If you can't find studs, use appropriate wall anchors to support the weight of the unit. Mark the locations for the mounting screws and drill pilot holes. Then, attach the mounting bracket to the wall using screws. Once the bracket is securely in place, carefully lift the indoor unit and align it with the bracket. Secure the unit to the bracket according to the manufacturer's instructions. Make sure the unit is firmly attached and doesn't wobble. Double-check the level to ensure it's still straight. Once the indoor unit is mounted, you can move on to the next step.

Installing the Outdoor Unit

Next up is installing the outdoor unit. This involves placing the unit on a level surface and securing it to the ground or a mounting pad. Choose a location that's well-ventilated and away from direct sunlight. Ensure there's enough clearance around the unit for maintenance and repairs. Place the unit on a concrete pad or mounting brackets to provide a stable and level surface. Use shims to level the unit if necessary. Secure the unit to the pad or brackets using bolts or screws. Make sure the unit is firmly attached and doesn't vibrate excessively. Once the outdoor unit is in place, you can move on to connecting the refrigerant lines and electrical wiring.

Connecting Refrigerant Lines

Now comes the tricky part: connecting the refrigerant lines. This requires precision and attention to detail to avoid leaks and ensure proper system performance. Start by measuring and cutting the refrigerant lines to the appropriate length. Use a pipe cutter to make clean, burr-free cuts. Deburr the ends of the pipes to ensure a smooth connection. Use a flaring tool to create flared ends on the pipes. These flared ends will be used to create a tight seal with the fittings on the indoor and outdoor units. Connect the refrigerant lines to the indoor and outdoor units, tightening the fittings securely. Use two wrenches to prevent twisting the pipes. Once the lines are connected, use a vacuum pump to evacuate the system. This removes air and moisture from the lines, which can damage the compressor. Connect the vacuum pump to the service ports on the outdoor unit and run it for at least 30 minutes. Monitor the vacuum gauge to ensure that the system is holding a vacuum. If the vacuum drops, there may be a leak in the connections. Use a refrigerant leak detector to check for leaks and tighten the fittings as needed. Once the system is evacuated, you can release the refrigerant into the system according to the manufacturer's instructions.

Electrical Connections

Electrical connections are critical for the safe and proper operation of your split AC unit. If you're not comfortable working with electricity, it's best to hire a qualified electrician.
