Daikin-McQuay 332562001 Switch Kit

The Daikin-McQuay 332562001 Switch Kit is a field-proven assembly designed to maintain the mechanical integrity and operational safety of complex chiller and compressor systems. This dual-purpose kit integrates a high-precision oil differential pressure switch and a vane air switch, providing critical protection against low oil lubrication and airflow irregularities. In large-scale HVACR applications, the oil differential component monitors the pressure drop across the oil pump to prevent bearing failure, while the vane switch verifies proper discharge or suction flow. As an OEM Daikin-McQuay replacement part, this kit ensures seamless integration into existing control circuits, maintaining factory-specified safety parameters. This kit is a direct replacement for legacy part numbers, including 070180512 and 350A061H12, making it a versatile solution for urgent service calls and preventative maintenance. When replacing HVAC compressor safety switches, utilizing original equipment manufacturer components is necessary to ensure voltage compliance and set-point accuracy across various commercial HVAC systems and industrial chillers.

• System Protection: Actively prevents catastrophic compressor damage by triggering an automatic shutdown if oil pressure falls below safe operating levels.
• OEM Compatibility: Specifically engineered as a genuine Daikin 332562001 switch kit, ensuring perfect fitment and reliable electrical termination.
• Multi-Switch Integration: Combines both oil differential and vane air monitoring into a single service kit for comprehensive system oversight.
• High Durability: Constructed with industrial-grade materials to withstand the high-vibration and pressure-variable environments of semi-hermetic compressors.

• How does the oil differential switch protect the unit? It measures the difference between oil pump discharge pressure and crankcase pressure; if this differential is insufficient for proper lubrication, the switch opens the safety circuit.
• Is this kit compatible with older McQuay chillers? Yes, the 332562001 is the current HVAC part replacement for several discontinued numbers, including 350A978G67 and 735006112.
• What is the function of the vane switch in this assembly? The vane switch acts as a flow sensor, typically verifying airflow or refrigerant movement to ensure the system is operating within its thermal design limits.
