AIR CONDITIONER WITH R-410A - QUICK REFERENCE GUIDE
• R-410A refrigerant operates at 50%-70% 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 pink.
• R-410A refrigerant cylinders have a dip tube which allows liquid to flow out with the cylinder in a vertical
position with the valve at the top.
• R-410A systems should be charged with liquid refrigerant. Use a commercial type metering device
in the manifold hose in order to vaporize the liquid refrigerant before it enters in the unit.
• R-410A, as other HFCs, is only compatible with oils selected by the compressor manufacturer.
• A vacuum pump is not enough to remove moisture from oil.
• Oils absorb moisture rapidly. Do not expose oil to atmosphere.
• Never open system to atmosphere while it is under vacuum.
• When the system must be opened for service, break vacuum with dry nitrogen.
• Do not vent R-410A into the atmosphere.
• Use only Carrier matching indoor units and outdoor units (Table I).
