CAUTION f installation is done in inappropriate space, unit may generate sound and I cause bad effect on the product. Therefore before fixing the installation plate to a wall or a window frame, you must determine the position of the 65mm hole through which the cable, pipe and hose pass to connect the indoor unit to the outdoor unit. When facing the wall, the pipe and cable can be connected from the: Right (A) Direction of pipe Left (B) Underside_right (C) Rear_right or left (D) A D C D B 1 Determine the position of the pipe and drain hose hole as seen in the picture and drill the hole with an inner diameter of 65mm so that it slants slightly downwards. CAUTION Make sure to drill only one hole after choosing the direction of the pipe. (Unit : mm) Pipe hole (Ø65mm) 27 AS09/AS12 120 68 2 Fix the indoor unit. If you fix the indoor unit on a wall (1) Fix the installation plate to the wall giving attention to the weight of the indoor unit. Note If you mount the plate to a concrete wall using plastic anchors, make sure that gaps between the wall and the plate, created by projected anchor, is less than 20mm. (Unit : mm) Pipe hole (Ø65mm) 34 34 140 68 AS18/AS24 Plastic Anchor <20mm Wall If you fix the indoor unit on a window frame (1) Determine the positions of the wooden uprights to be attached to the window frame. (2) Attach the wooden uprights to the window frame giving attention to the weight of the indoor unit. (3) Attach the installation plate to the wooden upright using tapping screws. If you fix the indoor unit on a gypsum board (1) Use stud finder to find out locations of the studs. The connection procedure for the refrigerant pipe varies according to the exit position of the pipe when facing the wall: Right(A) Left(B) Underside(C) Rear A C B 1 2 3 Cut out the appropriate knock-out piece (A, B, C) on the rear of the indoor unit unless you connect the pipe directly from the rear. Remove the protection caps of the pipes and connect the assembly pipe to each pipe. Tighten the nuts first with your hands, and then with a torque wrench, applying the following torque: Outer Diameter ø6. 35 mm ø9. 52 mm ø12. 70 mm ø15. 88 mm ø19. 05 mm ø22. 23 mm Torque (kgf·cm) 140~170 250~280 380~420 440~480 990~1210 990~1210 Note If you want to shorten or extend the pipes, refer to page 14. 4 5 Cut off the remaining foam insulation. If necessary, bend the pipe to fit along the bottom of the indoor unit. Then pull it out through the appropriate hole. The pipe should not project from the rear of the indoor unit. The bending radius should be 100 mm or more. Pass the pipe through the hole in the wall. For further details on how to connect to the outdoor unit and purge the air, refer to page 17. The pipe will be insulated and fixed permanently into position after finishing the installation and the gas leak test; refer to page 19 for further details. 6 7 Note CAUTION Tighten the flare nut with torque wrench according to specified method. If the flare nut is over-tightened, the flare may break and cause refrigerant gas leakage. [. . . ] The purge time is normal. Refer to the Service Manual for further details. CAUTION The remaining air in the Refrigeration cycle, which contains moisture, may cause malfunction on the compressor. Always contact the service center or a professional installation agency for product installation. Performing the Gas Leak Tests Make sure to check for gas leaks before completing the installation process (connecting the assembly pipe and hose between indoor unit and outdoor unit, insulating the cables, hose and pipe, and fixing the indoor unit to the installation plate).
