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. 3 70mm 70mm 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 signal wire Piping Lid for right piping Lid for left piping Lid for under piping Fix with adhesive tape Drain hose Drain hose Indoor/outdoor electric cable Change-for-fresh-air tube 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. 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. 4. Attaching Drain-Elbow If the drain-elbow is used, please attach it as figure. (Note: Only for heat pump unit. ) 6 Outdoor unit 6. Purging Method: Push the air out of the indoor unit and piping as followes: (1) Remove the valve cap on 2-way valve in outdoor unit. (2) Loosen by 1/2 turn the flare nut of gas pipe, which is conneted to 3-way valve. (3) Loosen 2-way valve by 90 using hexagon wrench, and after approx. Gas comes out through flare nut on wide pipe. If no gas is discharged, tighten flare nut with specified torque. (4) Open 2-way and 3-way valves using specified torque. (5) Tighten the caps on the valves with specified torque. o 2-way valve Liquid Side 6. 35mm(1/4") Gas Side 9. 52mm(3/8") 12. 7mm(1/2") 3-way valve Flare nut 2-way valve 6. 35mm(1/4") 3-way valve 9. 52mm(3/8") 12. 7mm(1/2") Freshair-3 Freshair-2 HSU-09H03/U(ZXF) HSU-12H03/U(ZXF) 2-way valve 6. 35mm(1/4") 3-way valve 9. 52mm(3/8") 12. 7mm(1/2") HSU-09C03/U(ZXF) HSU-12C03/U(ZXF) Tighten torque N. m Valve rod Valve cap 7-9 20-25 When connecting pipe exceeds 5 meters, 16g refrigerant shall be added per exceeding meter.
