Installing a split air conditioner (split AC) on the wall involves several steps and should be performed by a licensed HVAC technician or a professional installer, as it requires knowledge of electrical and refrigeration systems. Attempting to install a split AC without proper training and tools can be dangerous and may result in damage or malfunction. However, if you’re interested in understanding the basic process, here’s an overview:
How to Install Split AC on Wall
Materials and Tools Needed:
- Split AC unit (indoor and outdoor)
- Mounting bracket or stand for the outdoor unit
- Mounting bracket for the indoor unit
- Copper tubing for refrigerant lines
- Electrical wires and conduit
- Drill and appropriate drill bits
- Screwdriver and screws
- Pipe bender and cutter
- Tape measure
- Vacuum pump
- Manifold gauge set
- Select a Location:
- Choose a suitable location on the wall for mounting the indoor unit. It should be at least 7 feet above the floor and away from direct sunlight, heat sources, and obstacles that could obstruct airflow.
- Mount the Indoor Unit:
- Secure the indoor unit’s mounting bracket to the wall using appropriate anchors and screws.
- Mount the indoor unit on the bracket securely, ensuring it’s level and well-supported.
- Prepare the Outdoor Unit:
- Choose a location for the outdoor unit that is level, stable, and allows for proper airflow. It should also be away from obstructions and protected from direct sunlight and rain.
- Install a mounting bracket or stand for the outdoor unit, if necessary.
- Run Refrigerant Lines:
- Drill a hole through the wall to run the copper tubing and electrical wires between the indoor and outdoor units.
- Connect the copper tubing, refrigerant lines, and electrical wires, making sure they are properly insulated and sealed to prevent leaks.
- Connect Electrical Wiring:
- Connect the electrical wires from the indoor unit to the outdoor unit, following the manufacturer’s wiring diagram.
- Ensure proper grounding and use conduit to protect the wires.
- Vacuum and Charge the System:
- Use a vacuum pump to remove air and moisture from the refrigerant lines.
- Charge the AC system with the appropriate refrigerant type and amount using a manifold gauge set.
- Test the System:
- Turn on the AC and test its cooling and heating functions.
- Check for refrigerant leaks and ensure proper airflow.
- Verify that the thermostat and remote control are working correctly.
- Seal and Insulate:
- Seal the hole in the wall around the refrigerant lines and electrical wires to prevent drafts and pests.
- Insulate the refrigerant lines to maintain efficiency.
- Complete Installation:
- Secure all components, tighten connections, and clean up the installation area.
- Provide the customer with operating instructions and maintenance guidelines.
Remember, this is a simplified overview of the installation process. Split AC installation requires precise measurements, electrical work, and refrigeration knowledge, making it essential to hire a professional for a safe and efficient installation. Improper installation can result in AC inefficiency, refrigerant leaks, or even damage to the equipment.
