5/1/2014 When cutting copper tubing the cut ends must be de-burred toprovide a square end to eliminate an increased chance of a leak ifthe cut is not properly deburred To properly remove the cut burrs, use a deburring tool to provide asmooth and square cut end in the tubing Be careful to not under cut the inside tube diameter creating achamfered edgeDeburring ToolTubing with burrsDeburred tubingSlide 23 2014 Daikin North America, LLC Use a proper R-410A flare tool for high quality flares R-410A flares are deeper providing more surfacearea for sealing Daikin Flare nuts are heavier than standard R-410Aflare nutsDaikin3/8”FlareStandard3/8”Flare Daikin provides the proper flare nuts on all indoorand outdoor units 2014 Daikin North America, LLCSlide 2412
5/1/2014 Check the flare cone for proper diameter and a smoothpolished finish Use the Daikin Flare Gauge Apply synthetic oil to the cone inner and outer surfaces only Do not lubricate the flare threads Do not use any type of thread sealant on the flare threads Always use a torque wrench to tighten flare nut connections Backup wrench on indoor unit connections required Refer to Installation Manuals for flare nut torque specificationsApply synthetic oil tothe inner and outerflare surfaces onlyBackup wrenchDo not apply oil toflare threads – Do notover tighten flare nutSlide 25 2014 Daikin North America, LLCTorque wrenches are preferred 2014 Daikin North America, LLCSlide 2613

5/1/2014Nitrogen pressure is subject to fluctuation above 300 psi, basedon ambient temperature changes. Use this formula tocompensate for temperature changes from one day to the nextwhen performing the 24 hour pressure test. The followingformula will determine system pressure drop caused by lowambient temperature.Note the Temperature when the system is pressurized (Tp) Subtract theTemperature when the pressure is checked (Tc) Multiply by a factor of0.80 to get the Pressure Drop (PD)( Tp – Tc ) x 0.80 Pressure Drop 2014 Daikin North America, LLCSlide 29Daikin Recommends Triple Evacuation Evacuate the system to 4000 microns, hold for 15 minutes Break vacuum with dry nitrogen to pressure of 2-3 PSIG Evacuate to 1500 microns & maintain for 20 minutes Break vacuum with dry nitrogen to pressure of 2-3 PSIG Evacuate to below 500 microns and hold for 60 minutes 2014 Daikin North America, LLCSlide 3015
5/1/2014Only install driers, oil traps, shut off valves or any other linecomponents in your piping work if instructed to do so in theIOM documents – if no instruction, it’s because it is NOTnecessary (for Daikin).The only acceptable piping is ACR (copper) type tubing whichis dehydrated and sealed at both ends. 2014 Daikin North America, LLC Slide 31Compatible with all HFC RefrigerantsExcellent anti-wear propertiesBetter solubility with process fluidsSuperior Resistance to Cap tube blockageBetter lubricityOptimal for non-drier systemsVery Hygroscopic but with No HydrolysisMoisture easily removed with vacuumCare must be taken to prevent contaminationby the introduction of other oils 2014 Daikin North America, LLCSlide 3216

5/1/2014 VRVIII-S systems are charged with R-410A refrigerant by weight basedon the length of the liquid lines only. All liquid lines should be measured as accurately as possible to ensureoptimum system performance. Each liquid line diameter is multiplied by a factor per measured foot ofpiping. The refrigerant change is designated as the “Additional RefrigerantCharge”.Slide 37 2014 Daikin North America, LLCCharging Connection The “Additional Refrigerant Charge Mode” is used when there is not enough system vacuumfrom the final evacuation cycle to complete the “Additional Refrigerant Charge” amount Connect the high side manifold hose to the charging service port (liquid line service valve), andbleed the hose Low side manifold hose is not used for this procedure Refer to the weight of refrigerant taken on the last cycle of the triple evacuation operation Initiate the “Additional Refrigerant Charge Mode” at the outdoor unit Service PCB Information can be found within the Installation/Operation Manuals and VRV Commissioning Guide When the total calculated refrigerant charge is taken based on the scale reading, close off the High sidegauge 2014 Daikin North America, LLCSlide 3819
