Why this motor stands out

Built on A.O. Smith’s century-long commitment to reliability, the BN62 carries forward the trusted Century lineage that service professionals and homeowners rely on. The two-speed design is specifically advantageous for spa systems: you can ramp up power for vigorous water circulation during peak use, then shift to a lower speed to reduce energy consumption and prolong component life during quieter periods. The 48Y thru-bolt framing provides a familiar, compatible footprint for many spa housings, making replacement straightforward and downtime minimal.

Ideal for

• Replacements in hot tubs, spa pools, and spa circulation systems
• Upgrading aged spa motors to a more efficient two-speed option
• Service professionals performing standard spa motor swaps
• Residential applications where a compact, reliable 1-phase 230V motor is required

Installation & compatibility

The BN62 is designed for straightforward integration with existing spa equipment that uses a 48Y frame and thru-bolt mounting. With a capacitor mounted on top, it aligns with common spa motor configurations and wired connections for 230V, 1-phase systems. Always refer to the motor’s wiring diagram and ensure proper electrical shutoff and safety precautions during replacement to maintain optimal performance and longevity.

Performance in real-world scenarios

Imagine a spa that experiences daily use during evenings and weekends. With the BN62, you can run a high-speed setting to quickly achieve warm, circulating water after a soak, then switch to low speed to maintain comfortable temperatures with reduced energy draw. For maintenance windows or when running ancillary spa features, the two-speed capability helps manage wear on the pump and related components, contributing to longer service intervals and fewer interruptions.

Maintenance tips

• Keep the motor’s ventilation clear to prevent overheating during extended high-speed operation.
• Verify secure through-bolt mounting and inspect the threaded shaft for any signs of wear during replacements.
• Check the capacitor (top-mounted) as part of routine maintenance to sustain peak efficiency.
