The Lennox Y8809 Supco SPR1 Ultra Start Hard Start Kit is designed to improve compressor startup reliability by delivering a brief boost of starting torque. It combines a high-quality start capacitor with a solid-state potential relay, allowing the compressor to start quickly and smoothly while automatically removing the capacitor from the circuit after startup.

This hard start kit is ideal for service replacements, preventive maintenance, and system upgrades where compressors experience hard starting, breaker tripping, or delayed startup. It is compatible with most 3.5 to 5 HP single-phase compressors operating within the specified voltage range.

 

Key Benefits:

Improves compressor starting torque
Helps prevent nuisance breaker trips and voltage drop issues
Reduces mechanical and electrical stress on the compressor
Solid-state relay design for reliable operation
Quick and easy installation for HVAC service professionals
Suitable for residential and light commercial applications
