Daikin-McQuay 073074002 Pressure Switch
The Daikin-McQuay 073074002 High Pressure Switch is an essential safety component designed for precise HVAC pressure monitoring and compressor protection. This SPST (Single Pole Single Throw) encapsulated switch is engineered to open the control circuit when system pressures exceed safe operating parameters, specifically calibrated for a 400 PSI cutout and a 300 PSI reset. Built for durability in high-vibration environments, the 073074002 ensures reliable refrigerant pressure control across a wide range of commercial McQuay chiller parts and rooftop unit applications. The hermetically sealed design prevents moisture ingress and contact oxidation, which is common in industrial HVAC maintenance. By preventing the system from operating under excessive head pressure, this DAIKIN pressure switch replacement protects the compressor motor from thermal overload and mechanical failure. This OEM pressure switch features a standard 1/4" female flare fitting for secure attachment to the high-side service port.
Key Benefits for Technicians- Precise Pressure Calibration: Accurate 400# high-side trip and 300# automatic reset minimize system downtime while ensuring safety.
- Encapsulated Design: Environmental sealing allows for reliable performance in extreme ambient temperatures and high-humidity conditions.
- Direct Fit Compatibility: Specifically engineered for Daikin-McQuay 073074002 replacement, ensuring zero modification is required during installation.
- Enhanced System Reliability: Acts as a critical failsafe to prevent refrigerant high pressure damage to the compressor.
Is the 073074002 an automatic or manual reset switch?
This model features an automatic reset functionality, closing the circuit once the high-side pressure drops back down to the 300 PSI threshold.
What refrigerant types is this high pressure switch compatible with?
It is designed for use with standard high-pressure refrigerants common in Daikin-McQuay commercial systems, including R-22 and R-410A applications where the 400 PSI limit is required.
What is the connection type for this HVAC pressure switch?
The unit utilizes a standard internal Schrader-compatible depressor and a 1/4" female SAE flare nut for quick mechanical connection.
