Precautions on Installation <br /> z <br /> rn <br /> • Check the strength and level of the installation surface so that the unit does not G <br /> W . <br /> cause any operating vibrations or noise after installation. <br /> • Fix the unit in place securely using foundation bolts, as in the figure. (Prepare 4 acn N <br /> sets of 5/16 inch (M8)or 3/8 inch (M10)foundation bolts, nuts and washers;all <br /> separately available.) <br /> • It is best to screw in the foundation bolts until their ends are 3/4 inch (20mm) A <br /> from the foundation surface. <br /> Outdoor Unit Installation Diagram <br /> RX09/12* RX18*,RXN18* <br /> RK09/12* RXN09/12* RK18*,RKN18*RX24*,RXN24* <br /> RXL09/12* RKNO9/12* RXL15.
