5Inverter Series MICRO 7.1kW (3HP) ~ 25.0kW (10HP) XFirstly, let’s look at the line-up of our new PAC.We have a new model for 1.5, 2.0 & 2.5HP outdoor units, ZIX-S, which is the replacement of the previous SRC**ZHX-S.♪XX55
7Model Name For example, F D C 140 V N X X hyper ,Hi EER /- micro seriesPower source N: 1 phase / S: 3 phaseSymbol for inverter model for PACCapacity code (14.0kW)As you may noticed, our new model names are a bit different from the previous FD series.For example, the 6HP model FDC140VN/S.♪Letter FD, keeping the same meaning of the existing one, shows the symbol of single split PAC.Letter C is the symbol of outdoor unit.The digits after C show the nominal capacity of the unit as we mentioned just now.As for 8HP unit, 200 means 20 kilowatts, and 6/5/4 HP models respectively show 140/125/112 in their model names. 3HP equals to 7.1 kilowatts which show 71 in the model name.Letter V is the symbol of inverter compressor.Letters N/S mean the different power source. N means single phrase and S means three phrases.Symbol for outdoor unitSymbol for split PAC7

11For European countries Indoor Unit : FDT-4-way Ceiling Cassette FDT-Industry Leading COPall models clearedCLASS ANext, I would like to introduce the new ceiling cassette -4way- indoor units, which have realized industry leading COP and cleared Class A standard with the highest energy saving level.♪I will start with the new features, following by the new designed air flow control, improved air-conditioning feeling and new remote controller.For European countries11
12"New" Design Ceiling cassette -4way- type Ceiling Cassette : FDT1-1: Individual flap control system"New" Design Ceiling cassette -4way- typeAccording to room temperature conditions, air flow in four direction can be individually controlled by four flaps.New air outlet design brings sufficient air flow and long of air flow throw is realized.CurrentNew
13Efficiency is increased by 30% !! Ceiling Cassette : FDT1-2 : Compact but High COP# Thin heightNewly designed of heat exchanger changed from 2 separate assemblies to 1 single assembly, the height of indoor unit was reduced drastically.Current# High efficiencyNew design brings,- Reduction of air flow pressure loss (=Decrease of Fan motor load)Using high efficient piping, high performance heat exchanger,- Increase in heat transfer efficiencyEfficiency is increased by 30% !!

But some interfaces will be needed for the connection.Here is the list of optional kits, which is using for RAC&PAC models connection to superlink network.There are three different models.Remote Controller adapter will be applied when RAC units are needed to be controlled by wired remote controllers. SC-BIK1-E is using for SRK**ZG-S models controlled by the old RC-E1R, while SC-BIKN-E is connecting SRK**ZHX-S or the new SRK**ZIX-S models to the new 2-core controller RC-E3.Superlink adapter SC-AD-ER & SC-ADN-E are using for RAC/PAC systems to connect into superlink network. SC-AD-ER is used for the previous superlink 1 and 3-core wiring remote controller RC-E1, while SC-ADN-E is used for the new superlink 2 and 2-core wirings remote controller RC-E3.Remote sensor SC-THB-E3, which is a wildly used remote sensor, can change to the remote detected temperature instead of the original temperature of intake air. It is available for all of our new KX6 & PAC indoor units.♪
22Superlink Network Structure with PAC & RAC SC-SL1N-EKX6 SeriesRAC series(SRK50/60ZHX-S)SuperlinkNetwork(Superlink II)SC-BIKN-EHere we can see the superlink network structure including KX6, PAC & RAC.♪As we all know, the new superlink network applies 2-core wirings connecting outdoor unit, indoor units and centralized remote controllers as SC-SL1N-E & SC-SL2N-E.RAC series such as SRK50/60ZHX-S are using 3-core wirings for connecting o/u & i/u.As we mentioned in the previous slide, SC-BIKN-E should be connected as an adapter when RAC model is controlled by RC-E3.When RAC is connected into the new superlink network, it must be connected through SC-ADN-E to the new protocol network, and 2-core wiring is applied.In terms of PAC series, 3-core cable is using between the outdoor unit and indoor units.Again, same as RAC units, SC-ADN-E should be connected between PAC units and superlink network. 2-core wirings are applied.Now let’s look at the detail of each kit.SC-SL2N-ESC-ADN-ESC-ADN-ESC-ADN-E2222
