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.
• The R-410A, as for other HFC, is only compatible with oils chosen by the compressor manufacturer.
For this reason, for the type of oil to be used, always refer to the plate on the compressor and the unit.
• 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).
