R-410A QUICK REFERENCE GUIDE

Refer to Installation Instructions for specific installation requirements.

R-410A Refrigerant operates at 50 - 70 percent higher pressures than R-22. Be sure that servicing equipment and replacement components are designed to operate with R-410A.

R-410A Refrigerant cylinders are rose colored.

Recovery cylinder service pressure rating must be 400 psig, DOT 4BA400, or DOT BW400. Recovery equipment must be rated for R-410A.

Do Not use R-410A service equipment on R-22 systems. All hoses, gages, recovery cylinders, charging cylinders and recovery equipment must be dedicated for use on R-410A systems only.

Manifold sets must be at least 700 psig high side, and 180 psig low side, with 550 psig retard. All hoses must have a service pressure rating of 800 psig.

Leak detectors must be designed to detect HFC refrigerants.

Systems must be charged with liquid refrigerant. Use a commercial type metering device in the manifold hose.

R-410A can only be used with POE type oils.

POE type oils rapidly absorb moisture from the atmosphere. Vacuum pumps will not remove moisture from POE type oils.

Do not use liquid line driers with a rated working pressure rating less than 600 psig.

Do not install suction line driers in the liquid line.

A liquid line drier is required on every unit.

Do not use a R-22 TXV. If a TXV is to be used, it must be a R-410A TXV. Never open system to atmosphere when under a vacuum.

If system must be opened for service, evacuate system then break the vacuum with dry nitrogen and replace all filter driers.

R-410A specifications

York R-410A is a widely recognized and highly efficient refrigerant used in modern air conditioning systems. Developed as an environmentally friendly alternative to R-22, R-410A has gained popularity in the HVAC industry due to its numerous advantageous features and characteristics.

One of the main features of York R-410A is its ability to provide superior cooling performance. This refrigerant operates efficiently at both high and low temperatures, allowing systems using it to maintain optimal indoor climates even during extreme weather conditions. Its high energy efficiency ratio (EER) and seasonal energy efficiency ratio (SEER) ratings make it a preferred choice for energy-conscious consumers, resulting in lower energy bills and a reduced carbon footprint.

Technologically, York R-410A systems feature advanced compressor designs that enhance their overall reliability and performance. These compressors are often equipped with variable-speed technology, enabling them to adjust their output to match the cooling demands of the space. This not only improves comfort levels but also leads to efficient energy consumption, reducing wear and tear on the equipment over time.

Another significant characteristic of York R-410A is its non-ozone-depleting properties. Unlike its predecessor R-22, which is being phased out due to its damaging effects on the ozone layer, R-410A is designed to minimize environmental impact. Its lower global warming potential (GWP) further underscores its role in promoting sustainability within the HVAC sector.

Furthermore, York R-410A systems are engineered with enhanced safety features. The refrigerant is non-toxic and non-flammable, which makes it safer for use in both residential and commercial applications. Additionally, its high thermal stability reduces the risk of breakdown or leakage, contributing to longer system lifespans and lower maintenance costs.

In conclusion, York R-410A stands out as a cutting-edge refrigerant that combines efficiency, safety, and environmental responsibility. With its advanced technologies and remarkable characteristics, it meets the demands of modern air conditioning requirements while paving the way for a sustainable future in HVAC systems. Adopting York R-410A not only benefits individual users through improved comfort and lower energy bills but also plays a vital role in protecting our planet's ozone layer and mitigating climate change.
