[. . . ] Place, possible to bear the unit, where vibration and noise are not increased. Place, where discharged wind and noise do not cause a nuisance to the neighbors. Place, where a distance marked is available as illustrated in the above figure. receive signals when the fluorescent lamps in the room are lightened. unit are not disturbed. Power Source Before inserting power plug into receptacle, check the voltage without fail. The power source is the same as the corresponding name plate. Install an exclusive branch circuit of the power. [. . . ] Refer to the previous article, " When the mounting plate is first fixed ", for the position of wall hole. Remove terminal cover at right bottom corner of indoor unit, then take off wiring cover by removing its screws. When connecting the cable after installing the indoor unit 1. Insert from outside the room cable into left side of the wall hole, in which the pipe has already existed. Pull out the cable on the front side, and connect the cable making a loop. 2 Making a Hole on the Wall and Fitting the Piping Hole Cover Make a hole of 60 mm in diameter, slightly descending to outside the wall. Install piping hole cover and seal it off with putty after installation Wall hole Ø60mm When connecting the cable before installing the indoor unit Insert the cable from the back Loosen the screws and insert Pull the cable slightly to tightened. the cable ends fully into terminal block, then Indoor side Thickness of wall Outdoor side (Section of wall hole) G Piping hole pipe make sure the cables have been properly inserted and 2 Outdoor unit After the cable connection, wiring cover. never fail to fasten the connected cable with the 1 Installation of Outdoor Unit Install according to Drawing for the installation of indoor and outdoor units 2 Note When connecting the cable, confirm the terminal number of indoor and outdoor units carefully. If wiring is not correct, proper operation can not be carried out and will cause defect. Connection of pipes To bend a pipe, give the roundness as large as possible not to crush the pipe , Connecting the pipe of gas side first makes working easier. The connection pipe is specialized for R410A. Half union Flare nut Forced fastening without careful centering may damage the threads and cause a leakage of gas. Pipe Diameter() Liquid side6. 35mm(1/4") Liquid/Gas side9. 52mm(3/8") Gas side 12. 7mm(1/2") Spanner Torque wrench Gas side 15. 88mm(5/8") Fastening torque 18N. m 42 N. m 55N. m 60 N. m and the bending radius should be 30 to 40 mm or longer. 4G1. 5mm 2 Indoor unit Power cable: 3G1. 5mm2 HSU-09HR03/R2(DB) HSU-12HR03/R2(DB) HSU-09RUG03/R2(SDB) HSU-12RUG03/R2(SDB) HSU-09RK03/R2(SDB) HSU-12RK03/R2(SDB) Outdoor unit Be careful that matters, such as wastes of sands, etc. 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 professional air conditioner engineer. Before adding additional refrigerant, perform air purging from the refrigerant pipes and indoor unit using a vacuum pump, then charge additional refrigerant. CAUTION Outdoor unit B A Indoor unit B A Indoor unit Outdoor unit 34 Outdoor unit B A Max. Elevation: Amax=10m In case the elevation A is more than 5m, oil trap shoud be installed every 5~7m Max. Length: Bmax=15m In case the pipe length B is more than 7m, the refrigerant should be charged, according to 20 g/m. Oil trap Indoor unit 1(L ) 2 (N) 4 Indoor unit Outdoor unit Power cable: 3G1. 0mm 2 Connecting wiring: 3G1. 0mm 2 (For: L N )+2x0. 75mm 2 HSU-09HRA103/R2 HSU-12HRA103/R2 3 Connection Use the same method on indoor unit. Loosen the screws on terminal block and insert the plugs fully into terminal block, then tighten the screws. Insert the cable according to terminal number in the same manner as the indoor unit. If wiring is not correct, proper operation can not be carried out and controller may be damaged. If the supply cord is damaged, it must be replaced by the manufacturer or its service agent or a similar qualified person. If the fuse on PC board is broken please change it with the type of T. The breaker should be all-pole switch and the distance between its two contacts should be not less than 3mm. 4 Attaching Drain-Elbow If the drain-elbow is used, please attach it as figure. (Note: Only for heat pump unit. ) 5 1. Purging Method:To use vacuum pump Detach the service port's cap of 3-way valve, the valve rod's cap for 2-way valve and 3-way's, connect the service port into the projection of charge hose (Iow) for gaugemanifold. [. . . ] Detach the charge hose from the service port, open 2-way valve and 3-way. Turn the valve rod anticlockwiseuntil hitting lightly. 7. To prevent the gas leakage, turn the service port's cap, the valve rod's cap for 2-way valve and 3-way's a little more than the point where the torque increases suddenly. (Over I0A) In the case of installing an air conditioner in a moist place, please install an earth leakage breaker. For installation in other places, use a circuit breaker as far as possible. Check for Installation and Test Run Please kindly explain to our customers how to operate through the instruction manual. 2 Cutting and Flaring Work of Piping be removed. Pipe cutting is carried out with a pipe cutter and burs must After inserting the flare nut, flaring work is carried out. Flare tool for R410A Clutch-type A 0~0. 5mm Check Items for Test Run Put check mark in boxes Gas leak from pipe connecting? [. . . ]
