4/23/2014 The ozone is only part of the equation in refrigerant containment andrecycling. R‐410A is a very efficient blended refrigerant but it requires knowledgeand skills to be used correctly and safely. Daikin chose PVE as for its properties and easier system dehydration. Daikin does not require dryers, sight glasses, or oil traps on systeminstallations. Expansion must be taken into consideration to prevent fractures or cracksin the gas lines due to temperature increases. Daikin recommends a dedicated tool set including gauges for working onDaikin equipment. 2013 Daikin North America, LLC R‐410A systems require a different flaring block for making flaredconnections. Dry nitrogen purge while brazing prevents oxidation inside of the lines. Pressure test and evacuation must be completed according to bestpractices in the industry. All lines must be insulated including the liquid and the condensate lines. Daikin requires R‐410A to be charged as a liquid and a complete recoveryand recharge in the event of a leak. 2013 Daikin North America, LLCSlide 47Slide 4824
