Copeland ZPS51K5E-PFV-800 Compressor

When you're spec'ing a 4-ton scroll compressor for a residential or light commercial split system, the Copeland ZPS51K5E-PFV-800 is the industrial standard. As a two-stage modulating compressor, it provides high-efficiency performance by switching between 67% and 100% capacity to match the cooling load precisely. This model is the direct replacement for P032-5122K and P032-5121K, engineered specifically for R410A systems. Operating on 208/230V single-phase power, it features axial and radial compliance, which allows the scroll members to separate under liquid slugging conditions, significantly increasing the HVAC compressor reliability compared to older reciprocating designs. With 70% fewer moving parts and a POE oil charge, this unit is built for contractors who prioritize scroll compressor efficiency and reduced call-backs. The -800 bill of materials includes the 42-inch molded plug wiring harness and mounting hardware to ensure a clean drop-in installation.

• Direct OEM Compatibility: Seamlessly replaces legacy part numbers P032-5122K and P032-5121K without piping re-configurations.
• Two-Stage Modulation: Enhances energy-efficient HVAC performance by reducing cycling and improving humidity control for the end-user.
• Enhanced Durability: Internal inherent protection and a liquid handling design protect the motor from overheating and internal damage.
• Quiet Operation: Precision scroll technology eliminates complex suction and discharge valves, offering a lower decibel rating during high-load operation.
• Simplified Installation: Includes a molded plug wiring harness and mounting kit, reducing the time spent on the roof or at the pad.

What capacitor is required for the ZPS51K5E-PFV-800?
This model typically requires a 40/440 microfarad run capacitor. Always verify the rating on the unit's nameplate during installation.

Can I use this compressor in an R-22 system?
No, the Copeland ZPS51K5E-PFV-800 is specifically designed for R410A refrigerant and utilizes POE oil. Mixing refrigerants or oils will lead to immediate system failure.

Does this unit require a start kit?
Due to the scroll design's ability to start under system load, a start kit is generally not required unless specified by the system manufacturer for low-voltage conditions.
