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 isH05RN-F or H07RN-F.2. If the fuse on PC board is broken please change it with the type of3. 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 beall-pole switch and the distance between its two contacts should be not lessthan 3mm.3Power cable: 3G*2.5mm 23(C)1(N) 2(L) 3(C)1(N) 2(L)Indoor unit BOutdoor unit AIndoor unit A1 2 3(C)1 2 3(C)4G0.75mm24G0.75mm 2Outdoor unit B^POWERH2SM-(7+7)H03/R2(DB)ıııIndoor unit AIndoor unit B)C(3)N(1 )L(2 )C(3)N(1 )L(2Outdoor unit AOutdoor unit B^POWER2HUM14HA03/R2(DB)2HUM18HB03/R2(DB)2HUM14H03/R2(DB)Power cable: 3G*2.5mm 2ıOutdoor 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.ƽUse 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.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 of each indoor unit is 5m. If total pipe length is over20m, the function of the unit will be affected, charge more refrigerant is needed,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.Connection of pipescharge additional refrigerant.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.Vacuumize for over 15min.And check the level gauge which should read -0.1MPa3. (76 cm Hg) at Iow pressure side. After the completion of vacuumizing, close thehandle ‘Lo’ in gaugemanifold and stop the operation of the vacuum pump. Checkcondition of the scale and hold it for 1-2min. If the scale-moves back in spite oftightening, make flaring work again, the return to the beginning of 3 .Attaching Drain-ElbowPurging Method:To use vacuum pumpOpen the valve rod for the 2-way valve to an angle of4. anticlockwise 90 degrees.After 6 seconds, close the 2-way valve and make the inspection of gas leakage.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.mIn case the elevation A is more than 5m,oil trap shoud be installed every 5~7mMax.
