Loosen the screws and insert the cable ends fully into terminal block, then tighten the screws. Pull the cable slightly to make sure the cables have been properly inserted and tightened. After the cable connection, never fail to fasten the connected cable with the wiring cover. Indoor side Outdoor side (Section of wall hole) G Piping hole pipe Installation of the Indoor Unit Drawing of pipe [ Rear piping ] Draw pipes and the drain hose, then fasten them with the adhesive tape [ Left Left-rear piping ] In case of left side piping, cut away, with a nipper, the lid for left piping. In case of left-rear piping, bend the pipes according to the piping direction to the mark of hole for left-rear piping which is marked on heat insulation materials. Note When connecting the cable, con rm 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. 37 HSU-18HEK03/R2 Installation Outdoor unit Installation of Outdoor Unit Install according to Drawing for the installation of indoor and outdoor units 3 4 Connection of pipes To bend a pipe, give the roundness as large as possible not to crush the pipe , and the bending radius should be 30 to 40 mm or longer.

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. 34 CAUTION Outdoor unit Indoor unit Power cable: . 5mm Connecting wiring: 5mm 2 (For: L N )+2x0. 75mm 2 HSU-18HEK03/R2 HSU-18HEA03/R2 HSU-18RH03/R2 HSU-18HRA03/R2 HSU-18HV03/R2 Outdoor unit Outdoor unit 2 Outdoor unit B A A Indoor unit B Indoor unit B Oil trap Indoor unit A Max.

If the supply cord is damaged, it must be replaced by the manufacturer or its service agent or a similar quali ed 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. 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. Fix the cable with a clamp. Attaching Drain-Elbow If the drain-elbow is used, please attach it as gure. (Note: Only for heat pump unit. ) Purging Method:To use vacuum pump 1. 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. [. . . ] In case that the attached drain hose is in a room, please apply heat insulation to it without fail. 6. 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.
