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 of cylinder in an upright
position.
• 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.
• LR-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.
• POE oils absorb moisture rapidly. Do not expose oil to atmosphere.
• Never open system to atmosphere while it is under vacuum.
• In case the system should be opened for maintenance, stop the vacuum function with dry nitrogen and
replace the drier filters, if any.
• Do not vent R-410A into the atmosphere.
• Use only Carrier matching indoor units (Table I).
