Does this part require a specific mounting orientation?
While it can be mounted in various positions, it is best practice to install it vertically on the high-side service port to minimize oil logging within the sensor housing.
