Remove the screw that attaches the mounting that will connect the indoor and outdoor units. plate to the back of the indoor unit. 2. Place the mounting plate against the wall in a location that meets the standards in the Select Installation Location step.(See Mounting Plate Dimensions for detailed information on mounting plate sizes.) 3. Drill holes for mounting screws in places that: have studs and can support the weight of the unit correspond to screw holes in the mounting plate 4. Secure the mounting plate to the wall with the screws provided. S. Make sure that mounting plate is flat against the wall. 1. Determine the location of the wall hole based on the position of the mounting plate. Refer to Mounting Plate Dimensions on the next page to help you determine the optimal position. The wall hole should have a 65mm (2.51n) diameter at least, and at a slightly lower angle to facilitate drainage. 2. Using a 2.5in (65-mm) core drill, drill a hole in the wall. Make sure that the hole is drilled at a slight downward angle, so that the outdoor end of the hole is lowerthan the indoor end by about 0.2-0.275in (5mm to 7mm). This will ensure proper water drainage. (See Fig.3.2) 3. Place the protective wall cuff in the hole.

You must prepare the piping before passing it through the hole in the wall. Refer to the Refrigerant Piping Connection section of this manual for detailed instructions on pipe flaring and flare torque requirements, technique, etc. 1. Based on the position of the wall hole relative to the mounting plate, choose the side from which the piping will exit the unit. 2. If the wall hole is behind the unit, keep the knock -out panel in place. if the wall hole is to the side of the indoor unit, remove the plastic knock -out panel from that side of the unit. (See Fig. 3.3).This will create a slot through which your piping can exit the unit. Use needle nose pliers if the plastic panel is too difficult to remove by hand. Knock -out Panel 3. Use scissors to cut down the length of the insulating sleeve to reveal about 15cm (6in) of the refrigerant piping. This serves two purposes: • To facilitate the Refrigerant Piping Connection process • To facilitate Gas Leak Checks and enable you to check for dents 4. If existing connective piping is already embedded in the wall, proceed directly to the Connect Drain Hose step. If there is no embedded piping, connect the indoor units refrigerant piping to the connective piping that will join the indoor and outdoor units. Refer to the Refrigerant Piping Connection section of this manual for detailed instructions. S. Based on the position of the wall hole relative to the mounting plate, determine the necessary angle of your piping. 6. Grip the refrigerant piping at the base of the bend. 7. Slowly, with even pressure, bend the piping towards the hole. Do no dent or damage the piping during the process. Step 5: Connect drain hose By default, the drain hose is attached to the left- hand side of unit (when you're facing the back of the unit). -However, itcan also be attached to the right-hand side. 1. To ensure proper drainage, attach the drain hose on the same side that your refrigerant piping exits the unit. 2. Attach drain hose extension (purchased separately) to the end of drain hose. 3. Wrap the connection point firmly with Teflon tape to ensure a good seal and to prevent leaks. 4. For the portion of the drain hose that will remain indoors, wrap it with foam pipe insulation to prevent condensation. 5. Remove the air filter and pour a small amount of water into the drain pan to make sure that water flows from the unit smoothly.
