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).
