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. 3 30mm Indoor unit 1. Insert the drain hose into the dent of heat insulation materials of indoor unit. Insert the indoor/outdoor electric cable from backside of indoor unit, and pull it out on the front side, then connect them. Coat the flaring seal face with refrigerant oil and connect pipes. Cover the connection part with heat insulation materials closely, and make sure fixing with adhesive tape Heat insulation material Lid for right piping Lid for under piping Lid for left piping Piping Drain hose Indoor/outdoor electric cable Fix with adhesive tape Indoor/outdoor electric cable and drain hose must be bound with refrigerant piping by protecting tape. [Other direction piping] Cut away, with a nipper, the lid for piping according to the piping direction and then bend the pipe according to the position of wall hole. When bending, be careful not to crash pipes. If wiring is not correct, proper operation can not be carried out and controller may be damaged. Fix the cable with a clamp. 4.
