AIR CONDITIONER WITH R-410A REFRIGERANT
• 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 in colour.
• R-410A refrigerant cylinders have a dip tube which allows liquid to flow out of the cylinder in upright
position.
• The R-410A units must be charged with refrigerant in a liquid state. 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 the following oils selected by the compressor
manufacturer.
• The vacuum pump is not sufficient to remove moisture from the oil.
• POE oils absorb moisture rapidly. Do not expose oil to atmosphere.
• Never open unit to atmosphere while it is under a vacuum.
• When unit must be opened for service, break vacuum with dry nitrogen and replace filter dryer.
• Do not vent R-410A into the atmosphere.
