3Note When connecting the cable, confirm the terminal number of indoor andoutdoor units carefully. If wiring is not correct, proper operation can notbe carried out and will cause defect.1. If the supply cord is damaged, it must be replaced by the manufacturer or itsservice agent or a similar qualified person. The type of connecting wire is H05RN-For H07RN-F.2. If the fuse on PC board is broken please change it with the type of T. 3.15A/250V.3. The wiring method should be in line with the local wiring standard.4. After installation, the power plug should be easily reached.5. A breaker should be incorporated into fixed wiring. The breaker should be all-poleswitch and the distance between its two contacts should be not less than 3mm.Outdoor unitInstall according to Drawing for the installation of indoor and outdoor unitsTo bend a pipe, give the roundness as large as possible not to crush the pipe ,ƽand the bending radius should be 30 to 40 mm or longer.Connecting the pipe of gas side first makes working easier.ƽThe connection pipe is specialized for R410A.ƽInstallation of Outdoor UnitHalf union Flare nutTorque wrenchBe careful that matters, such as wastes of sands, etc. shall not enter the pipe.The standard pipe length is 5m. If it is over 7m, the function of the unit will beaffected. If the pipe has to be lengthened, the refrigerant should be charged,according to 20 g/m. But the charge of refrigerant must be conducted by profes-sional air conditioner engineer. Before adding additional refrigerant, perform airpurging from the refrigerant pipes and indoor unit using a vacuum pump,thenSpannerForced fastening without careful centering maydamage the threads and cause a leakage of gas.Pipe Diameter(ǿ) Fastening torqueLiquid side6.35mm(1/4") 18N.mLiquid/Gas side9.52mm(3/8") 42 N.mGas side 12.7mm(1/2") 55N.mGas side 15.88mm(5/8") 60 N.mConnection of pipescharge additional refrigerant.Use the same method on indoor unit. Loosen the screws onƽ terminal block andinsert the plugs fully into terminal block, then tighten the screws.Insert the cable according to terminal number in the same manner as the indoorunit.ƽIf wiring is not correct, proper operation can not be carried out and controllermay be damaged.ƽFix the cable with a clamp.ƽCAUTIONMax.Elevation:●In case the elevation A is more● than 5m, oil trap shoud beinstalled every 5~7mMax. Length:●In case the pipe length B is● more than 7m, the refrigerantshould be charged, accordingto 20 g/m.ConnectionIf the drain-elbow is used,ƽ please attach it as figure. (Note:Only for heat pump unit.)Detach the service port’s cap of1. 3-way valve, the valve rod’s cap for 2-way valveand 3-way’s, connect the service port into the projection of charge hose (Iow)for gaugemanifold. Then connect the projection of charge hose (center) for gau-gemanifold into vacuum pump.Open the handle at Iow in2. gaugemanifold, operate vacuum pump. If the scale-moves of gause (Iow) reach vacuum condition in a moment, check 1. again.Attaching Drain-ElbowPurging Method:To use vacuum pumpA1max=10mB1max=15mABOutdoor unitIndoor unitA1B1Indoor unitA2B2Outdoor unitIndoor unitOil trapOutdoor unitIndoor unitA1B1Indoor unitA2B2A2max=10mB2max=15mInsert the cable from the backƽ side of the unit, then pull it out on the front side.Loosen the screws and insertƽ the cable ends fully into terminal block, thentighten the screws.Pull the cable slightly toƽ make sure the cables have been properly inserted andtightened.After the cable connection,ƽ never fail to fasten the connected cable with thewiring cover.When connecting the cable before installing the indoor unitPower cable: 3G2.5mmOutdoor unitREWOP1 32 1 2Indoor unit AIndoor unit B{4G0.75mm24G0.75mm 2ııL N1)(2)(H2SM-(9+9)HEA03/R2H2SM-(9+12)HEA03/R2H2SM-(9+9)HRA03/R2H2SM-(9+12)HRA03/R2H2SM-(9+12)HEK03/R2(C) 3 (C)1.
